Hot Dip Galvanized Pipe
Hot-dip galvanised steel pipe, in order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanised. Galvanised steel pipe is divided into two kinds of hot-dip galvanised and electro-galvanised, hot-dip galvanised zinc coating is thick, electro-galvanised zinc cost is low, the surface is not very smooth.
