Angle steel, commonly known as angle iron, is a carbon structural steel extensively used in construction. It is characterized by its long strip shape with two sides perpendicular to each other, forming a simple section profile. Angle steel is divided into two categories: equal angle steel and unequal angle steel.
The production of angle steel starts with low carbon square billets as the raw material. The finished angle steel can be in a hot-rolled, normalized, or hot-rolled state. Angle steel is versatile and can fulfill different stress requirements in structures, serving as a connection between components. It finds wide application in various building structures and engineering projects, including beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.
