Angle steel can be composed of various stress-bearing components according to different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.

Angle steel is a carbon structural steel used in construction. It is a simple cross-section steel material. It is mainly used for metal components and factory building frames. It requires good weldability, plastic deformation performance and certain mechanical strength during use. The raw material billet for the production of angle steel is low carbon square steel billet, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.
