Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#. The specifications of hot-rolled modified channel steel supplied by agreement between the supplier and the buyer are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panels. Channel steel is often used in conjunction with I-beams.
Channel steel can be divided into 4 types according to shape: cold-formed equal-edge channel steel, cold-formed unequal-edge channel steel, cold-formed inner curled channel steel, and cold-formed outer curled channel steel.
According to the theory of steel structure, the channel steel wing plate should bear the force, which means that the channel steel should be standing up instead of lying down. Angle steel can be used to form various stress-bearing components according to different structures, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, and lifting and transportation machinery. , ships, industrial furnaces, reaction towers, container racks, cable trench brackets, power piping, busbar bracket installation, and warehouse shelves, etc. Angle steel is carbon structural steel for construction. It is a simple cross-section steel material, mainly used for metal components and factory buildings. framework etc. It requires good weldability, plastic deformation performance and certain mechanical strength during use. The raw material billet for angle steel production is low carbon square steel billet, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.
