This tool calculates the weight of square and rectangular box profiles by considering standard corner radii. You can choose cold-formed (EN 10219) and hot-formed (EN 10210) profiles; the hot-formed profile is slightly heavier because the corner radii are different. You can calculate for steel, stainless steel (304, 316), aluminum, copper, brass, bronze, cast iron, and other metals, and enter the density yourself for the material that is not on the list.
Formula
H, B: profile dimensions, t: wall thickness, ro and ri: radius of outer and inner corners. For t ≤ 6 mm in EN 10219 ro = 2t, ri = t; for 6 < t ≤ 10 mm ro = 2.5t, ri = 1.5t; for t > 10 mm ro = 3t, ri = 2t. In EN 10210 ro = 1.5t, ri = t.
Example
The meter weight of the 40 × 40 × 2 mm cold-formed box profile is 2.31 kg/m, and its 6 m length is 13.8 kg.
