Angle Steel

Channel steel is commonly known as angle iron and is a long strip of steel with two sides that are perpendicular to each other and form an angle. There are equal-sided channel steel and unequal-sided channel steel. The two sides of equal-sided channel steel have equal widths. Its specifications are expressed in millimeters as width × width × thickness. For example, "∠30×30×3" means an equal-sided channel steel with a width of 30 millimeters and a thickness of 3 millimeters. It can also be represented by a model, where the model is the centimeter value of the width. For example, ∠3#. The model does not represent the dimensions of different thicknesses within the same model. Therefore, when filling in the width and thickness of the channel steel on contracts and other documents, it is necessary to provide complete information to avoid using the model alone. The specifications of hot-rolled equal-sided channel steel range from 2# to 20#. Channel steel can be combined to form various different load-bearing components according to different structural needs, and can also be used as connection pieces between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container frames, and warehouse shelves, etc.
