Surface Finish
 
* Brighten : Brighten steel pipe is made of brighten annealed steel strip 
( a kind of material corresponding to CR.) Similar with black tube made of cold rolled coil, 
brighten steel pipe keeps the original brighten color of steel.
 
* 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.
 
* 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.
 
* Pre-galvanized: Pre-galvanized tube is made of hot dipped galvanized steel strip directly
 
* Painted :Painted pipe to remove the rust and clean the oil first and then paint the required 
color paint.
