In construction, accurate calculation of the weight of steel reinforcement is critically important for designing structures. Weight tables approved by GOST and TU are used for this purpose.
GOST 5781-82: classic reinforcement for reinforced concrete structures
The standard GOST 5781-82 regulates the production of hot-rolled reinforcement of classes A1-A6. The weight table of reinforcement according to this GOST includes diameters from 6 to 80 mm. For example, the weight of 1 meter of 12 mm diameter reinforcement is 0.888 kg, and for 20 mm it is already 2.47 kg. This data is indispensable for calculating loads and material costs.
GOST 34028-2016 and GOST R 52544-2006: modern standards
The standard GOST 34028-2016 (analogous to ISO 6935-2) is used for high-strength reinforcement used in bridges and high-rise buildings. GOST R 52544-2006 establishes requirements for weldable reinforcement. The weight table of reinforcement according to these standards takes into account not only the diameter, but also the ribbing, which affects the mass per meter.
Weight Table for 1 Meter of Steel Reinforcement: Practical Application
For quick calculations, use the weight table of steel reinforcement. Example data for diameters 6-32 mm (according to GOST 5781-82):
- 6 mm - 0.222 kg/m;
- 12 mm - 0.888 kg/m;
- 16 mm - 1.58 kg/m;
- 20 mm - 2.47 kg/m;
- 32 mm - 6.31 kg/m.
Clarify the parameters in TU 14-1-5526-2006 for thermally strengthened bars and in TU 14-1-5254-2006 for reinforcement with anti-corrosion coating.
How to Choose the Right Weight Table?
When working with tables, pay attention to the standard specified in the project. For example, the weight of steel reinforcement table per meter according to GOST 5781-82 may differ from the data according to GOST 34028-2016 due to differences in production technology. Always check the relevance of regulations - this guarantees the accuracy of calculations and the safety of structures.
