The galvanized steel sheet is a metal sheet that has been coated with a layer of zinc through a process called galvanization. Galvanization involves immersing the steel sheet in molten zinc or applying a zinc coating through electroplating or other methods.
Galvanizing can effectively prevent corrosion of metal steel sheets and extend their service life. The amount of galvanizing is a commonly used and effective method to indicate the thickness of the zinc layer of galvanized sheets. Hot-dip galvanizing coats significantly more zinc than cold-dip galvanizing, so it is resistant to corrosion. Good corrosion performance. The quality requirements for high-quality galvanized sheets include specifications, dimensions, surface, galvanizing amount, chemical composition, shape, mechanical properties and packaging. Regarding the national standard for galvanized steel sheets, please refer to the new national standard for galvanized steel sheets GB-T/2518-2008. The requirements for the chemical composition of galvanized sheet substrates vary from country to country. National standards generally test the content of carbon, manganese, phosphorus, sulfur, and silicon.
The biggest advantages of the coating of metal galvanized sheets are excellent corrosion resistance, paintability, decoration and good formability.
