Angle Bar is mainly divided into two types: equilateral angle bar and unequal
angle bar. Among them, unequal angle bar can be divided into two types: unequal
width and unequal thickness.
The specifications of the angle bar are expressed by the dimensions of the side length and the side thickness. At present, the specifications of domestic angle bar are No. 2-20, and the number of centimeters of the side length is the number. The same angle bar often has 2-7 different side thicknesses. The imported angle bar indicates the actual size and thickness of the two sides and indicates the relevant standards. Generally, the angle of 12.5cm or more is a large angle bar, and the medium angle bar is between 12.5cm and 5cm. The side length bar is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering. Structures, such as house beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses, are small angle bars below 5 cm.
