The weight of the flat bar is calculated by width × thickness × density. 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
Meter weight (kg/m) = Width (mm) × Thickness (mm) × Density ÷ 1000
Example
The meter weight of the 50 × 5 mm steel flat bar is 1.96 kg/m.
