How many bars of reinforcement 16 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, weight table (weight) per 1 meter of reinforcement

When carrying out construction and installation work, calculating the mass of metal products is extremely important, since it allows you to estimate the final parameters of the structures being built and determine the cost of the material (for this, the weight of the reinforcement is taken to be 10 mm per meter).

To carry out calculations, you can use special tables that indicate the parameters of the rods and their estimated weight, as well as popular online calculators, for the use of which you need to know the exact data on the technical characteristics of rolled metal.

Knowing the exact weight of rolled materials, you can save a lot by choosing the right vehicle to transport them. If you are not sure that you can make the calculations correctly, the Regional House of Metal company will help you find out the weight of 12 mm reinforcement per meter with extreme accuracy, since they will calculate it using a special formula. View available types of foundation reinforcement.

Rebar weight table

You can find out what mass the product has - reinforcement 12 weight 1 meter - from the tables that indicate:

weight of one linear m of product;
number of rolled meters in one ton;
rolled diameter in millimeters;
cross-sectional area of the rods in square centimeters;
class of steel used in production.

In most cases, using a table, you will be able to find the desired value. If the table did not help determine the weight of 16 mm reinforcement per meter, you can resort to using an online size calculator to make calculations. To use it, you need to know the following parameters: rolled diameter, rod length and number.

The calculator will calculate the total mass for one rod, the total length of the rods, and the volume in cubic meters. There are also calculators that rely on reference data for calculations. To use them, you need to know the GOST according to which the rolled products are manufactured, the material of manufacture and the assortment (name of the rolled products).

There are also products for which this tool is not suitable, one of such products is masonry mesh, the page of which can be found here.

Weight of reinforcement

What to do if you don’t have an online calculator at hand, and you don’t really trust the data from tables on the Internet? It’s simple - you can determine the weight of 8 mm reinforcement per meter yourself using the most common calculator.

To find out the mass of a linear meter of rolled metal, you need to determine the total length of the rods, and then multiply the specific gravity of a linear meter of the product by the number of meters. The formula used for calculation is: 1 m x (3.14 x D x D/4). By performing the actions in brackets, we obtain the geometric area of a circle with a given diameter.

Did not you find what you were looking for? You may be interested in the page with pipeline valves, which can be found here: http://rdmetall.ru/truboprovodnaya-armatura/zatvory/.

Thus, we obtain the weight of a linear meter of reinforcement by multiplying the volume by the specific gravity of the product, equal to 7850 kilograms per cubic meter. An example of calculations for one m of a rod with a diameter of 8 millimeters.

Metal volume: 1 m x (3.14 x 0.008 m x 0.008 m/4) = 0.00005024. Specific gravity: 0.00005024 cubic meter x 7850 kilograms per cubic meter = 0.394384 kilograms.

You can substitute any value of D into the formula and obtain accurate data for any rolled metal, which will allow you to determine the cost of structures for construction.

The main value by which the amount of reinforcement is determined is its nominal diameter (d), regardless of whether the surface is smooth or with various types of corrugation. There is an option in which right and left entries are made on opposite sides of the rods to improve adhesion to concrete (used for high-strength steels).

The latter has the form of cylindrical rods with transverse protrusions formed along a helical line and two longitudinal ribs. Calculation of the number of meters of reinforcing bars in 1 ton. For foundations, reinforced concrete structures, and gas-block houses, round and periodic steel is used. This information is needed to determine the weight and cost of the structure, as well as for the correct organization of work during purchase and delivery to the construction site.

According to GOST 5781-82, hot-rolled reinforcement A240 - A1000 is produced (the letter A denotes the production method, and the number denotes the yield strength in MPa): In accordance with the standards, the cross-sectional areas of a periodic profile (non-circular) and having the shape of a circle of the same diameter are identical.

This problem arises due to the fact that the results of strength calculations for rods are presented in meters, but to buy them, data in tons is needed. The answer to the question, how many meters of reinforcement are in 1 ton, is of interest to both designers and builders.

Consequently, their masses per 1 meter are also equal.

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).

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 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

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.

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:

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
6	0,222	4504,504

40	9,870	101,317
45	12,480	80,128
50	15,410	64,892
55	18,650	53,619
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.

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.

Reinforcement weight. Weight per linear meter of reinforcement GOST 5781-82

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.

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).

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).

Reinforcing steel class	Profile diameter, mm	Reinforcement steel grade

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

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.

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

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.

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.

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.

Reinforcement length: standardized parameters and popular options

The construction of reinforced concrete structures is not complete without reinforcement. It ensures the creation of a strong frame that contributes to the elasticity of concrete. When creating a project, builders must calculate the volume of source material, including reinforcement. Its consumption depends on the length of the rod. What types of reinforcement exist, what length is considered standard and how to calculate the number of rods for the foundation.

Steel reinforcing bars

Types of rod reinforcement and their features

Rod reinforcement is divided into varieties in relation to the material used for the manufacture of elements. There is steel and composite. Steel reinforcement is classified into three categories based on production technology, purpose of use and alloy composition:

Hot rolled - used for ordinary products, prestressed materials and reinforced concrete structures (GOST 5781-82);
Thermo-mechanical - the manufactured rods are characterized by a high strength index and are used in reinforced concrete structures (GOST 10884-94);
Weldable rods - suitable for reinforced concrete structures and products (GOST 52544-2006).

The composite type (GOST 31938-2006) is divided into two subtypes:

Plastic AKS - made from glass roving compound obtained by polymerization of epoxy resin
Basalt-plastic batteries - basalt-based polymers are used in production.

Basalt plastic materials are losing popularity in the market. Customers prefer to choose polymer plastic glass products.

Steel reinforcement, unlike fiberglass elements, is susceptible to corrosion, which reduces its service life. And also due to its greater weight, consumers prefer to refuse it.

Fiberglass ones are almost as expensive as steel products. Their lighter weight makes them easy to transport. Such fittings do not form corrosive compounds and do not react with alkalis, acids, or sea salt. But such elements are not subject to bending and eliminate the use of welding during installation. Steel types are stronger, but allow the rod to bend, which makes it easier to arrange a strip foundation.

Factors influencing the size of the reinforcement are:

Standardized norms approved at the state level;
Customer's wishes;
Manufacturer's decision;
Generally accepted dimensions of other products used in construction.

Primary steel reinforcement or composite materials are produced taking into account state standards. They, in turn, allow various errors when forming individual parties.

Length of rod reinforcement - all possible options regulated by GOSTs

Lengths of 12 m are more common on the market. But you can order longer rods with a length of 26 m. The length of the reinforcement varies in different ranges relative to the established GOST.

GOST 5781

The nominal value is 6-12 mm. The standards allow for deviations associated with the delivery of products in batches. There are 3 types known:

The rods in the entire batch have a measured length;
There are unmeasured segments in a measured batch;
Party with unmeasured length.

If the batch is measured, then the length of the rod reinforcement is equal to a certain figure, which is included in the segment 6-12 mm. The customer or manufacturer chooses the desired length.

The fittings are delivered to the customer in this form.

In the presence of unmeasured segments (option 2), their length is at least 2 m. The total number of unmeasured segments does not exceed 15% of the mass of the entire batch.

Unmeasured batches are characterized by the presence of reinforcement with a length of 3-6 m. The percentage of rods is no more than 7%.

The standard does not exclude cases of supply of rods with a length of 5-25 m, when the customer and supplier previously agree on the dimensions of the products. GOST provides for maximum size deviations when cutting rods:

Rods up to 6 m – deviation with normal accuracy +50 mm, and with increased accuracy +25 mm;
Rods over 6 m - the length of the rods with normal accuracy deviates from the norm by 70 mm, and with increased accuracy by 35 mm upward.

Increased accuracy is observed in a situation where the customer requires production of the required length.

GOST 10884

The standard regulates the production of rods with a diameter of at least 10 mm. The length of the rod reinforcement ranges from 5.3-13.5 m. The standards provide for the production of products with a length of up to 26 m, when the delivery conditions are agreed with the consumer.

Weldable reinforcement belonging to class “C” is also produced in other length options. Lots may hold pieces of other lengths in accordance with the rules:

Unmeasured rods in measured deliveries are produced with a length of more than 2 m and in an amount of 15% of the total mass of the batch;
Unmeasured lots, in which the rods correspond to a length of 6-12 m, but it is possible to have segments of 3-6 m in a percentage of no more than 7% of the total weight of the lot.

GOST is characterized by deviations from standard values with normal and increased accuracy. The errors correspond to the values from GOST 5781 (described above).

GOST 52544-2006

The length of the fittings of this standard can vary between 6-12 m. The produced batches are divided into 2 types:

Measuring – standard rods 6-12 m long, the length of which is agreed with the customer;
Unmeasured - the length of the rods is selected by the manufacturer in the range of 6-12 m; the presence of shortened rods of 3-6 m is allowed in an amount of no more than 7% of the total mass of the batch.

The deviation error from standard dimensions cannot be more than 100 mm upward.

GOST 31938

The length of polymer-type fittings varies from 0.5 to 12 m. This is the standard size for measured batches. A dimensional step of 0.5 m has been approved, used in the manufacture of rods of other lengths. The standard does not exclude other variations, the length of which is greater than the established value.

Permissible deviations for the length of measuring rods:

0.5-6 m – 25 mm in the larger direction;
6-12 m – 35 mm more;
More than 12 m - the error is +50 mm.

Since the plastic type is widely used in the construction of large objects in extreme conditions, manufacturers offer delivery in coils.

Sizes 12 fittings

A common option for constructing building structures made of reinforced concrete is reinforcement 12, which has a diameter of 12 mm.

Possible diameters of fiberglass reinforcement

It is made from various steel alloys. The diameter of this type meets the minimum requirements for the construction of buildings on a strip foundation when knitting a frame of 4 rods.

IMPORTANT! The most significant condition when constructing a foundation is considered to be the laying of reinforcement along a side of more than 3 m. The minimum diameter of the rods must be at least 12 mm.

Rolled products are grouped into classes regarding mechanical properties:

A1 Smooth profile - has good ductility, which is required during elongation, providing stretching;
A2 with a crescent pattern - thanks to the pattern, strength increases;
A3 periodic profile - there is a cross section at an angle to the axis of the whip, which facilitates the welding of parts.

A3 fittings are popular. With a diameter of 12 mm, the weight of 1 m of profile is 0.888 kg. The cross-sectional area is 1.131 cm.

To determine the amount of reinforcement, the length in linear meters should be calculated. But on the market the material is supplied by weight. To calculate the required volume, it should be taken into account that a length of 1 m weighs 0.888 kg. Then 1 t contains 1126 m of reinforcement (12 mm in diameter). For other diameters, you can use special tables created taking into account the weight of 1 m of rolled stock for different parts. But an error may occur due to belonging to a different class.

Calculation of the amount of reinforcement

Manufacturers supply reinforcement with a length of 11.7 m. The value is justified by the waste of the part itself when laying overlapping. The useful length in this situation is 10 m. The remaining part will go to the ligament elements with the adjacent whip. The approximate volume of blanks for a strip foundation 50 m long is 20 pieces.

Important! The arrangement of a strip foundation involves the construction of 2 tiers of reinforcement. 2 tiers correspond to 4 rods.

If you need to calculate the total number of rods for the entire perimeter of the foundation, then you should add the amount of reinforcement for connections and lintels (vertical, horizontal). For example, in a building being constructed with 4 walls, 16 m of material will be required when laying 4 rods on one wall.

The use of reinforcement when constructing a foundation

The lintels are laid out at a distance of 0.5 m. The parameters of the reinforced frame lattice depend on the size of the foundation.

A foundation with a height of 600 mm and a width of 350 mm implies a distance between the bars in the lattice equal to 500 mm and 250 mm, respectively. So, with a foundation perimeter of 50 m, 100 ring-shaped transverse connections are obtained (50:0.5=100), having a perimeter of 1.5 m (0.5*2+0.25*2).

Then the total length of the rod will be 150 m (100 * 1.5). Taking into account waste, the total volume for lintels will be 157.5 m.

After calculating the volume of reinforcement, it is necessary to estimate the amount of wire for knitting elements in the strip foundation. The consumer can choose another knitting option - with a gun or welding.

The strength characteristics of reinforcing elements make it possible to build monolithic foundations, beams, arches and other important structures. The range of products is quite wide, which ensures a high-quality selection for individual objects. Knowing the parameters of the building or structure under construction, everyone can purchase fittings that are suitable in size and properties.

ANSWER: 0 meters. (0 rods per millimeter)

The reinforcement is manufactured in accordance with GOST 5781-82 “Hot-rolled steel for the reinforcement of reinforced concrete structures. Technical conditions" and GOST R 52544-2006 "Rolled welded reinforcement of periodic profile of classes A500C and B500C for reinforcement of reinforced concrete structures. Technical specifications"

Depending on the mechanical properties, reinforcing steel is divided into classes A-I (A240), A-II (A300), A-III (A400), A-IV (A600), A-V (A800), A-VI (A1000 ). In the designation A500C and B500C, the letter A means hot-rolled or thermomechanically strengthened reinforcing bars, the letter B means cold-deformed reinforcing bars, and the letter C means weldable.

The number in the designation shows the rounded value of the yield strength in N/mm 2. The yield strength is a mechanical characteristic of a material that characterizes the stress at which strain continues to increase without increasing the load.
