Angle steel can be formed according to the different needs of the structure of a variety of different stress members, but also can be used as the connection between members.Widely used in various building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench support, power distribution pipes, bus support installation, and warehouse shelves. Angle steel is a kind of carbon structural steel used in construction. It is a simple section of steel. It is mainly used for metal components and the frame of workshops.Good weldability, plastic deformation and mechanical strength are required in use.The raw steel billets for Angle steel production are low carbon square billets, and the finished Angle steel is delivered in hot rolled forming, normalizing or hot rolled state.
