GI -Hot Dipped Galvanized/galvannel Steel Coils/Sheet

Introduction of GI-Hot Dipped Galvanized/Galvanneal Steel Coils/Sheet

Galvanized Steel coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.

Features of GI-Hot Dipped Galvanized/Galvanneal Steel Coils/Sheet

Strong corrosion resistance: The zinc layer on the surface of the galvanized coil has good corrosion resistance, which can effectively resist external factors such as wind, rain, acid rain erosion and so on.
Long service life: After galvanized coil, its service life can be more than twice as long as that of untreated steel, which greatly improves the service life of steel
High safety: Galvanized coil not only has good corrosion resistance and aesthetics, but also has good flame retardancy, which makes it widely used in the construction field.
Good environmental protection: During the production process of galvanized coils, certain waste gas, waste water and waste residues will be generated, but after treatment with modern technology, it can meet environmental protection standards and have no pollution to the environment.

Application of GI-Hot Dipped Galvanized/Galvanneal Steel Coils/Sheet

Galvanized steel coils(GI steel coils) can be used for making outside and inside automotive plates,
structual parts,reinforcements,home appliance and basic plate for coatting.Great quantities of them
have been used by main automobile makers

Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
