Hot dip zinc square pipe tube
            After hot-dip galvanizing, a zinc coating is formed on the surface, which can effectively prevent rust and corrosion of steel and extend the service life of the pipe. Surface treatments include galvanizing, oiling, color spray painting, 3PE, etc. or other anti-corrosion treatments. The size range is wide, such as theoretical size of 20 - 406mm (1/2 inch - 16 inches), thickness of 1.2 - 15.7mm, and length can be customized according to demand (any length less than 16 meters), which can meet the needs of different projects.
