Zhengde Brief introduction of angle steel: 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.
Types of angle steel: mainly divided into two types: equilateral angle steel and unequal side 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 delivery length of Angle steel is divided into two kinds of fixed size and double size, and the selection range of domestic Angle steel is 3-9m, 4-12m, 4-19m, and 6-19m according to the different specifications. The length selection range of Angle steel produced in Japan is 6-15m.
The section height of the unequal Angle steel is calculated according to the long side width of the unequal Angle steel. Refers to the section is angular and the length of the two sides are not equal steel. It is a kind of Angle steel. Its side length is 25mm×16mm ~ 200mm×l25mm. It is rolled by hot rolling mill. The general specification of unequal Angle steel is; Angle 50*32-- Angle 200*125 has a thickness of 4-18mm
