As we all know, generally speaking, the angle type is mainly divided into equal and unequal Angle angle two categories, which can be divided into unequal angle unequal thickness and unequal thickness two.
In addition to the type of Angle, angle specifications are usually expressed in the size of the length and thickness of the side.At present, the domestic angle steel specifications for the number of 2-20, the number of centimeters to the length of the side, the same horn steel often have 2-7 different edge thickness.The actual size and thickness of the imported angle steel on both sides are indicated and the relevant standards are indicated.General side length 12.5 cm above the large angle, 12.5 cm—5cm between the medium angle, side length 5cm below the small angle.
Import and export of angle steel orders generally use the required specifications based, its steel number for the corresponding carbon steel.It is also a series of angle steel with no specific ingredients and performance in addition to the specification number.
After understanding the type of angle, we look at the angle of the delivery length, is divided into two kinds of fixed length, double feet, the length of the range of choice of domestic angle according to the specifications of the different 3-9m, 4-12m, 4-19m, 6-19m four Range.The length of the Japanese production angle selection range of 6—15m.
The cross-section height of the unequal angle is calculated according to the long-side width of the unequal angle.Refers to the angle of the cross section and the length of the steel on both sides are not equal.Is one of the angles.Its side length from 25mm × 16mm ~ 200mm×l25mm.By the hot rolling mill.General specifications for the equilateral angle:∟50 50 * 32 -- ∟200 * 125 thickness of 4-18mm
There are many types of Angle, angle is widely used in a variety of metal structures, bridges, machinery manufacturing and shipbuilding, a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
