Angle steel, also known as angle iron, is the two sides of the vertical into 90 degrees right angle of the steel bar, divided into equilateral angle steel and unequal angle steel; Angle steel is a simple cross-section section steel steel used in the construction of the building is a carbon structural steel; mainly used for metal components and plant frames, etc., so that the angle steel is required to have a better weldability, plastic deformability and to withstand a certain degree of mechanical strength.
The main raw material of angle steel is low carbon square steel billet, which is supplied in finished products in hot rolled forming, normalized or hot rolled condition; it is widely used in building and engineering structures, such as beams, bridges, electric towers, reaction towers, container racks, cranes, transportation machinery, ships, industrial furnaces and warehouse steel structures.
