The hot-dip galvanized layer is generally above 35 μm,and even up to 200 μm. The hot-dip galvanizing has a good covering ability, the coating is dense, and there is no organic matter inclusion. The corrosion resistance of hot dip galvanizing is much higher than that of cold galvanizing.
Pre-Galvanized Steel Pipe
The Pre galvanized layer is generally from5 μm to 25 μm, 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
