SGCC Dx51d Cold Rolled Steel Coil Galvanized Steel Coil

The cold plate is a hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no scale is produced, therefore, the cold plate has good surface quality and high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled steel sheets, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel

Cold Rolled Galvanized Steel Strip Coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery and commerce industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.

Cold rolled steel is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.

Galvanized Steel coil is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.

Cold-rolled steel coils are made of hot-rolled coils and rolled at room temperature below the recrystallization temperature. Cold-rolled steel has good performance. That is, cold-rolled steel can be thinner and more precise.

Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required. Until now, cold rolled coils have been available and successfully used for a variety of applications.

Compared with hot rolled steel plate, Galvanized steel Ss400 cold rolled steel coil thickness is more accurate, and the surface is smooth, beautiful, but also has a variety of superior mechanical properties, especially machining performance.

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

Cold rolled coil could supply better control of thickness, shape, width, surface finish, and other special quality features that compliment the emerging need for highly engineered end uses. Take construction projets for example: steel sheds, industrial buildings, and garages.
