Generally speaking, angle steel can form various stress components according to different structural requirements, and can also be used as connectors between components. Therefore, it is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, warehouse shelves, etc.
Angle steel belongs to carbon structural steel for construction. It is a section steel with simple section. It is mainly used for metal components and plant frame. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for angle steel production is low-carbon square billet, and the finished angle steel is delivered in hot rolling forming, normalizing or hot rolling state. Angle steel, commonly known as angle iron, is a long strip of steel whose two sides are perpendicular to each other and form an angle.
Angle steel can also be divided into equilateral angle steel and unequal angle steel. The two sides of equilateral angle steel are equal in width, and the specification is based on the side width × Edge width × The edge thickness is expressed in millimeters. Such as "∟ 30" × thirty × 3 "refers to the equilateral angle steel with side width of 30mm and side thickness of 3mm. In addition, it can also be expressed by model. The model is the centimeter of side width. For example, ∟ 3# model does not represent the dimensions of different side thicknesses in the same model. Therefore, the dimensions of side width and side thickness of angle steel shall be filled in in the contract and other documents to avoid using model alone.
