1. It is expressed by the number of millimeters of side width × side width × side thickness. For example, “∠30×30×3” means an equilateral angle steel with a side width of 30 mm and a side thickness of 3 mm.

2, can also be expressed by the model, the model is the number of centimeters of the width, such as ∠ 3 #.

Introduction to angle steel: 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 model does not indicate the size of the different side thicknesses in the same model. Therefore, the side width and thickness of the angle steel are filled in the contract and other documents, so as to avoid the model number. The specification of hot rolled equal angle steel is 2#-20#.

The angle steel can be composed of various force-receiving members according to the different needs of the structure, and can also be used as a connecting member between the members. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
