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.

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.

Dx51d Gi Metal Spangle Zinc Coated cold rolled Galvanized Steel Coil are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied.

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.

Metal Cold Rolled Galvanized Steel Coil is essentially hot rolled steel that is further processed in cold reduction materials. Here, the material is cooled followed by annealing and/or tempers rolling. Steels of different grades and specifications can be either hot or cold rolled.

Cold-rolled sheet coil has good properties, that is, cold-rolled strip and steel sheet with thinner thickness and higher precision can be obtained by cold-rolling, with high flatness, high surface finish, clean and bright surface of cold-rolled sheet, and easy to be coated. It has a wide range of processing and varieties, and has a wide range of uses.

Cold-rolled coils are a steel product produced by applying plastic deformation to hot-rolled steel on cold-rolling mills. With such processing, the product can have more accurate dimensional tolerances, better surface quality and improved mechanical properties as compared with hot-rolled coils. Cold rolling is also used to make thinner coils than hot-rolling mills can currently produce (less than 0.8-1.0 mm).

For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate.
