Galvanized Steel Coil for Rolling Shutter Door Back Plate

GI Galvanized Steel Coil is in order to prevent the surface of the steel plate from corrosion to extend its service life, the surface of the steel plate is coated with a layer of metallic zinc, this zinc-coated steel plate is called galvanized sheet. It is used cold rolled steel coil as substrates by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure. It has excellent corrosion resistance, paintability, and workability due to zinc's characteristics.

Application

 
Galvanized sheet steel products are mainly used in construction, light industry, automobile, agriculture, livestock and fishery and commercial industries. Among them, the construction industry is mainly used to manufacture corrosion-resistant industrial and civil building roof panels, roof grills, etc.; light industry with its manufacturing appliances shell, civil chimneys, kitchen utensils, etc., the automotive industry is mainly used for the manufacture of corrosion-resistant parts of the carcoil, etc.; agriculture, animal husbandry and fisheries are mainly used for food storage and transportation, meat and aquatic products, frozen processing appliances, etc.; business is mainly used for the storage and transportation of materials, packaging appliances, etc..

1.Steel plate for Car

The use of automotive plates must first be stamped and formed, and the steel plate is stamped into the required shape and size of the part.
Then spot welding, as an important welding method for thin plate connection, has a wide range of applications in the manufacturing industry, especially in the automotive industry.

2.Galvanized roof sheet
The performance requirements of galvanized roof panels mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating performance (coating type, coating thickness and coating adhesion)

3.Home appliance office sheet
Including air conditioners, washing machines, refrigerators, photocopiers, etc., household galvanized sheets are mainly used for general forming applications and stamping.

4.Basic raw material of prepainted coils
Another use of galvanized steel coils is to be used as the substrate of prepainted steel coils. prepainted steel coils have polyethylene coatings than galvanized coils and are more durable.
