The specification of unequal angle steel is expressed by the dimensions of side length and side thickness. Refers to steel with angular cross-section and unequal lengths on both sides. It is a kind of angle steel. Its side length ranges from 25mm×16mm to 200mm×125mm. Rolled by a hot rolling mill. Hot-rolled unequal angle bar is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding industries.
Hot-rolled unequal angle bar is a hot-rolled long steel strip with two sides perpendicular to each other in an angle and with different widths. The angle steel can be composed of various stress-bearing members according to the different needs of the structure, and can also be used as the connection between the members.
