Cold rolled steel coil SPCD

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 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.

Galvanized Steel Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.

Factory Cold Rolled Steel Coil Full Hard galvanized Steel Coil immersing the thin steel plate in the molten zinc bath, and adhering a layer of zinc thin steel plate on the surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the zinc-melted plating tank to make galvanized steel plate; alloyed galvanized steel plate.

Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides.Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 30 – 275 grams per squaremeter

Cold Rolled Steel Coil have good properties, and cold-rolled strips and steel sheets with thinner thickness and higher precision can be obtained by cold-rolling.

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.

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 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.

Ral7016 Dx51d PPGI Gi cold rolled Steel Coil is produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.The zinc layer provides excellent corrosion resistance so that it can prolong the service life of the product.

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.
