Home > galvanized steel pipe
The thin zinc layer on steel provides resistance to corrosion by two mechanisms: First, it acts as a sacrificial anode when attached to steel because it will corrode preferentially under corrosive conditions thereby protecting the underlying steel. Second, in the presence of moisture zinc reacts with oxygen and carbon dioxide from the air to form a protective coating of zinc carbonate (passivation) when it dries out. Under atmospheric exposure when it can dry out, galvanized steel works quite well on guard rails, corrugated roofing, flag poles, and street signs because it forms a protective coating of zinc carbonate.
Galvanized steel pipes are dipped into a protective zinc coating to protect the pipes from corrosion in wet environments. In addition, galvanized pipes are a lower cost alternative to steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.
