Angle steel is a structural steel for construction. It is a steel section of simple section, mainly used for the frame of metal components and workshops. Good weldability, plastic deformation properties and certain mechanical strength are required in use . There are two types of unequal angle steel and unequal angle steel, among which unequal side angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness. 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 cross-section and unequal sides. It is a kind of angle steel. Its side length is from 25mm×16mm to 200mm×125mm. Rolled by hot rolling mill. The general specifications of unequal angle steel are: ∟50*32--∟200*125 with a thickness of 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.

Angle steel can be composed of various stress components according to different needs of the structure, and can also be used as a connector between 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.

Weight calculation: Weight per meter=0.00785*(side width+side width-side thickness)*side thickness
For example, 50*5 angle steel: (50+50-5)*5*0.00785=3.73 (this algorithm can only roughly calculate the weight of angle steel )
