Angle steel, or angle iron, is a long strip of steel with perpendicular sides forming an angle. This adaptable material serves various structural needs, forming stress-bearing members and connections. Widely employed in building structures and engineering projects, it is essential for constructing beams, bridges, power transmission towers, lifting machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installations, and warehouse shelves.
Angle steel, a type of carbon structural steel, features a straightforward section design, making it ideal for metal components and factory building frames. It demands excellent weldability, plastic deformation capabilities, and sufficient mechanical strength. Produced from low-carbon square billets, the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled states.
