Application:

Angle steel is mainly used to make frame structures, such as towers for high-voltage power transmission, frames on both sides of the main girder of steel structure bridges, columns and booms of tower cranes on construction sites, columns and beams in workshops, etc. Small places such as festivals A shelf in the shape of a flowerpot is placed on the roadside, a shelf with an air conditioner and solar energy is hung under the window, etc.
The manufacturing process of angle steel is relatively simple. Generally, large steel companies do not produce this thing. The production process can be divided into two types: hot rolling and cold bending. Hot rolling is used for large-sized angle steel, and cold bending is generally relatively small. The standard process is to use a steel billet (such as a square billet) to be gradually rolled into a ∨ shape through a dedicated section steel rolling mill for multiple passes. It is formed by direct rolling (bending) of sheet or strip steel. There is no transition arc on the inner side of the corner, and because it is formed by bending, the internal stress at the corner is large, and the mechanical properties are poor. The most important point is that the material is not guaranteed. It may even be “ground bar steel”. Such angle steel cannot be bent or welded. At most, long and short holes can be drilled.
