ERW Galvanised Steel Tubing Pipe Q195 Rectangular Hollow GI 630mm
ERW Steel Square Tubing Galvanised Steel Pipe Q195 Erw Rectangular Steel Pipe Hollow GI Galvanized Steel Pipe
Detail:
The ERW (Electric Resistance Welded) manufacturing process involves forming a flat strip of steel into a square shape and then welding the edges together using electric resistance. This results in a strong and seamless square tubing that is suitable for various applications.
The galvanization of the steel pipe involves applying a protective zinc coating to the surface, enhancing its corrosion resistance and extending its lifespan. This galvanized coating provides excellent protection against rust and corrosion, making it ideal for outdoor and high-moisture environments.
The Q195 grade steel used in the manufacturing of the square tubing offers good strength and formability, making it suitable for structural applications. It is commonly used in construction projects, fencing, handrails, and other architectural applications.
