75x75 Galvanized Steel Square Tube 20x20mm Pre Galvanized Square Steel Pipe
Galvanized steel pipe is divided into two kinds, hot dip galvanized and electric galvanized. Hot dip galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. Electrogalvanizing itself has better corrosion resistance. Galvanized steel pipe mainly used for conveying gas and heating. |
