Hot-dip Galvanized Steel

Hot-dip Galvanized Steel

The properties of hot-dip galvanized steel are tough coating, completed protection, less maintenance and long life.

Hot-dip galvanized steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.
