RHS / SHS Tube Weight Calculator
Rectangular & square hollow section weight with corner-radius correction.
100×50×3 RHS ≈ 6.7 kg/m. Catalogue values run ~1.5% below the sharp-corner math because of rounded corners — the correction is built in here.
Formula
RHS / SHS Tube Weight Calculator is a free rhs weight for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About RHS / SHS Tube Weight Calculator
Rectangular & square hollow section weight with corner-radius correction. The calculation implements A ≈ 2t(H+W) − 4t²; ×0.985 corner-radius correction; W = A×7850 (IS 4923 / EN 10219 section tables). 100×50×3 RHS ≈ 6.7 kg/m. Catalogue values run ~1.5% below the sharp-corner math because of rounded corners — the correction is built in here.
