DC04 galvanized sheet metal coil Cold Rolled steel coil

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. This kind of steel plate is also made by the hot-dip method, but it is heated to about 500 °C immediately after exiting the tank to form an alloy film of zinc and iron. This galvanized steel coil has good paint adhesion and weldability.

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 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.

Galvanized strip steel is a cold-rolled or hot-rolled, long and narrow strip of steel that is plated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

GI galvanized steel coil z275 zinc sheet metal 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.

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 steel coil is a kind of steel coil that immersed in the dissolved zinc bath to adhere to the surface with a layer of zinc. At present, the main method is to make galvanized steel coil be dipped in a bath with dissolved zinc.

Coils are divided into chilled coils and cold rolled coils. The difference between the two is that in appearance, the general chilled coil is slightly black; the surface quality, structure, and dimensional accuracy of the cold-rolled sheet are better than that of the chilled coil; in terms of performance, because the hot-rolled coil goes through the cold rolling process The directly obtained chilled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, and the external performance is relatively “hard”, so it is called chilled coils.

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.
