What are the characteristics of Angle steel

Angle steel: commonly known as Angle iron, it is a long steel bar with vertical angles on both sides. There are equal angles and unequal angles. The two sides of 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", that is, the side width of 30 mm, the side thickness of 3 mm equal Angle steel. It can also be represented by the model, which is the number of centimeters of the width of the side, such as ∠3#. The model does not indicate the dimensions of different side thicknesses in the same model, so the side width and side thickness dimensions of the Angle steel are complete in the contract and other documents, so as to avoid being represented by the model alone. Hot rolled equal-edge Angle steel specifications are 2#-20#. Angle steel can be composed of different stress components according to the different needs of the structure, and can also be used as a connection between the components. It is widely used in various building structures and engineering structures, such as beams, Bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
