» Erw Hot-dip Galvanized Welded Steel Pipe
Product Description:
Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the
buildup of mineral deposits, thereby extending the pipe’s lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications.
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.
Electric Resistance Welded Steel Pipe
