The angle steel can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connection between the components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouses Shelves etc.
Angle steel is a carbon structural steel for construction. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for producing angle steel is low carbon square billet, and the finished angle steel is delivered in hot-rolled, normalized or hot-rolled state.
It is mainly divided into two types: equal-sided angle steel and unequal-sided angle steel. Among them, unequal-sided angle steel can be divided into two types: unequal-sided and equal-thickness and unequal-sided and unequal-thickness.
The specification of angle steel is expressed by the dimensions of side length and side thickness. At present, the domestic 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 thicknesses. Imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, large angle steels with a side length of 12.5cm or more are medium-sized angle steels with a side length of 12.5cm-5cm, and small-sized angle steels with a side length of less than 5cm.
Vector diagram of equilateral angle steel The order of import and export angle steel is generally based on the specifications required in use, and its steel number is the corresponding carbon steel steel number. In addition to the specification number, angle steel has no specific composition and performance series. 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.
The section 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 section and unequal lengths on both sides. It is a kind of angle steel. Its side length is 25mm×16mm～200mm×125mm. Rolled by hot rolling mill.
The general unequal angle steel specifications 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 beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, Container racks and warehouses, etc.
