Hot-dip galvanized pipe is pickled to remove iron oxide, cleaned in ammonium chloride and zinc chloride solution, and then hot-dip plated. This process creates a corrosion-resistant zinc-iron alloy layer integrated with the steel substrate, providing exceptional durability and protection against environmental factors.

The zinc structure forms a dense quaternary crystal barrier, effectively preventing corrosion penetration and ensuring a longer service life for the steel plate.

Our quality control includes visual inspection for smoothness, thickness measurement using professional tools, and leak plating repairs to ensure no more than 0.5% leakage surface area.

Used extensively in curtain walls, steel construction projects, shipbuilding, solar power brackets, and the automobile industry.
