The specifications of angle steel are expressed by the dimensions of side length and side thickness. At present, the specifications of domestic angle steel are No. 2-20, with the number of centimeters as the side length. The same angle steel often has 2-7 different side thicknesses. Imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, those with a side length of more than 12.5cm are large angle steels, those with a side length between 12.5cm and 5cm are medium-sized angle steels, and those with a side length of less than 5cm are small angle steels.
The ordering of import and export angle steel is generally based on the specifications required for use, and the steel grade is the corresponding carbon structural steel grade. Also, apart from the specification number, angle steel does not have a specific composition and performance series.
