Corrosion of galvanized steel
Webreduce the corrosion rate of the steel. The zinc coating is thus “sacrificed” to prevent corrosion of the steel. Galvanizing protects the steel even when the coating is attacked. The appearance of white powder on steel conduit or EMT is evidence that the zinc coating is doing its job. When steel or iron rusts, the oxide is red.
