Galvanized steel pipe

Galvanized pipe, also known as galvanized steel pipe, divided into two kinds of hot galvanized and electric galvanized, hot galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages.The cost of electric galvanized is low, the surface is not very smooth, and the corrosion resistance of its own is much worse than that of hot dip galvanizing pipe.Often said galvanized pipe is now mainly used for conveying gas, heating.
