What is Angle Steel?

Angle Steel, commonly known as angle steel, is a long strip of steel that is perpendicular to each other on both sides

Angle steel is divided into equal angle steel and unequal angle steel. Angle steel can be composed of various different stressed components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in 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 warehouse shelves. In the field of agricultural machinery, angle steel is mainly used as the skeleton or connector of various machinery and devices, and the common connection methods for other components fixed on the angle steel are welding and bolts.

The two sides of the equilateral angle steel are equal in width, and its specifications are expressed in millimeters of side width× side width × side thickness, such as "∠30×30×3". It can also be expressed by the model number, which is the number of centimeters of the side width, such as ∠3#. The model does not represent the size of different side thicknesses in the same model, so the side width and side thickness of the angle steel should be filled in on the contract and other documents to avoid being represented by the model alone. The specifications of hot-rolled equilateral angle steel are 2#-20#.

Angle Iron is a long strip of steel that is angularized to each other on both sides. There are equal angle steel and unequal angle steel. The two sides of an equilateral angle are equal in width. Its specifications are expressed in millimeters of side width× side width × edge thickness. For example, "∟30×30×3", which means that the side width is 30 mm and the side thickness is 3 mm. It can also be expressed by the model number, which is the number of centimeters of the side width, such as ∟3#. The model does not represent the size of different side thicknesses in the same model, so the side width and side thickness of the angle steel should be filled in on the contract and other documents to avoid being represented by the model alone. The specifications of hot-rolled equilateral angle steel are 2#-20#. Angle steel can be composed of various different stressed components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in 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.

It is mainly divided into two categories: equilateral angle steel and unequal angle steel, of which unequal angle steel can be divided into two types: unequal equal thickness and unequal equal thickness.

The size of the angle steel is expressed by the dimensions of the side length and the edge thickness. At present, the specifications of domestic angle steel are 2-20, and the number of centimeters of side length is the number, and the same angle steel often has 2-7 different side thicknesses. The imported angle steel is marked with the actual size and edge thickness on both sides and the relevant standards are indicated. Generally, the side length of more than 12.5cm is a large angle steel, the one between 12.5cm and 5cm is a medium-sized angle steel, and the side length is less than 5cm is a small angle steel.

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 junction steel number. It is also an angle steel that does not have a specific composition and performance series except for the specification number. The delivery length of angle steel is divided into two kinds of fixed length and double ruler, and the selection range of domestic angle steel is 3-9m, 4-12m, 4-19m and 6-19m according to the different specifications. The length of angle steel made in Japan is selected from 6 to 15 m.

The cross-sectional height of the unequal angle is calculated according to the length and width of the unequal angle. Refers to steel with an angular cross-section and unequal lengths on both sides. It is one of the angle steels. Its side length is from 25mm×16mm~200mm×l25mm. It is rolled by a hot rolling mill. The 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.
