Angle steel, popularly known as angle iron, is a long strip of steel with perpendicular sides forming an angle. It can be configured into various stress-bearing members or serve as connectors between members, proving vital in building structures and engineering feats. Its applications span across building beams, bridges, power transmission towers, lifting machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar supports, and warehouse shelves.
Angle steel, a carbon structural steel for construction, boasts a simple yet effective section design. Used predominantly for metal components and structural frames in factory buildings, it necessitates good weldability, plastic deformation, and mechanical strength. Produced from low-carbon square billets, the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled states.
