Galvanized coils are made by dipping steel sheets into a coating bath containing molten zinc and causing a layer of zinc to adhere to the sheet surfaces. Galvanized coils are mainly produced by a continuous galvanizing process, i.e., coils of steel sheets are continuously dipped in a coating bath containing molten zinc to form galvanized steel sheets.
Alloyed galvanized steel sheets: They are also made by hot dipping. The difference lies in that they are heated to about 500°C immediately after leaving the bath to cause them to form a zinc-iron alloy coating.
They are processed in different forms depending on the purpose. Galvanized coils are the most widely used in construction and light industry, accounting for about one-third of their total applications.
Galvanized coils are a type of steel that has been treated with corrosion protection. They are widely used in our life, with their applications ranging from tables and chairs to large buildings.
Galvanized coils are mainly produced by a continuous galvanizing process, i.e., coils of steel sheets are continuously dipped in a coating bath containing molten zinc to form galvanized steel sheets.
Cold-rolled coils are commonly used in the steel industry and are different from hot-rolled coils. They are steel strips made by rolling the rolls directly until they have a certain thickness at normal temperature and winding the rolled rolls into complete coils with a winding machine.
Cold rolling can turn ordinary steel into high-strength wear-resistant steel, high-strength low-alloy steel, high-strength stainless steel, etc. The reason is that cold rolling can rolling refine the crystals of metal and improves its compactness, thereby increasing its hardness, strength and ductility.
