Zinc metal coating is widely used as external and internal protection of conductive installation steel pipes for the transport of sanitary drinking water. It is also used in light constructions for construction, electricity, agriculture, traffic, etc.

When exposed to air, zinc forms a carbonate, which stops further corrosion. It is applied by immersing steel pipes in molten zinc with a purity of 99.995%. Preparation of the pipe surface is carried out by degreasing in industrial detergents, pickling in dilute sulfuric acid and fluxing in zinc and ammonium chloride. Then the pipes are immersed in a bath of molten zinc at approx. 445˚C, where they remain for a certain time to obtain the intended thickness of the coating.
