The calculation formula for the theoretical weight of channel steel is: W=0.00785×waist thickness [height + e (leg width – waist thickness)].

The theoretical weight of steel bars per meter (Kg) = 0.00617 × diameter of steel bars (mm) × diameter of steel bars (mm), and the theoretical weight of steel bars (Kg) ≈ 0.00785 × cross-sectional area [Π* radius of steel bars (mm) * radius of steel bars ( mm)].

Channel steel is a carbon structural steel used in construction and machinery. It is a profiled steel material with a complex cross-section and a groove-shaped cross-section. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing.

The specifications of channel steel are mainly expressed by height (h), leg width (b), waist thickness (d) and other dimensions. The specifications of domestic channel steel range from 5-40, that is, the corresponding height is 5-40cm.

At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No. 18 to 40 are large channel steels, and No. 5 to 16 are medium channel steels. Imported channel steel is marked with actual specifications, dimensions and related standards.
