How many rods of 14 rebar are in a ton

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 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
14	1,210
16	1,580

20	2,470
22	2,980
25	3,850

32	6,310
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.

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.

How much reinforcement per ton in linear meters

Every person who is building his own house or just planning construction work often asks the question: “How much reinforcement in meters is there in a ton?” This question is natural, since all calculations for this product at the construction site are carried out in meters, and when purchased - in tons.

Types of fittings

Before looking for the answer to the question: “How much reinforcement in meters is there in a ton?”, you need to clearly understand what kind of material it is and what the nuances of its use are.

Along with classic steel reinforcement, fiberglass reinforcement is now widely used. This is a fairly new material on the Russian building materials market. Therefore, many people prefer steel, since it has already been tested for decades.

For various types of work, depending on the need, reinforcement of various diameters (from 0.6 to 4 cm) can be used. Another difference is the presence of special ribs on the outer part of the rod. They are necessary to securely fix it in concrete.

Application of fittings

Almost no modern construction can do without reinforcement. The main purpose of this building material is to reinforce concrete structures:

• Foundations and piles.
• Floors.
• Floors.
• Window and door lintels.
• Foundation blocks and more.

To reinforce floors, foundations, piles of other concrete structures that carry significant weight, rods with a diameter of 1.2 to 4 cm are used. In private house construction, a thickness of 1.2-1.4 cm is sufficient for foundation work. For floor reinforcement in In a private house, thinner reinforcement (6-8 mm) is most often used. Now you can move on to calculating how much reinforcement is in meters in a ton.

Weight calculation

So how many meters of reinforcement are in 1 ton? The answer to this question depends, first of all, on the material from which it is made (fiberglass, steel) and the diameter of the product. For calculations, we will take the dimensions most used in private construction.

So, the ratio of the diameter and weight of one linear meter of a steel product:

Diameter, cm	Weight per meter, kg	Number of p. meters in 1 ton
0,6	0,22	4505
0,8	0,4	2532
1,0	0,62	1621
1,2	0,89	1126
1,4	1,21	826
1,6	1,58	633

How many meters of fiberglass reinforcement are there in a ton? One of the main advantages of this type of material is its relatively light weight. Another advantage of fiberglass reinforcement is its ease of transportation. It can be transported in a passenger car, as it is lighter and more flexible (it is rolled up into axle boxes in production).

Diameter, cm	Weight per meter, kg	Number of p. meters in 1 ton
0,6	0,05	20400
0,8	0,08	12195
1,0	0,13	7462
1,2	0,19	5405
1,4	0,28	3623
1,6	0,35	2841

Reinforcement: weight per linear meter, formulas and calculation examples

In the total cost of construction, a significant portion falls on the reinforcement of reinforced concrete structures. In retail sales, the price is per linear meter. However, when constructing a foundation, a large amount of reinforcement is required, so it is cheaper to purchase it at wholesale stores. And the wholesale price is indicated in rubles/ton of products. This means that linear meters must somehow be converted into tons.

State standards indicate the weight of one linear meter of reinforcement of a specific diameter. To calculate the required kilograms or tons, you need to multiply the weight of one meter by the total length of all rods of the same diameter. By weight, by the way, the percentage of reinforcement of a reinforced concrete structure is also determined (the ratio of the mass of metal and the volume of concrete).

How to use the table

The table shows:

• Reinforcement diameter
• Sectional area of ​​the rod
• Weight of one linear meter
• Steel grade

First, in the “diameter of reinforcement” column, you find the product with which you are going to reinforce the structure, then, moving along the horizontal line of the table, you look for the weight of a linear meter.

Table - weight per linear meter of reinforcement

If you don't have a table at hand

Not everyone has the necessary GOST, but each of us studied at school. To independently calculate the weight of a linear meter, basic knowledge of mathematics and physics is sufficient. Everyone knows that mass is equal to the volume of a body multiplied by the specific gravity of the material. The volume is calculated using the formula:

V = F x L, where

• V – body volume, m3
• F – its cross-sectional area, m2
• L – body length, m

The cross section of the reinforcement is a circle. Its area is easy to calculate, knowing the diameter of the rod:

F = 3.14 x D2/ 4 = 0.785 x D2, where

• D – reinforcement diameter (in meters)
• 3.14 – the well-known constant value π (it is dimensionless)

As you can see, calculating the cross-sectional area and volume of the rod is not difficult. Now you can calculate the weight of a linear meter. This is also done simply, using the formula:

M = V xp, where

• p – specific gravity of steel. It is equal to 7850 kg/m3.

There is some inaccuracy in these calculations: the reinforcement is not a smooth rod, and we do not take into account the dimensions of the corrugations. But if you calculate the weight of a meter rod in this way and compare it with the tabular data, you will see that your result is not much different from them.

Calculation examples

As examples, let us consider calculating the weight of a linear meter of reinforcement with the most common diameters of 6 mm and 12 mm of class A III. This material has a periodic profile (longitudinal ribs and transverse protrusions are applied to its forming surface). Special steel is used to manufacture A3 reinforcement. Thanks to the complex surface, metal and concrete form a single monolith.

Reinforcement with a diameter of 6 and 12 mm is used in the construction of dachas, private houses - for reinforcing strip foundations.

• Let's calculate the weight of a linear meter of A3 reinforcement with a diameter of 6 mm:
  • Sectional area F = 3.14 x 0.006 x 0.006/ 4 = 0.000028 m2
  • Volume per linear meter V = 0.000028 m2 x 1m = 0.000028 m3
  • Weight M = 0.000028 m3 x 7850 kg/m3 = 0.221 kg

• Let's calculate the weight of a linear meter of reinforcement with a diameter of 12 mm:
  • Sectional area F = 3.14 x 0.012 x 0.012/ 4 = 0.000113 m2
  • Volume per linear meter V = 0.000113 m2 x 1 m = 0.000113 m3
  • Weight M = 0.000113 m3 x 7850 kg/m3 = 0.887 kg

According to the GOST table, weight is 1 linear. m of reinforcement 6 is 0.222 kg, reinforcement 12 is 0.888 kg. As you can see, the discrepancy in numbers is small. It must be admitted, however, that the data presented in the table also does not claim to be highly accurate. They were also calculated theoretically.

In fact, the actual weight of a linear meter may differ from the table by 0.2 - 3%, both plus and minus.

The video shows examples of calculating the weight of reinforcement, and also shows the calculation process in an online calculator.

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).

Reinforcement size (nominal bar diameter)	Weight of 1 m of reinforcement, theoretical, kg	Number of meters of reinforcement in 1 ton, m.
4	0,099	10101,010
5	0,154	6493,506

60	22,190	45,065
70	30,210	33,101
80	39,460	25,342

Judging by this table, 1126 meters of reinforcement with a diameter of 12 mm equals one ton of product.
Using this table you can also find out the length of the reinforcement in one kilogram and its weight in one meter of all sizes.

These values ​​will be useful to you when using a metal rod directly if, for example, you need to know what the mass of all the reinforcement used in the construction of a building is. To do this, you just need to add up all the lengths of the reinforcing bars and then multiply the sum by the weight of 1 p/m.

It should be noted that 10 mm reinforcement still exists and is used when pouring foundations.
But this occurs only in transverse, that is, in auxiliary reinforcement. In addition to these factors, we should not forget that only those rods that are marked with the symbol “C” are subject to welding. This whole long process is necessary, since during construction it is necessary to know the length of the reinforcement, and when purchasing it, mass (weight) is important.

Diameters of fittings according to GOST 5781-82

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.

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).

 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 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

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.

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:

1. A strip base is taken, the area of ​​which is 2400 square cm.
2. Next you will need a coefficient, for this formula it is 0.001.
3. The resulting volume is multiplied with a coefficient - 2400 x 0.001 = 2.4 cm2.
4. 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.
