Do you know the specifications of angle steel?

The standard of angle steel is usually expressed in terms of side length and side thickness. At present, the domestic angle steel standard is No. 2-20, with the number of centimeters of the side length being the number. The same angle steel often has 2-7 different side thicknesses. The imported angle steel indicates the actual dimensions and edge thickness on both sides and indicates 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 standards required in the application, and the steel grade is the corresponding carbon steel grade. Also, apart from the standard number, angle steel does not have a specific composition and performance series.
The delivery length of angle steel is divided into two types: fixed length and double length. The fixed length selection scale of domestic angle steel has four sizes: 3-9m, 4-12m, 4-19m, and 6-19m according to different standard numbers. The length selection range of angle steel produced in Japan is 6-15m.

The cross-sectional height of the unequal angle steel is calculated according to the long side width of the unequal angle steel. Refers to steel with an angular cross-section and unequal lengths on both sides. It is a kind of angle steel. Its side length ranges from 25mm×16mm to 200mm×125mm. Rolled by hot rolling mill. The general standard for unequal angle steel is: ∟50*32--∟200*125 with a thickness of 4-18mm

Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding industries, various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, Container racks and warehouses, etc.
