Wholesale Steel Coil Price Cold Rolled Galvanized steel coil

Galvanised steel is represented by cold- and hot-rolled coils with a zinc coating, which helps to protect the steel against atmospheric corrosion. Galvanised steel coils are successfully used in industries with stringent requirements for corrosion resistance, durability, strength and appearance, and can be formed or have various coatings applied.

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

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.

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.

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, 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

Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate.

Top quality JIS 0.45mm*1200mm galvanized steel coil can produce zero spangles, small spangles, ordinary spangles, etc. The thickness is from 0.125mm to 4.5mm, the width is from 500mm to 1250mm, the zinc coating is from 40-275 g/m², the surface is passivated and oil can be coated.

Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. The construction industry is mainly used to manufacture anti-corrosion roof panels and roof grilles of industrial and civil buildings

Galvanized Steel Sheet in 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.
