Galvanized Steel Pipe
Galvanized steel pipe is the surface with hot-dip galvanized or electro-galvanized layer. Galvanized steel can increase corrosion resistance and prolong life. Galvanized steel pipe is widely used, except for water, gas, oil, generally low-pressure fluid line pipe, also used oi...
