Rebar and concrete calculator
Rebar weight by diameter, length and number of bars (mass values for 1 linear m — from the GOST 34028-2016 table, for non-standard diameters — calculated by formula) and concrete volume by structure geometry.
Rebar weight
ГОСТ 34028-2016.
Concrete volume
Fill in the structure dimensions.
Data source and accuracy
The mass of 1 linear m of rebar is per GOST 34028-2016 (classes A240–A600 and others). The tabular values match the mass calculated from the nominal diameter at a steel density of 7850 kg/m³. During manufacturing, geometry deviations affecting the mass are allowed (tolerance range — in GOST 34028-2016). See also the steel products sortament.
