Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure.
