Galvanized Steel Pipe
1.(a)Hot dipped galvanized: Hot dipped galvanized tube owns thicker zinc coating than pre-galvanized tube. Black tubes will be dipped into zinc pool for galvanizing.
(b)Electro galvanized: The technology of electro galvanized tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.
(c)Pre-galvanized: Pre-galvanized tube is made of hot dipped galvanized steel strip directly
(d)Painted :Painted pipe to remove the rust and clean the oil first and then paint the required color paint.
2.Zinc coating
pre galvanized steel pipe: 60-150g/m2
hot dipped galvanized steel pipe:200-400g/m2
