Flat Bar / Patti Weight Calculator
MS flat (patti) weight from width × thickness — fabrication estimating staple.
50×6 flat = 2.36 kg/m — the gate-and-grille fabricator's bread and butter. Multiply mm² of cross-section by 0.00785 for any solid steel shape.
Formula
Flat Bar / Patti Weight Calculator is a free flat bar 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 Flat Bar / Patti Weight Calculator
