Product Description

Square/ Rectangular Tube
Pre-Galvanized: Pre-galvanized tube is made of hot dipped galvanized steel strip directly.
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 technelogy of electro galvanized tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.
