Steel reinforcement is produced by hot rolling in accordance with GOST 5781-82 and is widely used in construction. Designed to strengthen concrete foundations.
Used to build bridges, buildings, skyscrapers, highways, and runways. The most difficult and labor-intensive work in the production of reinforced concrete structures is the construction of a reinforcing mesh.
With the help of such a mesh, the strength of the structure increases significantly. This method is the most economical, because the price of steel reinforcement is not high.
I distinguish 6 classes of types of fittings A1, A2, A3, A4, A5, A6.
A1 - designates steel reinforcement with a smooth surface. Manufactured according to GOST 5871 from steel grades: St3ps, ST3sp, St3kp. Its diameter, weight and cross-sectional area are shown in the table below.
A2 - designates reinforcement with spiral protrusions. Manufactured according to GOST 5871 from steel grades: St5ps, ST5sp, St18G2S. The diameter of such fittings varies from 10 to 80 mm.
A3 - fittings with a protruding herringbone pattern. Manufactured according to GOST 5871 from steel grades: 35GS, 25G2S, 32G2Rps. This class of reinforcement is most often found in construction
A4,5,6 - reinforcement with the same pattern as A3, only the distance between the ribs is greater. This type of steel reinforcement is rarer. Manufactured according to GOST 5871 from steel grades: A4 (80С, 20ХГ2Ц); A5(23Х2Г2Т); A6(22Х2Г2АУ, 22Х2Г2Р, 20Х2Г2СР). The diameter of A4 and A5 is from 10 to 32 mm, and that of A6 is from 10 to 22 mm.

Reinforcement rod weight 12 mm
For a long time I gathered my courage to start building my own country house. To carry out the work of pouring the foundation, it was necessary to use a large amount of reinforcing bar with a diameter of 12 millimeters. I immediately had a question about how much 12 mm reinforcement weighs, but I will write about this below.
Reinforcement and concrete #8212; inseparable
Getting acquainted with various country house construction projects on the Internet, I saw that a large number of house elements are made of monolithic concrete. It is these structures that require the expenditure of materials for reinforcement.
The weight of the reinforcing bars required for reinforcing the structure is calculated by multiplying the total length of the entire reinforcing bars by the weight of one linear meter of reinforcement.
The weight of one linear meter of reinforcing bars is a constant unit. The weight of a linear meter of reinforcing bars depends on the composition of the steel used in the manufacture of the reinforcement, as well as on its cross-section.
Knowing the mass of the reinforcing bars, you can estimate the degree of reinforcement of the structure, which depends on the ratio of the mass of the reinforcing bars to the volume of concrete used when pouring the structure. By the way, you can simply use an online calculator for the foundation.
Important! The degree of reinforcement allows you to calculate the cost of the structure.
How much does the fittings weigh?
The weight of a meter of reinforcing bars with the same steel alloy composition completely depends on the diameter of the reinforcing bars and the cross-section of the reinforcing bars.
With a diameter of reinforcing bars equal to three millimeters and a cross-sectional area equal to 0.071 square centimeters, the specific weight of such reinforcement is 0.055 kilograms per linear meter.
With an increase in diameter by one millimeter, the cross-sectional area is 0.126 square centimeters, and the weight of one meter of such reinforcement is approximately 0.098 kilograms per meter.
With a diameter of a metal reinforcement bar of five millimeters, the cross-sectional area increases to a value equal to 0.196 square centimeters, while the weight increases to a value equal to 0.154 kilograms per meter.
When using reinforcement with a diameter of six millimeters, the cross-sectional area is 0.385 square centimeters, while the mass of one meter is 0.222 kilograms per meter. In principle, this can be found out from the reinforcement weight table.

Assortment of fittings A1
According to regulatory documentation, products are produced in the diameter range of 6-40 mm. It goes on sale in coils - up to 10 mm in diameter - or rods 6-12 mm long. The weight of products can be determined by the formula M = ρ* l*(π*d2)/4 , in which:
M – product mass, kg;
ρ – average steel density, taken equal to 7850 kg/m3;
π – 3.14;
d – cross-sectional diameter, m;
l – length, m.
Another option for calculating the mass of a batch of reinforcement is using a table from which the mass of 1 m is determined, and then this value is multiplied by the total footage of the batch.

Weight of 1 m2 of tiles, stones, mosaics
Such an indicator as the weight of the facing material is a very important parameter that determines the scope of application of the facing material. Next, let's take a closer look at what you should pay attention to.
Weight of facing materials
The weight of the facing material determines the requirements for the surface to be covered and for the adhesives used!
You can formulate a gradation of application as follows:
- For finishing the interior walls, the lightest and thinnest tiles will be used, the weight of which will not exceed 16 kg per 1 m2.
- More durable and thick tiles will be used as flooring; in this case, the weight can reach 25 kg per 1 m2.
- They try to select the facing material for facades in the range of 15-20 kg per 1 m2.
- Since the materials used to cover sidewalks must have sufficient strength, the weight of paving products can be about 100 kg per 1 m2.
The weight of facing materials can be influenced by various factors, such as: material density, dimensions, water absorption coefficient, porosity, etc.
Most often, the criterion of the weight of the facing material is taken into account to determine the required quantity and properties of the adhesive composition, as well as when planning transportation. For calculation, different weight criteria are used, such as: specific gravity, volumetric weight and weight of one unit.
At the moment, the following types of facing materials are most often used in construction and renovation:
- Ceramic tiles or tiles
- Clinker
- Porcelain tiles
- Mosaic
- Paving slabs
- Stone
- Fake diamond

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.
