We all know that, generally speaking, the types of angle steel are mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal edge thickness and unequal edge thickness.
In addition to the type of angle steel, the specifications of angle steel are usually expressed by the dimensions of side length and side thickness. At present, the specifications of domestic angle steel are 2-20, and the number of centimeters of sides is the number. The same angle steel often has 2-7 different side thicknesses. The imported angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, those with a side length of 12.5cm or more are large angle steels, those between 12.5cm and 5cm are medium-sized angle steels, and those with sides less than 5cm are small angle steel.
The ordering of import and export angle steel is generally based on the specifications required in use, and its steel number is the corresponding carbon steel grade. It is also that angle steel has no specific composition and performance series except for the specification number.
After understanding the type of angle steel, let's take a look at the delivery length of the angle steel, which is divided into two types: fixed length and double length. , 6-19m four ranges. The length of the angle steel produced in Japan is 6-15m.
的 The cross-section height of the unequal-angle angle steel is calculated according to the long side width of the unequal-angle angle steel. Refers to steel with an angular cross section and unequal length on both sides. It is one of the angle steels. Its side length is from 25mm × 16mm to 200mm × l25mm. Rolled by a hot rolling mill. The general specifications of the unequal angle steel are: ∟50 * 32--∟200 * 125 and the thickness is 4-18mm.
There are many types of angle steel. Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, 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.
