Angle steel 
The angle steel can be composed of various stress-bearing members according to the different needs of the structure, and can also be used as the connection between the members. Widely used in various building structures and engineering structures, such as building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouses Shelves and so on.
Angle steel is a carbon structural steel for construction. It is a section steel with a simple section. It is mainly used for metal components and the frame of factory buildings. In use, it requires good weldability, plastic deformation performance and certain mechanical strength. The raw material billets for the production of angle steel are low-carbon square billets, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.

Steel Angle   It is mainly divided into two types:
equal-sided angle steel and unequal-sided angle steel. Among them, unequal-sided angle steel can be divided into unequal-sided and unequal-thickness and unequal-sided unequal-thickness.
The specifications of angle steel are expressed by the dimensions of side length and side thickness. At present, the domestic angle steel specifications are 2-20, and the number of centimeters on the side length is used as the number. The same horn steel often has 2-7 different side thicknesses. Imported angles indicate the actual size and thickness of both sides and indicate the relevant standards. Generally, those with a side length of 12.5cm or more are large angles, those with a side length between 12.5cm and 5cm are medium-sized angles, and those with a side length of 5cm or less are small angles.
The order of import and export angle steel is generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade. In addition to the specification number, the angle steel has no specific composition and performance series. The delivery length of angle steel is divided into two types: fixed-length and double-length. The range of fixed-length selection of domestic angle steel is 3-9m, 4-12m, 4-19m, 6-19m according to the different specifications. The length of angle steel made 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 steel with angular cross-section and unequal lengths on both sides. It is a kind of angle steel. Its side length ranges from 25mm×16mm to 200mm×l25mm. Rolled by a hot rolling mill.
The general specification of unequal angle steel is: ∟50*32--∟200*125, the thickness is 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 building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, Container racks and warehouses, etc.

(1) Composition index: The chemical composition of angle steel belongs to the rolled steel series for general structure, and the main verification indexes are C, Mn, P, S. According to different grades, the content varies, the approximate range is C <0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%.
(2) Inspection method: When testing the above chemical components, the commonly used standard inspection methods include GB223, JISG1211-1215, BS1837, BS Manual 19, ГОСТ22536, etc.
