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.

Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by “pickling” it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll.

Galvalume Coil composition by weight ratio of 55% aluminum,43.4% zinc,1.6% silicon, at high temperature 600 high temperature solidification and aluminized zinc plate surface is a unique smooth flat gorgeous star flower, the base color is silver white special coating structure makes it has excellent corrosion resistance

Cold-rolled coil refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole coil with a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will generate more internal stress and are often annealed after cold-rolling.

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.

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.

We are the professional galvanized steel products supplier in China. The company focus on galvanized production for 7 years, we have our own production line, supply galvanized coil, galvanized sheet, galvanized pipe and coating products. Our company has 200 people and a monthly output of 6,000 tons.

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.
