Welded/ERW Hot Dipped Galvanized Steel Pipe Q235 Q345 Square 30*30 50*50 100*100 Hot Rolled Tube

Detail:

The welded/ERW hot dipped galvanized steel pipe is a high-quality steel pipe that has undergone a galvanization process, providing enhanced corrosion resistance and durability. It is manufactured using the Electric Resistance Welding (ERW) method, ensuring a strong and seamless construction.

During the galvanization process, the steel pipe is immersed in a bath of molten zinc, forming a protective zinc coating on its surface. This coating acts as a barrier against corrosion, making the pipe suitable for outdoor and corrosive environments. The hot-dipped galvanization ensures a uniform and robust zinc coating that adheres tightly to the steel surface.
