Product:Excellent corrosion resistance Zn(0) Hot DIP Galvanized Steel Pipe
Decriptions
Galvanized round tubing is a kind of steel pipe with a circular cross-section. It is more durable than carbon steel tubes but more cost-effective than stainless tubes. Besides, round tubing has one continuous surface with no edges, which makes it more resistant to flexing and torsional twisting under weight and pressure. It is commonly used for transporting fluid, such as oil, water, gas, etc.
