Channel steel is a long strip of steel with a groove-shaped cross-section.

Channel steel is a long strip of steel with a groove-shaped cross-section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.China's channel steel imports are greater than its exports. The main producing areas are Tangshan Iron and Steel, Baotou Iron and Steel, Shanshan Iron and Steel, Huangte, Maanshan Iron and Steel, Xuanyuan Iron and Steel, Nippon Steel and other steel mills.

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot-rolled ordinary channel steel is 5-40#. The specification of hot-rolled flexible channel steel supplied by agreement between the supplier and the buyer is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. Channel steel is often used in conjunction with I-beam steel.Channel steel can be divided into 4 types according to shape: cold-formed equilateral channel steel, cold-formed unequal-sided channel steel, cold-formed inner-curled channel steel, and cold-formed outer-curved channel steel.According to the theory of steel structure, the channel steel wing plate should be stressed, that is to say, the channel steel should be standing, not lying down.
