Metal Building MaterialsIt is a general term for materials that are composed of metal elements or mainly composed of metal elements and have metal characteristics. Metal building materials include products such as threaded steel, hot-rolled steel coils, and medium and thick plates.

Hot-rolled Steel CoilIt is made from continuous casting slab or initial rolled slab as raw material. After being heated in a preliminary progressive heating furnace and descaled by high-pressure water, it enters the roughing mill. The roughing material goes through cutting head, tail, and then enters the finishing mill, where computer-controlled rolling is implemented. After final rolling, it undergoes laminar cooling (computer-controlled cooling rate) and is coiled by the coiler to become a hot-rolled coil.
