The usage of steel channel
Steel channel is built from and mechanical carbon structural steel, is a kind of complex profile steel steel, its cross section for the groove shape. Steel channel is mainly used in curtain wall engineering, building structure, mechanical equipment and vehicle manufacturing.
A channel is a strip of steel with a concave section.The specification is expressed in millimeters of waist height (h)* leg width (b)* waist thickness (d). For example, 120*53*5 means steel channel with waist height of 120 mm, leg width of 53 mm, steel channel with waist thickness of 5 mm, or 12# steel channel .For steel channel with the same waist height, if there are several different leg width and waist thickness, add a, b and c to the right side of the model to distinguish them, such as 25a# 25b# 25c#, etc.
