Product Description

Hollow Section Galvanized Steel Seamless Round Tube Pipe Hot Dipped Zinc Coating En10255 Cold Rolled /Gi Galvanized Welded Square Steel Pipe for Scaffolding
1.Black steel pipe:ERW steel tube
2.Pre galvanized steel pipe: Pre-galvanized tube is made of hot dipped galvanized steel strip directly.
3.Hot dipped galvanized steel pipe : Hot dipped galvanized tube owns thicker zinc coating than pre-galvanized tube. Black tubes will be dipped into zinc pool for galvanizing.
4.Electro galvanized steel pipe : 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.
5.Painted steel pipe:Painted to remove the rust and clean the oil first and then paint the required color paint.
