Product details
GALVANIZED STEEL TUBE
introduction
Galvanized welded steel pipe is divided into hot galvanized steel pipe and electric galvanized steel pipe as a different process, galvanized steel pipe has strength for uniform coating, strong adhesion and long service life than later, electric galvanized steel pipe that has a rough surface and less corrosion resistance. But it's lower production cost.
