galvanized steel

iran galvanized steel:

galvanized Steel is created through the hot-dip galvanizing process whereby carbon steel coil is submerged in a bath of molten zinc. The steel coil emerges with a metallic coating of zinc on both sides of the strip. Galvanizing protects the carbon steel in two ways. First, the zinc coating provides a continuous, impervious metallic barrier that does not allow moisture to contact the steel. Without moisture, there is no corrosion. Secondly, when the base steel is exposed, such as with a cut edge or scratch, the steel is protected by the sacrificial corrosion of the zinc coating adjacent to the steel.
