Different types of angle steel
2022-05-05
Angle steel is a long strip of steel whose two sides are perpendicular to each other. It is mainly divided into two types: equal-sided angle steel and unequal-sided angle steel.
The specification of angle steel is expressed by the dimensions of side length and side thickness. At present, China's angle steel specifications are 2-20, and the number of centimeters of the side length is the number. The same angle steel often has 2-7 different side of thicknesses. Imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, the large angle steel with a side length of 12.5cm or more is a large angle steel, the medium angle steel with a side length of 12.5cm-5cm, and a small angle steel with a side length of less than 5cm. The order of import and export angle steel is generally based on the specifications required in use, and its steel grade is the corresponding carbon steel grade. The delivery length of angle steel is divided into fixed length and double length. The selection range of fixed length of domestic angle steel is 3-9m, 4-12m, 4-19m, 6-19m according to the different specifications. The length of angle steel produced in Japan ranges from 6 to 15m.
Unequal angle steel refers to the steel with an angular section and unequal lengths on both sides. It is a kind of angle steel and is rolled by a hot rolling mill. Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses, etc.
