1.Black square&rectanhgular steel pipe:ERW steel tube

2.Pre-galvanized square&rectangular steel pipe: Pre-galvanized square/rectangular tube is made of hot dipped galvanized steel strip directly.

3.Hot dipped galvanizedsquare&rectangular steel pipe : Hot dipped galvanized square/rectangular tube owns thicker zinc coating than pre-galvanized square/rectangular tube. Black tubes will be dipped into zinc pool for galvanizing.

4.Electro galvanized square&rectangular steel pipe : The technology of electro galvanized square/rectangular tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.

5.Painted square&rectangular steel pipe:Painted square/rectangular to remove the rust and clean the oil first and then paint the required color paint.
