Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other on both sides. There are equal angle steel and unequal angle steel. The sides of the equiangular steel are equal in width. The specifications are expressed in millimeters of side width × side width × side thickness.steel angle for sale For example, “∠30×30×3” means an equilateral angle steel with a side width of 30 mm and a side thickness of 3 mm. It can also be expressed by model number, the model number is the number of centimeters of the side width, such as ∠3#. Model does not indicate the size of different sides in the same model.

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 width and unequal thickness.

The specifications of the angle steel are expressed by the dimensions of the side length and the side thickness. At present, the specifications of domestic angle steel are 2-20, and the number of centimeters of the side length 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 the two sides and indicates the relevant standards. Generally, a large angle steel having a side length of 12.5 cm or more is a medium angle steel between 12.5 cm and 5 cm, and a small angle steel having a side length of 5 cm or less.

The order of import and export angle steel is generally based on the specifications required in use, and the steel number is the corresponding carbon steel number. In addition to the specification number, angle steel has no specific composition and performance series.

The delivery length of angle steel is divided into two types: fixed length and double rule. The range of fixed length of domestic angle steel has four ranges of 3-9m, 4-12m, 4-19m and 6-19m depending on the specification number. The length of the Japanese angle steel is selected from 6 to 15 m.

The height of the section of the unequal angle steel is calculated as the width of the long side of the unequal angle steel. Refers to steel with an angled section and unequal lengths on both sides. It is one of the angles. Its side length is from 25mm x 16mm to 200mm x l25mm. It is rolled by a hot rolling mill. The general unequal angle steel specifications are: ∟50*32–∟200*125 thickness is 4-18mm.steel square bar

Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding industries, various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, Container racks, warehouses, etc.

Angle steel per meter weight = 0.00785 * (side width + side width – side thickness) * side thickness

For example, 50*5 angle steel: (50+50-5)*5*0.00785=3.73 (this algorithm can only roughly calculate the weight of the angle steel, the actual hardware manual shall prevail!)
