Channel steel is a long strip of steel with a groove-shaped cross-section. Channel steel belongs to the carbon structural steel for construction and mechanical use is a complex cross-section of section steel, its cross-section shape is groove-shaped. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use requires it to have good welding, riveting performance and comprehensive mechanical properties. The raw material billet for the production of channel steel is carbon steel with carbon content not exceeding 0.25%.
0.25% carbon steel or low alloy steel billet. Finished channel steel by hot forming, normalizing or hot rolling state delivery. Its specifications to waist height (h) * leg width (b) * waist thickness (d) of the number of millimeters, such as 100 * 48 * 5.3, said the waist height of 100 millimeters, the leg width of 48 millimeters, the waist thickness of 5.3 millimeters of the channel steel, or 10 # channel steel. Waist height of the same channel steel, such as several different leg width and waist thickness also need to be added abc to the right of the model number.
The right side of the model number plus abc to be distinguished, such as 25#a25#b25#c and so on.
