Galvanized coil, a thin steel sheet that is dipped in a bath of molten zinc to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, that is, the coiled steel plate is continuously dipped in the galvanizing tank with molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500ºC immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Galvanized coils can therefore be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils, which are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries. Their main features are: strong corrosion resistance, good surface quality, benefit from deep processing, economical and practical, etc.

Galvanized coil is a common steel product whose surface is galvanized to improve its resistance to corrosion and wear. So, what is the chemical composition of galvanized coil?
First of all, the base material of galvanized coil is ordinary carbon structural steel, and its main components are iron and carbon. In addition, it also contains a small amount of silicon, manganese, sulfur, phosphorus and other elements.
During the galvanizing process, galvanized coils are immersed in a solution containing zinc salts, and after a chemical reaction, a layer of zinc is formed on the surface. This zinc layer is mainly composed of an alloy of zinc and iron. The zinc content is usually between 50 and 60%, and the iron content is between 40 and 50%.
In addition to zinc and iron, some other compounds, such as zinc oxide and zinc carbonate, will also be produced. These compounds are mainly produced by the reaction of zinc with oxygen in the air.
Generally speaking, the chemical composition of galvanized coils is mainly iron, carbon, zinc and a small amount of other elements and compounds. These ingredients make galvanized coils have excellent corrosion resistance and wear resistance, and are one of the important materials widely used in construction, manufacturing and other fields.
