Channel steel is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Channel steel can be divided into 4 types shape: cold-formed equal-side channel steel, cold-formed unequal-side channel steel,cold-formed inner-coiled channel steel, and cold-formed outer-coiled channel steel. Main features: high pressure, long support time, easy installation and not easy to deform. Main uses: Mainly used for mine tunnels, secondary support of mine tunnels, and support and support of mountain tunnels. As the main section steel for manufacturing roadway shrinkable metal supports, U-section steel is widely used at home and abroad.
