Galvanized strip pipe:

1) The color of the galvanized strip pipe is a bit blue,

2) Weight: 6 meters long and 5.5 kg (corrosion resistance is slightly worse, the service life is shorter than that of hot-dip galvanized pipe, and the price is low and economical). The galvanized strip pipe is bright and reflective in white, with few snowflakes, and the two ends are clean and free of zinc warts.

Hot dip galvanized pipe:

1) The color of the hot-dip galvanized pipe is a little whitish,

2) Weight: 6 meters long and 6.5 kg (strong corrosion resistance, long service life, slightly higher price); hot-dip galvanized steel pipe is snow white but not shiny or reflective, with many snowflakes on the surface, and zinc nodules on both ends (condensation shaped zinc)

Hot-dip galvanized steel pipe (hot-dip galvanized steel pipe) is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. The supplied hot-dip galvanized steel pipes are first pickled. In order to remove the iron oxide on the surface of the steel pipes, after pickling, they are cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. Then into the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

The hot-dip galvanized pipe substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, it has strong corrosion resistance.
