Steel angles are one of the most versatile steel products. They are commonly used for structural support in the form of trusses, reinforcing, brackets, support beams and braces. Some construction projects include bridges, warehouses, residential housing, and commercial buildings. Structural steel angles are also used in everyday steel projects like equipment, frames, furniture, shelving (slotted angle) and more.

Steel angle is divided into equal steel angle and unequal steel angle. The raw billet for the production of steel angles is low carbon square billet, and the finished steel angle is devided into hot rolled, normalized or hot rolled state. Steel angle can make up different stress components according to the different needs of the structure, as the connection between components.
