Q345 angle steel bar 

Angle steel bar, commonly known as angle iron, is a long strip of steel whose two sides are perpendicular to each other and form an angle.

Angle steel bar is widely used in all kinds of building structures and engineering structures, such as beams, Bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks, cable ditch support, power piping, bus support installation, and warehouse shelves, etc.

Type of angle steel bar

Angle steel bar is mainly divided into equilateral angle steel and unequal angle steel. Unequal angle steel can be divided into unequal edge equal thickness and unequal edge unequal thickness.

The specification of angle steel is expressed by the dimension of side length and side thickness. At present, the specification of domestic angle steel is 2-20, with the number of centimeters of side length as the number. The same angle steel often has 2-7 different side thicknesses. The actual size and thickness of both sides of the imported angle steel shall be indicated, and relevant standards shall be indicated. Generally, the large angle steel with a side length of more than 12.5cm, the medium angle steel with a side length of 12.5cm-5cm, and the small angle steel with a side length of less than 5cm.

The section height of unequal angle steel is calculated according to the length and width of unequal angle steel. It refers to steel with angular section and unequal length on both sides. It is one of the angle steel. Its side length is 25mm × 16mm～200mm × l25mm。 It is rolled by hot rolling mill.

Angle steel bar USE

Angle steel bars are used to offer a strengthened support to structures that otherwise would not be able to endure the pressure placed on them. They are also used to reinforce edges on surfaces to prevent damage or erosion due to weathering. In the simplest sense, angle bars are used to protect any edges and corners that are required to hold their shape.
