EN39 Galvanized Steel Pipe

EN39 galvanized steel pipe is refers to loose steel tubes for tube and coupler scaffolds. This European Standard specifies the requirements for non-alloy steel tubes for use with EN74 couplers in the construction of false work and working scaffolds.

Hot dip galvanized steel pipe with pickling is produced by first removing iron oxide from the steel tube's surface, followed by acid cleaning, ammonium chloride or zinc chloride tank cleaning, or ammonium chloride and zinc chloride mixed aqueous solution tank cleaning, and then sending to the hot dip plating tank. Layer thickness of hot dipped galvanized zinc, coating homogeneity, strong adhesion, extended service life, and so on. The formation of corrosion resistance of the structure compact zinc alloy layer on a steel substrate with molten electrolyte solution in a complex physical and chemical reaction. Fusion of pure zinc layer, alloy layer, and steel substrate. So there's the corrosion resistance.
