GOST 5781-82 regulates the production of hot-rolled steel reinforcement used in reinforced concrete structures. This standard ensures the strength, flexibility, and durability of materials, which are critical for building safety.

The table of weight of reinforcement according to GOST 5781-82 helps to accurately calculate the load on the structure and avoid errors in design.

Hot-rolled steel: key advantages

Reinforcement made of hot-rolled steel according to GOST 5781-82 is characterized by high adhesion to concrete, resistance to corrosion, and temperature fluctuations. Its weight per 1 meter depends on the diameter: for example, a 12 mm bar weighs 0.888 kg/m, while a 20 mm bar weighs 2.47 kg/m.

These parameters are specified in the table of weight of reinforcement, which simplifies the selection of materials for foundations, slabs, and columns.

How to use the table of weight of reinforcement GOST 5781-82

The table of weight of reinforcement per meter contains data for all sizes - from 6 to 80 mm. For calculations, it is necessary to:

Determine the diameter of the bar;
Find the corresponding value in the GOST 5781-82 table;
Multiply the weight per 1 meter by the total length of the bars.

This eliminates the risk of steel overconsumption and ensures estimate accuracy.

Applications of reinforcement according to GOST 5781-82

Hot-rolled reinforcement is used in monolithic reinforced concrete structures, road pavements, bridges, and industrial facilities. Compliance with GOST 5781-82 confirms that the steel has passed tension and bending tests, and its weight meets the declared standards.
