Angle steel it is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: equal thickness and unequal thickness.
The specifications of angle steel are expressed by side length and side thickness. The current domestic angle steel specifications are 2-20, measured in centimeters of side length. The same horn steel often has 2-7 different edge thicknesses. The actual size and thickness of both sides of the imported angle steel are indicated, as well as the relevant standards. Generally, those with a side length of more than 12.5 cm are called large angles, those with a side length between 12.5 cm and 5 cm are called medium angles, and those with a side length of less than 5 cm are called small angles.
The ordering of import and export angle iron is generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade. Apart from the specification number, angle steel has no 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 range of domestic angle steel according to different specifications is 3-9m, 4-12m, 4-19m, 6-19m. The length of angle steel produced in Japan is 6-15m.
The cross-sectional height of the unequal angle steel is calculated based on 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 type of angle steel. Its side length ranges from 25mm×16mm to 200mm×l25mm. Rolled by hot rolling mill.
The general specifications of unequal angle steel are: ∟50*32–∟200*125, and the thickness is 4-18mm.
Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures, such as building beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, containers Waiting for shelves, warehouses, etc.
