It is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness.
It is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness.
The specifications of angle steel are expressed by the dimensions of side length and side thickness. At present, the specifications of domestic angle steel are No. 2-20, with the number of centimeters as the side length. The same angle steel often has 2-7 different side thicknesses. Imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, those with a side length of more than 12.5cm are large angle steels, those with a side length between 12.5cm and 5cm are medium-sized angle steels, and those with a side length of less than 5cm are small angle steels.
The ordering of import and export angle steel is generally based on the specifications required for use, and the steel grade is the corresponding carbon structural steel grade. Also, apart from the specification number, angle steel does not have a specific composition and performance series. The delivery length of angle steel is divided into two types: fixed length and double length. The fixed length selection range of domestic angle steel has four ranges: 3-9m, 4-12m, 4-19m, and 6-19m according to different specifications. The length selection range of angle steel produced in Japan is 6-15m.
The cross-sectional 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 lengths on both sides. It is a kind of angle steel. Its side length ranges from 25mm×16mm to 200mm×125mm. Rolled by hot rolling mill. General unequal angle steel specifications 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 industries, various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, Container racks and warehouses, etc.

Cold rolled steel processing methods
Cold rolled steel is steel produced by cold rolling. Cold rolling is to further thin the No. 1 steel plate to a target thickness under room temperature conditions. Compared with hot-rolled steel plates, cold-rolled steel plates have a more precise thickness, smooth and beautiful surface, and have various superior mechanical properties, especially in terms of processing performance.

Corrugated board, also called profiled board, is made of color-coated steel sheets, galvanized sheets and other metal sheets that are rolled and cold-bent into various corrugated profiled boards. It is suitable for industrial and civil buildings, warehouses, special buildings, and large-span buildings. Roofs, walls and interior and exterior wall decoration of steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fireproof, rainproof, long life, maintenance-free, etc., and has been widely promoted and used.
