Angle steel

Angle steel

　　Angle steel can form various stress components according to different structural needs, and can also be used as connectors between components. 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 is a 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.

　　Appearance quality

　　The surface quality of angle steel is specified in the standard. Generally, there shall be no harmful defects in use, such as delamination, scar, crack, etc.

　　The allowable range of geometric deviation of angle steel is also specified in the standard, generally including bending, edge width, edge thickness, top angle, theoretical weight, etc., and it is specified that the angle steel shall not have significant torsion.
