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.
