How much rebar is in a ton
Such building material as steel reinforcement is today very often used in the field of metal rolling. Sometimes, of course, you can find carbon fiber reinforcement.
It is also used in construction work, in a wide variety of structures and structures in conjunction with reinforced concrete, in order to increase the strength of a material such as concrete.
In addition to everything else, steel reinforcement is known for its reliability and durability. That is why it is used in modern construction.
It is also important to know how much reinforcement is in a ton, immediately before starting any construction work. Based on this, it is possible to calculate the required amount of building material that will be needed for the future structure.
The manufacturing process of fittings and its purpose
In particular, the process of manufacturing reinforcement is carried out from round and hot-rolled steel with a periodic profile.
The reinforcement of the presented type is used to reinforce walls or floors in buildings and structures that are made of monolith.
In general, the main purpose of such reinforcement is, first of all, the process of reinforcing to increase the durability of a particular structure, which consists of iron, as well as concrete, in the aggregate.
With all this, such reinforcement is carried out in a prestressed state, or in a normal state, based on the situation.
All this will give structures of this kind even more strength, and will also protect them from various harmful factors and deformations.
Reinforcement placement options
By the way , there are several variations so that you can place reinforcement from a rod inside the structure itself, which consists of concrete and iron, and again, in total.
The longitudinal area is subject to regulation, tension, stretching, and at the same time, it will reduce all the risks of various cracks.
But as for the transverse discharge, it is, first of all, used to reduce the risk of inclined cracks, and also, such a discharge unites concrete in a compressed state.
Application of reinforcement in construction
Very often, during construction, in a variety of areas, specialized reinforcement of completely different diameters and dimensions is used.
It is important to know how much reinforcement is contained in a ton. In particular, dimensions such as 11, 13, 14 and 17 millimeters of the grade of steel that is determined by category A-500 C .
When the quantity required for a particular reinforcement is calculated, and in tons, it must be used in the construction of the foundation, its quantity is calculated in those meters, which are called linear meters.
In other words, after the calculation has been carried out, you can understand how much reinforcement is needed in order to carry out the process of reinforcing a particular structure or structure.
But as for sales, here the measure of the quantity of a structure is precisely tons and not other indicators of this kind. That is why, in order to distribute the final cost that is needed for construction.
How many meters there are in one ton of the structure itself will directly depend on the size of the reinforcement. That is, the thinner the structure, the higher the content of the meter measurements in 1 ton, and for this you need to know how many meters of reinforcement are in a ton.
Determination of reinforcement weight
To determine a more accurate weight of reinforcement based on the purpose of its dimensions, initially, it is imperative to know its diameter.
Without this indicator, it will be impossible to advance. That is why, initially, it is necessary to start the construction process after you already know exactly the variation in the profile of a metal product.
For example , for reinforcement that has a rod diameter of 7 millimeters, the weight category will be about 0.221 kilograms. And this is only in water meter.
But for the reinforcement itself d 7-0.394 kilograms, for the reinforcement d 11-0.618 kilograms also, in one meter. For reinforcement with a diameter of 11 millimeters, 0.887 kilograms will be required.
In order to calculate a certain amount of reinforcement, you need to know not only the diameter, but also its dimension, and also take into account all the conditions and criteria for use.
That is why , for the presented calculations, a specialized program is used. Naturally, absolutely all specialists who have extensive experience in construction and have directly used steel reinforcement in practice more than once know this.
Thus, it is necessary to turn to them for useful information.
But to apply it successfully, you must initially be aware of all the basic operations. They are simply necessary for operations in a mathematical direction; for example, there are online foundation calculators, which also indicate the reinforcement.
You only need to enter all the data into such a program, and it will give you a ready-made result. It is very convenient and quite simple in labor-intensive processes. This is how the amount of a ton that is in the reinforcement is calculated.

How many rods of 12 rebar are in a ton?
Reinforcement is a set of interconnected elements that, when working together with concrete in reinforced concrete structures, perceive tensile stresses (although they can also be used to strengthen concrete in a compressed zone).
The main application of periodic profile reinforcing steel is in the construction of foundations and walls of buildings and structures made of monolithic concrete.
When carrying out concrete work, a significant investment of time and money requires the installation of a reinforced frame to reinforce structures made from reinforcing mesh.
To calculate the order volume, you need to know how many kg per meter of reinforcement and the number of linear meters of reinforcing steel.
The weight of a meter of reinforcement is presented in the table of the ratio of diameter and weight of 1 m. Knowing the weight of reinforcing steel according to GOST 5781-82, you can estimate the reinforcement coefficient of the structure (the ratio of the mass of the reinforcement to the volume of concrete) and determine how much material is needed for the foundation (per cube of concrete)
A linear meter of reinforcement is individual reinforcing bars of a smooth and periodic profile 1 meter long, the weight of which depends on the diameter of the reinforcing steel GOST 5781-82 (from a range of diameter sizes of periodic steel - 6, 8.10, 12, 14, 16, 18.20, 22, 25, 28, 32, 36, 40, 45, 50, 55, 60, 70, 80 mm).
How much does the reinforcing mesh weigh for screeding, performing plastering work, for making a reinforced concrete foundation frame (concrete + connected reinforcement bars), what is the weight of the reinforcing mesh for brickwork, depends on the size of the cards (length, width of the canvas), the size of the cell (square mm x mm ) and reinforcing wire diameter (mm).
Construction organizations use reinforcement produced in Ukraine, the weight of which meets the requirements of GOST, since domestic reinforcing steel is of sufficiently high quality and complies with all GOSTs and standards for rolled metal.
The weight of the reinforcement is selected depending on the types according to GOST, diameter sizes (see.
table - “Specific gravity of reinforcement in a linear meter”) and the scope of application of the periodic profile.
The weight of a linear meter of reinforcement depends on the shape of the surface of the periodic profile: corrugated or smooth on the outside. Protrusions in the form of ribs, corrugations on the surface of periodically profiled reinforcing steel bars or ribbed wire steel significantly improve adhesion to concrete and its characteristics.
The range of reinforcement, depending on the manufacturing technology of reinforcing steel for reinforced concrete structures, is divided into hot-rolled rod and cold-drawn wire steel.
The weight of 1 m of hot-rolled reinforcement does not depend on its basic mechanical characteristics, which are divided into six assortment classes depending on the strength of the metal and steel grade, with the symbol: AI, A-II, A-III, A-IV, AV, A- VI.
| Reinforcing steel class | Profile diameter, mm | Reinforcement steel grade |
| AI (A240) | 6-40 | St3kp, St3ps, St3sp |
| A-II (A300) | 10-40 40-80 | St5sp, St5ps 18G2S |
| Ac-II (Ac300) | 10-32 (36-40) | 10GT |
| A-III (A400) | 6-40 6-22 | 35GS, 25G2S 32G2Rps |
| A-IV (A600) | 10-32 (6-8)(36-40) | 80С 20ХГ2Ц |
| AV (A800) | (6-8) 10-32(36-40) | 23Х2Г2Т |
| A-VI (A1000) | 10-22 | 22Kh2G2AYu, 22Kh2G2R, 20Kh2G2SR |
For example, A3 construction reinforcement is used to strengthen concrete structures of prefabricated buildings and is widely used by construction companies in Kyiv. The actual weight of construction reinforcement consists of the mass of the reinforcement frames of the elements (foundation, walls, concrete floors) of a monolithic building, welded mesh, which are then filled with concrete mortar over the formwork.
The production of reinforcing steel in Ukraine is carried out using technologies developed in Soviet times in the field of metal processing, and, as a rule, on equipment inherited from the USSR, and that is why domestic manufacturers sell reinforcing steel at a fairly affordable price with good quality and compliance with GOST requirements .
Reinforcement 8, 10, 12, 14, 16, 18, 20, 22, 25 are the most popular in terms of the diameter of the periodic profile, sold by Ukrainian manufacturers. Imported analogues have a higher price.
Before being sold from metal warehouses, fittings in Ukraine undergo step-by-step quality control during the production process, which guarantees high quality that meets state standards GOST.
What is the weight of the reinforcement along its length?
The weight of the reinforcing steel required for purchase is calculated by multiplying the total length of all the bars in the bundle by the weight of a linear meter of reinforcement (see the table of mass 1 m and how many meters are in a ton of reinforcement). Conversion from meters to tons is carried out by multiplying the specific weight of the reinforcement (weight of 1 meter) by the number of linear meters.
Below is a table of reinforcement sections, the specific weight of 1 linear meter A1 (A240), A2 (A300), A3 (A400), A4 (A800), A5 (A800), A6 (A1000), the number of meters per ton to convert weight to total the length of all the rods in the package or coil.
The reinforcement in coils allows you to cut rods of any required length to size, which will reduce the amount of waste and eliminate the need to splice individual rods of standard length (6 or 12 meters).
Reinforcing steel weight table - How much does 1 m of reinforcement weigh?

Calculation of the weight of reinforcement, welded mesh
If you don’t have a reinforcement calculation table or an online metal calculator at hand, then you can calculate the total weight of the reinforcing mesh yourself by determining the total length of the wire that makes up the welded mesh measuring 1 m2 and multiplying the number of meters by the specific weight of a linear meter of wire.
In the absence of a reference book, you can calculate the weight of a linear meter of reinforcement yourself, using a regular calculator. The volume of metal in 1 meter of steel cylinder is 1 m x (3.14 x D x D/4). In parentheses is the geometric area of a circle with diameter D. The weight of the rod is obtained by multiplying the volume by the specific weight of the reinforcement, which is equal to 7850 kg/m3.
Using this method, you can calculate how many kg are in a meter of reinforcement, and convert tons into meters.
For example, using a calculator, we will calculate the weight of 1 m of reinforcement with a diameter of 12 mm: Volume of metal - 1 m x (3.14 x 0.012 m x 0.012 m/4) = 0.00011304 m3,
Specific gravity - 0.00011304 m3 x 7850 kg/m3 = 0.887 kg. Approximately equal to the value in the table of reinforcement with theoretic weight.
If the length of the reinforcement is 12 m, then we substitute the required value of the rolled steel length into the formula and calculate the weight of the rods. To determine the weight of the mesh, you need to multiply the resulting mass of 1 m2 of mesh by the number of square meters in the welded reinforcement frame.
One more example. Let's calculate the weight of a 100x100x4 mesh with an area of 1 m2. The welded mesh consists of 18 welded reinforcing bars 1 m long. The total length of the rods will be 18x1=18 meters. The specific gravity of 4mm reinforcing wire is 0.092 kg/m. Then the mass of a linear meter of mesh with a height of 1 m will be 18x0.092 = 1.66 kg/m2 + 1% of the mass of welding materials.

Reinforcement 12: Calculation, weight, price
Calculation of the amount of reinforcement. Cost of one meter. Characteristics and GOSTs.
The choice of diameter of rod reinforcement for reinforced concrete structures depends on the load and operating conditions of the object. Starting from 12 millimeters and above, rods are used for load-bearing supports, walls, foundations, building frames, floors, highways, and bridges with significant loads. It is reinforcement 12 that is most in demand in construction. This is due to its high-quality physical characteristics and favorable price.
Steel grades for 12 mm GOST bars
Production is based on the hot-rolled method of producing shaped metal products. According to their technical properties, products are divided into prestressed and non-tensioned. Prestressed ones make it possible to achieve high bending strength, which is important in structures with pronounced lateral pressure. This type of rod is most often made from the following grades of carbon and low-alloy steel:
- st3, 32G2Rps, 25G2S, 35 GS.
Requirements for steel and assortment for rods d=12 are regulated by: GOST 10884-94, GOST 5781-82. In a concrete structure, reinforcement 12 enhances the strength properties of the finished building.
At the same time, the rods themselves take certain loads and protect the frozen block, for example, a foundation, from concrete cracking during its hardening and operation. This is the main purpose of using rods.
And this type is advantageous due to its high-quality physical characteristics, suitable for the loads of low-rise residential buildings, and an attractive price (compared to higher and more expensive brands).
Features of a periodic profile
Rods of this parameter are produced with a smooth or corrugated surface. Continuous profile rods (corrugated) have undeniable advantages when protrusions are located in a spiral or along the axis of the rod. In the marking, the designation of the diameter of such rods means the average data of 2 values:
- Internal (implies the diameter of the rod body only);
- External (indicates the size of the entire diameter, with protrusions).
Parameters: diameters, area, weight, length
Rods of 12 millimeters have a rod body d (internal) of 11.3 mm; d external 13.7 mm. The cross-sectional area is 1.131 cm2. The weight of 1 meter of profile is 0.888 kg. 1 ton contains 1126.13 m of product.
Slicing and packaging
Production is possible in 2 ways: hot-rolled and cold-formed. Rods are produced from ferrous rolled products using the hot-rolled method, and from non-ferrous metals - using the cold-rolling method. The price of the rods depends on this parameter, regardless of the method of cutting rolled metal:
- Rods of measured length;
- Profile of unmeasured length in packs.
12 mm reinforcement is packaged in bundles, the range of rod lengths is 6-12 meters. However, by agreement, it is possible to cut the rods into segments of any length from 3 to 25 m. Standardly, 1 rod of reinforcement is cut to a length of 11.75 m. From here you can calculate its weight, which at this length will be 10.43 kg. At the same time, a ton of profile contains 1126 meters.
Reinforcement calculation 12
To calculate how many meters of rods are needed, the total mass is divided by the weight of one meter. It is important to know that rods have theoretical and actual weights, which differ due to the fact that the values are standardized within certain tolerance ranges. That is why the weight when releasing products may differ slightly, up or down from that stated in GOST 5781-82 for one linear meter and the entire order as a whole.
In order to find out the actual weight of the released rods, a control weighing of the total tonnage of the batch is carried out directly during loading. It should be noted that the maximum deviations that regulate weight are also indicated in the standards. If 12 mm reinforcement is weighed, these deviations can range from -6% to +5% according to GOST 5781-82.
Smooth profile
Smooth rods for construction are produced by the hot-rolled method, hardness class A1. Products are cut, as agreed with the customer, either standardly or to custom lengths. This type of profile has no protrusions or ribs. Welded steel reinforcement has the ability to be welded efficiently without loss of tensile and bending strength. This also applies to corrugated products.
Price of fittings dn=12 mm
The price of rod reinforcement is indicated per linear meter and per ton; more often, the manufacturer indicates the cost per ton based on the finished length of the segments. In this case, the customer can receive cuts of any length. Knowing how much 1 ton will cost and the number of meters in it, you can calculate what the price is for 1 meter of rods.
In the Moscow region, 1 meter of reinforcement with a nominal diameter of 12 costs from 24 rubles (periodic profile).
Smooth profile, price per 1 meter:
- From 29 rubles (retail);
- From 28 rub. small wholesale;
- From 27 rub. large wholesale
The price of reinforcement per ton is from 25,900 rubles (grade A500/35GS) with a standard cut of 11.7 m. With a rod length of 6 meters - from 26 thousand rubles. subject to the purchase of a wholesale batch of 20 tons.
The cost of one meter with a rod length of 3 m is 28 rubles. The lowest price per meter is 21.5 rubles. with standard cutting 11.7 m (A3, A500C). Reinforcement with a nominal diameter of 12 millimeters is used mainly for reinforcing high-grade concrete.

What is the required amount of reinforcement per 1 m3 of concrete?
During the design of large structures, all calculations for materials are carried out in strict accordance with the project and regulatory documents. The consumption of reinforcement per 1 m3 of concrete is also important for small buildings in private construction, because incorrect placement of rods can lead to a number of defects and unreliability of the completed structure. To determine the required number of components, mathematical formulas are used.
The need for reinforcement of the structure
Structural reinforcement is performed to create a stable foundation and structural elements. The base of the monolith is subject to tensile forces, which are resisted by the reinforcing frame.
The purpose of the building affects the amount of metal and its standard weight in the concrete layer, as well as the type. When developing a detailed design, all possible loads are taken into account.
This is not only the load of concrete with reinforcement on the base of the structure, but also the condition of the soil on which the building is erected, the influence of groundwater or an aggressive environment (snow, wind, rain).
Why is it necessary to monitor the use of fittings?
Calculating the amount of reinforcement is necessary for the strength of the structure, as well as reducing construction costs.
The consumption of reinforcement per cube of concrete allows you to determine the required amount of material - the concrete component and the frame.
If there are not enough steel elements, the structure will be fragile. If much more rods are laid than necessary, this will incur additional costs, and this is not necessary.
Therefore, the amount of reinforcement in 1 m³ of concrete is calculated according to 3 basic information about construction:
- type of soil;
- calculation of reinforcing bars;
- foundation slab load.
To understand exactly what Ø and laying pitch is required when constructing the foundation, it is necessary to carry out calculations or lay elements with a large margin of safety and a minimum pitch.
Calculation of reinforcement for the base of a building: methods
Calculating the number of reinforcement elements for the foundation requires the use of state budget standards (SN 81-02-06-81) or FER and GOST-5781. The estimate standards indicate that the reinforcement of a monolithic base of a building with a volume of up to 5 cubic meters. meters use 1 ton of steel.
In the collection of individual repair and construction works, calculations for the action of operational load are carried out depending on the type of building foundation being performed (volumetric or flat). The design norm between them can be with a difference of more than 100 kilograms of alloys per 1 cubic meter.
View “GOST 5781-82” or download in PDF (816.3 KB)
There are standards that indicate how much material is recommended to be used, depending on the type of foundation.
Rough indicators for the volume of reinforcement used for the construction of foundations, depending on the type, were calculated in kg/m3:
- strip bookmark - 20;
- slab monolithic - 50;
- columnar - 10.
The Building Codes and Regulations (SNiP 52-01-2003 and VSN 416-81 addition 452-84) provide data for calculating the material of standard construction. To do this, you need to know the height, depth of the laying and the supporting area, and from the tables determine the weight, length and class of wire, the number of rods per unit area.
Since they are laid in a concrete layer below and above the concrete, when determining the values they are based on the type of building material and the type of floor. The more massive and heavier the building, the larger the diameter of the rods. Light structures are laid with rods of 10-12 mm, heavy ones - up to 18 mm. For reinforced concrete, one of the important indicators is the density of the concrete mixture.
Steel elements are used in larger quantities at lower densities.
Construction of a slab foundation
The thickness of the slab affects the placement of reinforcement. If it is less than 15 cm, then the rods are laid in 1 layer. If the indicator exceeds these values, a mesh frame should be made.
The length of the cells depends on the material used; reinforced concrete walls are made in squares of 20 cm, and for light buildings using aerated concrete or hollow brick up to 40 cm.
For example, the length is 4 m, the height is 0.4 m, and the width is 6 m, the rods are 12 mm, in the ratio tables we determine that 500 m of reinforcement will be needed - 21 rows horizontally and 31 vertically.
Arrangement of strip foundation
The easiest to calculate is a strip base, for which reinforcement is laid out every 20 cm.
For this type of foundation, longitudinal reinforcement is used. Basically, reinforcement is laid out every 20 cm along the width of the base. Therefore, it is not difficult to calculate the quantity, knowing the initial data. All internal and adjacent walls are made with a lower laying frequency and diameter.
Example: if 6 steel elements are laid out along the width of a structural element, then to obtain the exact amount of all reinforcement, the perimeter of the tape is multiplied by 6. Vertical elements are laid every 1 m, depending on the depth of the laying and the height of the walls.
The distance of laying the rods to the edges of the concrete structure is less than 5 cm to avoid corrosion. Iron rods are often joined to a strip foundation, in which the overlap at the joint should be 30 diameters.
If the diameter of the cells is 15 by 15 cm, then they should be laid in 2 layers.
How to convert the weight of a linear meter of reinforcement into tons?
This value is equivalent to 1 m of the product, regardless of height and width. The simplest method for determining linear dimensions is to cut 100 cm of an element from a single piece and determine the mass. To determine how many linear meters are in 1 ton, it is necessary to divide a ton (or 1000 kg) by a certain weight of 1 meter of the required type of metal, based on regulatory documents.
Table of the ratio of weight and linear meter of reinforcement
The number of meters per ton of reinforcement also depends on its diameter. If the reinforcing elements are thin, then the more of them are translated into greater weight. Example: The problem is solved by multiplying the mass and the number of meters.
After mathematical calculations, we obtain kilograms of the material being determined, thus multiplying steel rods Ø 12 mm by a weight of 0.617 kg. As a result, we get 74.04 kg per m. We convert this figure into tons by dividing by 1 thousand: 74.04/1000 = 0.07404 tons.
By performing all calculations in accordance with existing rules, you can accurately determine the amount of reinforcement per 1 m3 of foundation concrete.

Reinforcement weight table per 1 meter
Why might the weight of 1 meter of 12 mm reinforcement be required? For example, when pouring the foundation for a private house, builders can tell you the amount of reinforcement in meters, but at metal warehouses, as a rule, reinforcement is sold and the price per ton is indicated. In this case, knowing the weight of one meter, you can calculate how much reinforcement you will need in tons.
For greater convenience, we have provided a second table, which indicates how many meters of reinforcement are contained in one ton for each diameter.
Here's an example of a calculation:
You need 750 meters of 12mm a500c reinforcement (read: decoding of a500c reinforcement).
We look at the line in the first table corresponding to 12 mm reinforcement; the weight of 1 meter is 0.888 kg.
In total we get 750 * 0.888 = 666 kg.
Weight of 1 meter reinforcement table
Reinforcement diameter (mm) Weight kg/meter| 5,5 | 0,187 |
| 6 | 0,222 |
| 8 | 0,395 |
| 10 | 0,617 |
| 12 | 0,888 |

| 36 | 7,990 |
| 40 | 9,870 |
| 45 | 12,480 |
| 50 | 15,410 |
In industrial construction, a huge amount of reinforcement is used, which is most often supplied in tons. To perform the necessary calculations, you need to know the total length of the existing reinforcement; this can be easily done using the table below.
Calculation example:
You know that you have 25 tons of 10mm reinforcement.
Using the table, we find the number of meters in a ton corresponding to 10 mm reinforcement: 1620 meters.
Total total length of the reinforcement: 25 * 1620 = 40500 meters.

A12 mm fittings: characteristics, distinctive features, how much a linear meter weighs
Reinforcement refers to metal rods, rods or ropes of various shapes and cross-sections intended for construction work to fasten specialized structures. Reinforcement is indispensable in the manufacture of any types of devices made of reinforced concrete in order to enhance its strength.
According to its characteristics, it is divided into strength classes and comes in different diameters, which affects the effectiveness of its use in reinforced concrete building structures. This article will help answer the questions “How many meters are there in a ton of reinforcement?” and “How much does a meter of reinforcement weigh?”
In terms of labor costs in production, the presented rolled metal can be:
- light (with a diameter of up to 12 mm);
- heavy (with a diameter of 12 - 40 mm).
With a steel rod diameter of 12 mm, it is usually called reinforcement 12 ( A12 ) - this is the most popular rolled metal product in domestic construction.
Characteristics of A12 fittings
During the manufacturing process of A12, GOST 5781–82 is strictly observed, and according to its purpose it is classified into prestressed and non-prestressed . Based on the choice of production technology, the following types of fittings 12 are distinguished:
- cold drawn;
- hot rolled
Cold-drawn reinforcement A12 is necessary for the production of reinforced mesh; it is supplied in coils (rolls) of 6-12 meters and is a reinforcing wire.
Hot-rolled A12, being a high-quality type of rolled metal, is produced from steel with a rounded cross-section, and is used in the reinforcement of stressed and ordinary structures, imparts sufficient strength to reinforced concrete structures and prevents damage due to mechanical deformations.
Distinctive features of A12 fittings
These rolled metal products can be made from steel of different grades, which depends on its application and the requirements for its characteristics. Most often, products made from low-alloy structural steel are required. This is due to the fact that such products are easily subjected to arc welding.
The main purpose of A12 is the strengthening of reinforced concrete structures , as well as the formation of frame devices to resist increased loads. A diameter of 12 mm is the minimum for the construction of a strip foundation and its grillages, if you knit a reinforcement frame of four rods. Rentals by class are:
- smooth profile (without corrugation) - class A1;
- periodic profile (with transverse corrugation at an angle to the axis of the rod) - class A3.
This construction metal product is presented from the manufacturer in rods or coils . The scope of its application is very wide.
For the construction of the foundation, it is recommended to use hot-rolled reinforcement in the form of rods with oblique corrugation, the presence of which ensures optimal adhesion to concrete. This interaction of materials ensures the strength and durability of a reinforced concrete building structure.
The transverse arrangement of reinforced rods in the foundation prevents concrete cracking and reduces the force load on the resulting structure, and also protects it from deformation.
Advantages of A12 reinforcement , which are manifested in construction:
- high degree of strength;
- relatively high ductility;
- minimal susceptibility to corrosion;
- high resistance to thermal, chemical and mechanical influences;
- the ability to create various structural configurations by welding and mechanical connections;
- Possibility of use in stressed structures made of reinforced concrete.
There is currently a fairly large selection of grade steel on the construction raw materials market. Recently, there has been a gradual transition, using the example of Europe, to products made from A500C steel instead of the previously popular A400.
This fact, quite logically, is explained by the fact that while fully maintaining the quality characteristics of rolled products, its production cost is reduced by up to 10% due to savings in raw materials during construction operations.
For construction calculations, this amount of expenses is simply colossal.
A special feature of the production of rolled products from this steel grade is the absence of oxidation and, as a consequence, the absence of rust. At the same time, mechanical, chemical and thermal qualities remain at a very high level.
Replacement of steel grade A400 by grade A500C in rolled products makes it possible to reduce its concentration during concreting and, as a consequence, the consumption of A12 reinforcement. The technical characteristics of the steel used do not allow the welds of the finished structure to collapse.
All this leads to increased strength of floors, columns and walls of buildings.
Weight per linear meter of reinforcement 12
For construction work, it is customary to calculate the amount of reinforcement in linear meters, but it is sold mainly by weight.
It turns out that in order to buy the required amount of rolled metal and know exactly its cost, it is necessary to convert the calculated need in meters into weight units, that is, kilograms, tons, etc.
To do this, you can use the table presented . An alternative to the tabular data presented is to independently calculate the data based on the diameter size.
| Diameter, mm | Diameter, m | Weight of 1 meter, kg | Quantity m in 1t |
| 6 | 0.06 | 222 | 4504.5 |
| 8 | 0.08 | 395 | 2531.65 |
| 10 | 0.1 | 617 | 1620.75 |
| 12 | 0.12 | 888 | 1126.13 |
| 14 | 0.14 | 1210 | 826.45 |
| 16 | 0.16 | 1580 | 632.91 |
| 18 | 0.18 | 2000 | 500 |
| 20 | 0.2 | 2470 | 404.86 |
| 22 | 0.22 | 2980 | 335.57 |
| 25 | 0.25 | 3850 | 259.74 |
| 28 | 0.28 | 4830 | 207.04 |
| 32 | 0.32 | 6310 | 158.48 |
| 36 | 0.36 | 7990 | 125.16 |
| 40 | 0.4 | 9870 | 101.32 |
The weight of one meter of reinforced steel is shown in the table as the ratio of the diameter to its weight . Having information about the weight of reinforcing steel, it is possible to determine the coefficient of reinforcement of the structure (the ratio of the weight of rolled metal to the volume of concrete).
In order to calculate the need for reinforcement, you will need data on how many linear meters one ton of rolled metal contains. The number of meters in a ton is a value that depends on several factors. From the presented table it is clearly seen that the footage largely depends on the class of reinforcement.
How many meters are there in a ton of reinforcement 12?
In accordance with building regulations, the amount of reinforcement in a strip foundation as a percentage of the reinforced concrete element in the cross-section must be at least 0.1%. In an example it looks like this.
If the cross-sectional area of the strip foundation is 100*240=2400 square cm, then the estimated number of rolled rods for longitudinal reinforcement is found by multiplying the resulting volume of the foundation by 0.001, that is, 2400*0.001=2.4 square cm.
Next, you should resort to the reference data in the table from the manual on the reinforcement of reinforced concrete elements of monolithic buildings. Since we are interested in reinforcement with a diameter of 12, it is obvious that only 2 reinforced rods are needed for the calculated volume of the foundation. The calculation of the consumption of reinforced steel for a slab foundation is similar.

Reinforcement weight. Weight per linear meter of reinforcement GOST 5781-82
Reinforcement is a set of interconnected elements that, when working together with concrete in reinforced concrete structures, perceive tensile stresses (although they can also be used to strengthen concrete in a compressed zone).
The main application of periodic profile reinforcing steel is in the construction of foundations and walls of buildings and structures made of monolithic concrete. When carrying out concrete work, a significant investment of time and money requires the installation of a reinforced frame to reinforce structures made from reinforcing mesh. To calculate the order volume, you need to know how many kg per meter of reinforcement and the number of linear meters of reinforcing steel.
The weight of a meter of reinforcement is presented in the table of the ratio of diameter and weight of 1 m. Knowing the weight of reinforcing steel according to GOST 5781-82, you can estimate the reinforcement coefficient of the structure (the ratio of the mass of the reinforcement to the volume of concrete) and determine how much material is needed for the foundation (per cube of concrete)
A linear meter of reinforcement is individual reinforcing bars of a smooth and periodic profile 1 meter long, the weight of which depends on the diameter of the reinforcing steel GOST 5781-82 (from a range of diameter sizes of periodic steel - 6, 8.10, 12, 14, 16, 18.20, 22, 25, 28, 32, 36, 40, 45, 50, 55, 60, 70, 80 mm - see RANGE OF FITTINGS).
How much does the reinforcing mesh weigh for screeding, performing plastering work, for making a reinforced concrete foundation frame (concrete + connected reinforcement bars), what is the weight of the reinforcing mesh for brickwork, depends on the size of the cards (length, width of the canvas), the size of the cell (square mm x mm ) and reinforcing wire diameter (mm).
Construction organizations use reinforcement produced in Ukraine, the weight of which meets the requirements of GOST, since domestic reinforcing steel is of sufficiently high quality and complies with all GOSTs and standards for rolled metal.
The weight of the reinforcement is selected depending on the types according to GOST, diameter sizes (see.
table - “Specific gravity of reinforcement in a linear meter”) and the scope of application of the periodic profile.
The weight of a linear meter of reinforcement depends on the shape of the surface of the periodic profile: corrugated or smooth on the outside. Protrusions in the form of ribs, corrugations on the surface of periodically profiled reinforcing steel bars or ribbed wire steel significantly improve adhesion to concrete and its characteristics.
The range of reinforcement, depending on the manufacturing technology of reinforcing steel for reinforced concrete structures, is divided into hot-rolled rod (A1 - A240, A2 - A300, A3 - A400, A500, A600, A800, A1000) and cold-drawn wire steel (VR-1).
The weight of 1 m of hot-rolled reinforcement does not depend on its basic mechanical characteristics, which are divided into six assortment classes depending on the strength of the metal and steel grade, with the symbol: AI, A-II, A-III, A-IV, AV, A- VI.
| Reinforcing steel class | Profile diameter, mm | Reinforcement steel grade |
| AI (A240) | 6-40 | St3kp, St3ps, St3sp |
| A-II (A300) | 10-40 40-80 | St5sp, St5ps 18G2S |
| Ac-II (Ac300) | 10-32 (36-40) | 10GT |
| A-III (A400) | 6-40 6-22 | 35GS, 25G2S 32G2Rps |
| A-IV (A600) | 10-32 (6-8) (36-40) | 80С 20ХГ2Ц |
| AV (A800) | (6-8) 10-32 (36-40) | 23Х2Г2Т |
| A-VI (A1000) | 10-22 | 22Kh2G2AYu, 22Kh2G2R,20Kh2G2SR |
For example, A3 construction reinforcement is used to strengthen concrete structures of prefabricated buildings and is widely used by construction companies in Kyiv. The actual weight of construction reinforcement consists of the mass of the reinforcement frames of the elements (foundation, walls, concrete floors) of a monolithic building, welded mesh, which are then filled with concrete mortar over the formwork.
The production of reinforcing steel in Ukraine is carried out using technologies developed in Soviet times in the field of metal processing, and, as a rule, on equipment inherited from the USSR, and that is why domestic manufacturers sell reinforcing steel at a fairly affordable price with good quality and compliance with GOST requirements .
Reinforcement 8, 10, 12, 14, 16, 18, 20, 22, 25 are the most popular in terms of the diameter of the periodic profile, sold by Ukrainian manufacturers. Imported analogues have a higher price.
Before being sold from metal warehouses, fittings in Ukraine undergo step-by-step quality control during the production process, which guarantees high quality that meets state standards GOST.

Calculation of the weight of reinforcement, welded mesh
If you don’t have a reinforcement calculation table or an online metal calculator at hand, then you can calculate the total weight of the reinforcing mesh yourself by determining the total length of the wire that makes up the welded mesh measuring 1 m2 and multiplying the number of meters by the specific weight of a linear meter of wire.
In the absence of a reference book, you can calculate the weight of a linear meter of reinforcement yourself, using a regular calculator. The volume of metal in 1 meter of a steel cylinder is 1 m x (3.14 x D x D/4) . In parentheses is the geometric area of a circle with diameter D. The weight of the rod is obtained by multiplying the volume by the specific weight of the reinforcement, which is equal to 7850 kg/m3.
Using this method, you can calculate how many kg are in a meter of reinforcement, and convert tons into meters.
For example, using a calculator, we will calculate the weight of 1 m of reinforcement with a diameter of 12 mm: Volume of metal - 1 m x (3.14 x 0.012 m x 0.012 m/4) = 0.00011304 m3,
Specific gravity - 0.00011304 m3 x 7850 kg/m3 = 0.887 kg. Approximately equal to the value in the table of reinforcement with theoretic weight.
If the length of the reinforcement is 12 m, then we substitute the required value of the rolled steel length into the formula and calculate the weight of the rods. To determine the weight of the mesh, you need to multiply the resulting mass of 1 m2 of mesh by the number of square meters in the welded reinforcement frame.
One more example. Let's calculate the weight of a 100x100x4 mesh with an area of 1 m2. The welded mesh consists of 18 welded reinforcing bars 1 m long. The total length of the rods will be 18x1=18 meters. The specific gravity of 4mm reinforcing wire is 0.092 kg/m. Then the mass of a linear meter of mesh with a height of 1 m will be 18x0.092 = 1.66 kg/m2 + 1% of the mass of welding materials.

Number of meters and pieces of reinforcement in 1 ton: calculations and tables
14.04.2019
The number of meters and pieces of reinforcement in 1 ton depends on the diameter of the rod used. It is necessary to know this when purchasing material, so that you can independently check the quantity of goods supplied, as well as calculate the volume of reinforcement for reinforcing monolithic structures.
Footage of reinforcement in ton: calculation example, table
Let's look at an example of how the calculation is made and find out how many meters of reinforcement with a diameter of 12 mm are in 1 ton.
To calculate, we need to know the mass of 1 meter, look at the table of the weight of the reinforcement, it is equal to 0.888 kg. Now we divide 1000 kg by 0.888 kg, we get 1126.13 m. For convenience, below is a table that immediately indicates the footage of the most popular steel rods in construction.
| Rod diameter, mm. | Number of meters in 1 ton |
| 6 | 4504,5 |
| 8 | 2531,65 |
| 10 | 1620,75 |
| 12 | 1126,13 |
| 14 | 826,45 |
| 16 | 632,91 |
| 18 | 500 |
| 20 | 404,86 |
| 22 | 335,57 |
| 25 | 259,74 |
| 28 | 207,04 |
| 32 | 158,48 |
| 36 | 125,16 |
| 40 | 101,32 |
| 45 | 80,13 |
Knowing how many meters are in 1 ton, you can easily convert the reinforcement from meters to tons. For example: we will convert 8956 m of rods with a diameter of 12 mm into tons. For this, 8956/1126.13=7.953 (t). In this way, any size of whip can be converted by simply dividing the total length by the length of 1000 kg.
Number of reinforcement pieces per ton: calculation example, table
Knowing the footage of the rods in 1000 kg, you can make calculations by the piece. Let’s also look at how to do this using an example, let’s calculate how many pieces of 12 mm reinforcement are in 1 ton, 12 m long and 11.7 m long (the most common lengths produced by factories).
To calculate the number of pieces, we take the total footage in one ton, for rods 12 mm long, it is equal to 1126.13 m, and divide by the length of the rod 12 m, we get 93.84 pieces, for a rod 11.7 m long, the result is 96.25 pieces .
The table below shows the number of whips of the most common sizes (calculated values are rounded to the nearest tenth).
| Diameter of fittings, mm. | Number of pieces per ton of rods 11.7 m long. | Quantity for rod length 12 m. |
| 6 | 385 | 375,4 |
| 8 | 216,4 | 211 |
| 10 | 138,5 | 135 |
| 12 | 96,2 | 93,8 |
| 14 | 70,6 | 68,9 |
| 16 | 54,1 | 52,7 |
| 18 | 42,7 | 41,7 |
| 20 | 34,6 | 33,7 |
| 22 | 28,7 | 28 |
| 25 | 22,2 | 21,6 |
| 28 | 17,7 | 17,2 |
| 32 | 13,5 | 13,2 |
| 36 | 10,7 | 10,4 |
| 40 | 8,6 | 8,4 |
| 45 | 6,8 | 6,7 |
An example of a calculation using a table: let’s say for reinforcing aerated concrete blocks and an armored belt, you need 600 kg of 10 mm reinforcement. In order to make it convenient to transport, 12 meter rods were cut into 6 m lengths. To find out their number, take the table value of 135 (pieces per ton) and multiply by 0.6, equal to 81 pieces. Since they were divided in half, we multiply 81 by 2, we get 162 rods of 6 meters each.
Do not forget that when cutting reinforcement into short rods, its consumption for reinforcing the structure increases, since more overlaps will have to be made. It is worth taking this into account when calculating and purchasing materials for construction.
According to these tables, you can calculate the required tonnage of rods for reinforcing a strip foundation, monolithic belt and other reinforcing structures, based on the footage of the building. And also, you can calculate for yourself whether the material was brought to you correctly by recalculating its quantity.

How many pieces of reinforcement in a ton
Reinforcement is an indispensable building material that is used in various types of work to ensure the strength of structures.
When purchasing this material, you are immediately faced with the fact that when selling reinforcement, its weight component is taken into account, and manufacturers provide prices in tons.
When calculating construction and installation work, where this material is in demand, it is necessary to enter a value in meters, which will allow you to determine the required amount of reinforcement. The problem arises of determining how many pieces of reinforcement are in a ton in order to determine the required quantity.
Features of calculation of construction reinforcement
Being one of the types of long-rolled metal products, fittings are made from the appropriate grade of steel using the hot-rolled method. Reinforcement is the basis of any reinforced concrete structure. With its help, the frame of such products is formed and the foundations for heavy objects are strengthened.
The durability of buildings, their strength and reliability, and prevents the possibility of deformation, depend on its quality and characteristics.
Inside structures, reinforcement can be placed in two ways: • if it is necessary to create resistance to tensile forces and stress, which prevents the possibility of cracking, longitudinal placement is used;
• transverse – for binding concrete under high pressure and protecting it from the appearance of cracks in an inclined direction.
Easily welded, it allows the formation of any structural shape. The importance of this material cannot be ignored and the lack of replacement by any other type makes its use in construction mandatory.
Formulas for calculating the consumption of reinforcement when creating certain structures, carrying out reinforcing and strengthening work in construction take into account the footage and diameter of this building material. Most often, production provides construction with A500S reinforcement of four main diameters - 10 mm, 12 mm, 14 mm, 16 mm.
The fittings are offered for sale by weight. Therefore, in order to find out how many pieces of reinforcement are in a ton, it is necessary to convert the linear footage into a weight equivalent. The number of meters here depends on the diameter of the product.
When determining the number of reinforcements using the formula, you will need to take into account the presence of such a dependence - reducing the diameter increases the footage per ton.
How many meters of reinforcement are in one ton
Steel reinforcement is the most common type of rolled metal. It is used in the construction of various types of structures using reinforced concrete to increase the strength of concrete. Basically, the fittings are made of hot-rolled round steel with a round or periodic profile. Such reinforcement is mainly used for reinforcing walls and floors in monolithic buildings.
After all, the purpose of reinforcement is to reinforce or increase the stability of a reinforced concrete structure, which is prestressed or conventional. It gives reinforced concrete structures additional strength and protects against possible deformations.
There are two options for placing bar reinforcement inside a reinforced concrete structure: longitudinal regulates tension and stress, reducing the risk of cracks, and transverse is designed to reduce the risk of inclined cracks and binds the concrete in the compressed zone.
How many pieces of reinforcement are there in a ton?
Most often during construction, reinforcement of different diameters is used, especially 10 mm, 12 mm, 14 mm and 16 mm steel grade A500C. When calculating how many pieces of reinforcement per ton need to be used for the construction of the foundation, its quantity is calculated in linear meters, that is, after the calculation it becomes clear how much reinforcement is needed to reinforce the structure.
But when selling, the measure of the amount of reinforcement is considered to be tons, not meters, therefore, to determine the final cost of the amount of reinforcement required for construction, it is necessary to convert linear meters of reinforcement bars into tons and then look at the price.
How many meters in one ton of reinforcement will depend on the diameter of the reinforcement itself: the thinner it is, the more meters there are, respectively, in a ton.
In order to determine the exact weight of the reinforcement based on its length, you first need to know its diameter. Therefore, before starting construction, you need to accurately determine the type of profile of the metal product.
For example, for reinforcement with a rod diameter of 6 mm, the weight will be 0.222 kg per meter, for reinforcement d 8 - 0.395 kg, for reinforcement d10 - 0.617 kg per meter, for reinforcement with a rod diameter of 12 mm, the weight of one meter will be 0.888 kg, for fittings d14 – 1.210 kg, for fittings with diameter d16 – 1.580 kg, for d18 – 2.000 kg and for d20 – 2.470 kg.
To calculate the required amount of reinforcement, it is necessary to know not only the diameter of the steel used, but also its dimensions, and take into account the requirements for restrictions in use and technological processes.
Therefore, to calculate in detail how much reinforcement is in a ton, a special program is often used, for which you must first know the basic parameters it needs to carry out mathematical operations.
Then it gives the result: how many linear meters in one ton of reinforcement will be used for a specific construction project.
Of course, everything would be much simpler if the fittings on the market existed in only one form. And since the thickness of each type of profile is different, the calculation of how many pieces of reinforcement are in a ton of profile will be different each time, and the total value of the quantity will be inversely proportional: the thinner the reinforcement bars, the more meters and the more pieces there will be in one ton.

Types of reinforcing bars and their main characteristics. Reinforcement weight table
Construction fittings (rolled reinforcement or rolled metal) is a metal rod of a certain diameter and length, made from steel of various grades in accordance with the requirements of the standard.
In the Russian Federation, the document regulating the amount of reinforcing steel in reinforced concrete structures is SP-52-101-2003 and GOST-57-81-82.
For the common man, the weight of reinforcement can be determined using special tables located in these standards, as well as in construction reference books.
Basic design requirements for reinforced concrete structures. Weight of size 12 fittings
In order for reinforced concrete structures used for the construction of individual residential buildings to be reliable and durable, designers and builders must follow a number of basic rules. These rules govern the use of reinforcement in various reinforced concrete structures:
- For beams. The minimum diameter of longitudinal working metal products in reinforced concrete floor and roof beams, lintels and girders must be at least 12 mm, the maximum diameter is no more than 32 mm, the optimal diameter of reinforcing bars in reinforced concrete beams is 12-20 mm.
- For columns. In reinforced concrete columns, the minimum permissible diameter of the longitudinal working reinforcing bars is 14 mm, the maximum is 36 mm. The minimum number of working rods in a column is 4 pcs. The specific gravity of reinforcement in a reinforced concrete column should be less than 10% (and in beams - 8%).
- For foundations. In reinforced concrete foundations, the smallest diameter of working reinforcement should be 10 mm. Maximum – not limited. The most common diameters of reinforcing bars in the construction of individual houses are 10-16 mm.
The reinforcement can be wire (3-6 mm in diameter) and rod (8-40 mm in diameter). Rod reinforcement is also called flexible. In particularly loaded and critical structures, rigid metal products (rails, angles, I-beams, pipes) are used.
Reinforcement 12, whose weight is insignificant, has proven itself best in reinforced concrete structures. It is believed that measured reinforcing bars are more effective when laying concrete. Reinforcement 12 with a weight of 888 grams per meter can be produced in rods with a factory length of 11.48 m. This will reduce welding costs (when welding rods).
reinforcement weight table
A few words about the available reinforcement weight tables
According to GOST-57-81-82, the profile number, the weight of the reinforcing steel, as well as its cross-sectional area and maximum mass deviations must comply with Table 1 given on our website. Experts have also developed numerous reference books on rolled metal products.
Some of them indicate the chemical composition and properties of rolled products, the level of weldability and hardening, and the weight of 1 meter. Useful for storekeepers and suppliers is a directory of various types of metal, where several pages are occupied by tables of reinforcement weights.
By the weight of 1 m of reinforcement, you can determine the need for tonnage and, conversely, how many meters of reinforcement are per ton of this rolled product.
The weight of 1 m of reinforcement affects the total tonnage of the batch
In rolled metal, calculations are mainly carried out in tons or kilograms. Metal suppliers are well aware of the reinforcement weight tables. Guided by them and the need for meters, they order the required quantity in tons. It is advisable to order a batch of metal equal to the weight of the bundle formed at the factory.
Managers and storekeepers are familiar with how much one shipment weighs and will inform the consumer about this. For example, when receiving reinforcement 12th, weighing 3 tons, it is recommended to pay and purchase 3200 kg or 2800 kg of this rolled product, so as not to tear the existing packaged packs.
Of course, if the customer absolutely needs 3 tons, and no less and no more, then a few free rods from the torn packaging can be added to the finished package of 2.8 tons. But during transportation, such a loose and relatively light rental can simply be lost, or part of it can be pulled out in the parking lot.
Based on the fact that the weight of 1 m of 12th reinforcement is 888 grams, one 9-meter rod of such metal products weighs about 8 kilograms. It can be easily lifted by an ordinary man.
For the finished batch of 2.8 tons of reinforcing bars, the warehouse will provide another 25 bars. They must be additionally packaged, tied with binding wire. Typically, experienced suppliers and delivery managers prefer to deal with packaged rolled metal products. If there is a discrepancy in weight indicators, the customer will be refunded, and if there is an excess of metal supplied, which is allowed in rare cases, the customer must pay extra.
When working with metal, you should remember that metal is not sausage, you can’t just cut a couple of kilograms from it. Although, with the current high cost of rolled metal, many wholesale metal warehouses and stores provide metal cutting for an additional fee. But such a procedure is not always justified. Construction reinforcement is not exactly a metal that requires cutting.
The cost of the weight of 1 m of reinforcement will be approximately equal to the cost of cutting, which is neither rational nor effective.
The use of various classes of reinforcement in construction
The class of reinforced metal products is one of the main indicators of its quality (tensile strength). The classes are designated A and B. These categories must meet all existing standards and requirements (yield strength, weldability, ductility, cold resistance, etc.).
In the construction of reinforced concrete structures, smooth rolled metal of class A 240 is used. Also in the construction of reinforced concrete structures, classes A 300, A 400, A 500, B 500 can be used, which refer to a periodic profile (reinforcement with characteristic transverse protrusions and longitudinal ribs).
Depending on the type and physical properties of reinforcing steel, it is used for:
- construction of reinforced concrete structures
- laying foundations and strengthening concrete structures;
- production of reinforcing mesh;
- construction of frames, fences, etc.

Reinforcement weight 12 mm per meter table
Appearance of fittings.
When knitting frames, meshes, as well as when constructing a foundation, the main element is reinforcement. As for private construction, one of the most in demand here is rolled metal with a diameter of 12 millimeters. The favorable ratio of strength and affordable price allows you to use 12 mm reinforcement in the construction of a private house.
Why do you need to know the weight of rolled metal? This value will be needed to estimate the cost of construction work at different stages. Usually the weight is already calculated in the project for each structure where rolled metal A12, A3 or any other grade is used.
If you plan to do the construction calculations yourself or just want to understand this point in detail, then this material will answer all your questions.
After studying the article, the reader will be able to independently carry out calculations and find out the weight of reinforcement 12 mm, A3 or another brand.
Weight calculation
The calculation is performed in linear meters - special quantities usually used in construction work. The table also shows the weight of one linear meter. At the same time, reinforcement is sold by weight, and not by length. The builder's task is quite simple: find out how many meters are required for all structures, and then convert them into units of mass. Below is a detailed and simple table that will help you find out the weight of one linear meter. Weight calculation
In this table you need to find the required diameter (D), in this case it is 12 mm. The second column shows D - this data is not particularly needed, and converting 12 mm is quite simple (you need to divide 12 mm by 100, the result is 0.12 m).
The third column of the table is the most important - the mass m per kg is indicated here. A meter of rolled metal equals 12 millimeters to 0.888 kilograms. Also, as an example, you can take 10 mm rods, the weight of which is 0.617 kg.
The last column shows how many meters there are in one ton.
Calculator
Self-calculation
Now the reader knows how much one meter weighs. But in order to better understand the work, you need to understand the scheme by which the calculation is carried out. Having understood the essence, the builder will be able to calculate the weight of one linear meter of rods with a diameter of 12 or 10 mm.
To perform the calculation, you must proceed according to the following scheme:
The volume of one linear meter can be obtained using the following formula: 1m x (0.785 x D x D). Here the letter "D" represents the diameter of the circle. The total mass is multiplied with the specific gravity of the rods; in all cases it will be 7850 kg/m3.
To find out how much a meter weighs, you need to know the volume.
For example, you can independently calculate the mass of one meter of 10 mm reinforcement. The first step is to obtain the volume - 1m x (0.785 x 0.010 x 0.010) = 0.00010124 m3. The mass of rods is 10 mm – 00010124 m3 x 7850 = 0.616 kg. If you look at the table, one meter of reinforcement 10 weighs 0.617 kg. How much a meter of rods 14 or 16 weighs can be found using the same scheme.
Number of meters in one ton
A more detailed table, where the steel class is also present.
Above is the calculation for 10 mm. The number of meters per ton can also be calculated without using specialized tables. Here it is worth referring to the building regulations, which state that the strip base must contain at least 0.1% of rods in relation to the reinforced concrete structure. This formulation looks quite complicated.
To understand how this works, it’s worth looking at an example:
- A strip base is taken, the area of which is 2400 square cm.
- Next you will need a coefficient, for this formula it is 0.001.
- The resulting volume is multiplied with a coefficient - 2400 x 0.001 = 2.4 cm2.
- At the next stages, you won’t be able to do without reference information. Here you will need a manual that indicates the required number of rods.
For reinforcement with a diameter of 10 and 12 mm, two rods are sufficient.
What you need to know about A12 fittings
Rods are made from steel, the grade of which depends on the requirements for strength, wear and other parameters. Typically, builders choose rods made of low-alloy metal. It cannot be said that this is the most reliable and durable steel, but it does have an important advantage - low-alloy metal can be processed using arc welding.
Grade A12, like reinforcement with a diameter of 10 mm, is usually used to add strength to a structure made of reinforced concrete. Also, these rods are the main element in the construction of frame structures. In addition to this parameter, you also need to pay attention to rental, it differs by class:
- Periodic profile – A3. Class A3 fittings have transverse corrugation.
- Smooth profile – A1. Unlike A3, class A1 fittings come without corrugation.
You can purchase reinforcement, regardless of diameter or class A3, in coils or rods.

Reinforcement - table of weight and number of meters in 1 ton
Today we will talk about how much the reinforcement weighs, and the maximum length of a metal rod. Mostly about how many meters are in a ton of reinforcement, but other diameters will also be considered.
Weight of reinforcement, how many meters in 1 ton?
During construction, it is necessary to have an accurate idea of how much weight the entire reinforced structure has as a whole. There are a number of reasons for this:
- This makes it possible to withstand reinforcement technology.
- Guarantees the necessary reliability of the structure.
- It is more convenient to calculate the total cost of the structure.
The greatest attention is paid to a rod with a diameter of 12 mm, because this is the minimum diameter that can be used when creating structures for strip foundations. And of course, we should not forget about the significant factor that during construction, it is very important to know exactly how many meters of reinforcement will be required for one ton of planned products.
How much does the reinforcement weigh and the amount of reinforcement per ton, table:
The weight of a meter of reinforcement is presented in the table of the ratio of diameter and weight of 1 m. Knowing the weight of reinforcing steel according to GOST 5781-82, you can estimate the reinforcement coefficient of the structure (the ratio of the mass of the reinforcement to the volume of concrete) and determine how much material is needed for the foundation (per cube of concrete)
A linear meter of reinforcement is individual reinforcing bars of a smooth and periodic profile 1 meter long, the weight of which depends on the diameter of the reinforcing steel GOST 5781-82 (from a range of diameter sizes of periodic steel - 6, 8.10, 12, 14, 16, 18.20, 22, 25, 28, 32, 36, 40, 45, 50, 55, 60, 70, 80 mm).
