Stainless steel square bar
[square steel bar] rolled or processed into a square section
Stainless steel square bar
Calculation of theoretical steel weight
The unit of measurement for calculating the theoretical weight of steel is kilogram (kg). The basic formula is:
W(weight, kg)=F(cross-sectional area mm2)×L(length, m)×ρ(density, g/cm3)×1/1000
Product Application:
Stainless steel square bar is mainly used for fine decoration, such as doors and windows.
Cold drawn bright square steel sizes : 3×3mm-80×80mm
