DX51D GI Steel Coil Z180 Zinc Coating Galvanized Steel Coil

Factory Direct Sale Cold Rolled Zinc Coated Galvanized Steel Coils is rolled at room temperature and then rolled again below its recrystallization temperature. This process enables better control over finished product shape, thickness, dimensions, and a more consistent finish.

Cold-rolled is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Hard-rolled coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.

The current main products are covering Steel coil Cold rolled steel Metal roofing sheet steel coil,Cold Rolled series (coils/sheets), Metallic Coated series (GI,GL,galvanized, galvalumed, aluzinc, zincalume), Color Coated series (PPGI,PPGL) and their derivatives (Corrugated,Trapezoidal, Roofing sheets and Cladding),ASP ROOF.

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.

Galvanized refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and rust prevention. The main methods used are hot-dip galvanizing and electro-galvanizing. It prevents corrosion of steel, and its protective performance is closely related to the thickness of the coating.

The steel coil is a product of rolling and winding a piece of steel strip or steel sheet. The width of a steel coil is larger compared to its thickness. The method of producing steel coil is based on how it should be classified, whether as a cold-rolled, galvanized or hot rolled steel coil.

The material composition of the product is mainly iron carbon alloy, generally containing a small amount of silicon,manganese, sulfur and phosphorus. Different brands correspond to different hardness, thermoplastic, plasticity and weldability. If you don’t understand, you can tell us your requirements.

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.
