The hot dip galvanized hollow section pipe is broadly accepted in processing, manufacturing steel structure, scaffold and furniture, as well as delivering low pressure fluid. Its surface is generally hot dip galvanized or pre-galvanized. This product is originated from the hollow section tube through pickling firstly to get rid of the ferric oxide on the surface. Next comes the cleaning in the tank of aqueous ammonia chloride or zinc chloride or their mixed aqueous solution. At last, the hot dip galvanized hollow section pipe will be finished after dipping in the hot dip plating tank.
