Hot-dip Galvanized ERW Steel Pipe
One of the most widely used materials on Earth, steel provides outstanding strength, toughness, and durability. Steel pipe is a versatile, cost effective solution for a broad range of applications, including:
Construction and architecture
Water/sewer plumbing
Pipeline systems
Gas and fluid transfer lines
Industrial equipment manufacturing
Oil and gas processing
Galvanized ERW Steel Pipe Advantage
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.
