Channel steel is used in building structures and vehicle manufacturing, and is divided into hot-rolled channel steel and curved channel steel. Hot-rolled channel steel is divided into two types: ordinary type and light type. The channel steel specifications currently produced range from No. 5 to No. 40, and the corresponding height is 5 cm to 40 cm. At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. Channel steel is widely used in vehicle manufacturing and various metal structures. Channel steel is a carbon structural steel for construction and machinery. It is a section steel with complex sections, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, the channel steel is required to have good welding, riveting performance and comprehensive mechanical properties.
