Galvanized steel pipes are carbon steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. The zinc provides a protective barrier against corrosion when exposed to the outdoor environmental elements and indoor humidity.
Galvanized pipes are a cheaper alternative to stainless steel pipes, while maintaining comparable strength and protection against rust.
