JIS G3302 SGCH Anti Impact Galvanized Steel Coil Oiled Surface For Civil Chimney

Galvanized Steel Sheet , Civil Chimney, Kitchen Appliance

Description:

One of the most common ways of making steel resist rust is by combining (alloying) it with a metal that is less likely to corrode: zinc. When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel. Therefore, the zinc isn't exactly a sealer, like paint, because it doesn't just coat the other metal; it actually permanently becomes a part of it. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel.

This process, known as hot-dipped galvanization, is one of the most common methods of making galvanized steel, but it's not the only one. Continuous sheet galvanizing runs a steel sheet or wire through molten zinc; it's also a form of hot-dipping, but leaves a thinner layer of the protective metal. Steel can also be painted or sprayed with zinc, although neither method creates the strong bond that hot-dipping does. Electrogalvanizing or electroplating uses electricity to create the bond between the two metals, which results in relatively thin layer of zinc.
