Angle steel can be composed of different stress components according to the different needs of the structure, and can also be used as the connection between components. It is widely used in all kinds of building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, and warehouse shelves, etc.

Angle steel belongs to the construction of carbon structural steel, is a simple section of steel steel, mainly used for metal components and workshop frame.Good weldability, plastic deformation and mechanical strength are required in use. The raw billet of Angle steel is low carbon square billet, and the finished Angle steel is delivered in hot rolled form, normalizing or hot rolled state.

Unequal steel angles are also right-angled; however, they have different sized axis' making them L-shaped. This section is much stronger (up to 20%) with a much higher strength to weight ratios. Their sizing is represented by side A x side B x thickness.
