Galvanized Zinc Corrugated Steel cold rolled Steel Coil

It 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 zinc Steel Sheet steel coil Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides.

SS400 zinc Cold Rolled Steel 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.

The cold plate is a hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no scale is produced, therefore, the cold plate has good surface quality and high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled steel sheets, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel

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).

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. Hard-rolled coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.

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

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; The light industry uses it to manufacture household appliance shells, civil chimneys, kitchen appliances, etc. the automobile industry is mainly used to manufacture corrosion-resistant parts of cars, etc; Agriculture, animal husbandry and fishery are mainly used as tools for grain storage and transportation, frozen processing of meat and aquatic products, etc; Commerce is mainly used as storage and transportation of materials, packaging tools, etc.

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.
