Descriptions
Product Introduction
A channel steel is a long steel bar with a concave groove-shaped cross-section, a type of shaped steel. It is usually produced by hot rolling or cold rolling. During production, specific rolling mill equipment gradually rolls the steel billet into a channel steel with specific specifications and shapes. Its cross-section consists of a web and two flanges, resembling a concave groove. This unique cross-sectional design gives channel steel special mechanical properties and wide application value. There are many specifications of channel steel; its dimensions are usually expressed in millimeters as height (h) × leg width (b) × web thickness (d), such as "[100×48×5.3]" which indicates a channel steel with a height of 100 mm, leg width of 48 mm, and web thickness of 5.3 mm. Users can choose the appropriate specifications according to different engineering needs.
