What is welded galvanized square steel pipe?
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.
The pre-galvanized welded steel piperefers to welded tube which undergo degreasing,rush removal,phosphorization,zand drying processes before galvanization.The treatments before galvanization allow the product to be conveniently plated with a zinc coating,and also ensure uniform coating thickness,strong coating adhesion,and improved corrosion resistance
