Abstract

Procedure for coating a metal object, for example a wire, a strap or a steel wire mesh or network, by immersion in molten zinc, causing that object, during this process, to emerge from the molten zinc bath through a layer of round granules inert to the molten zinc and located on the surface of the bath, which is maintained under a non-oxidizing atmosphere, in the area in which the object emerges, characterized in said procedure in which the emergency site, at least one of the Fluids adjacent to the external surface of the liquid zinc layer adhered to the object are provided with a material, other than hydrogen sulfide, that at the emergency temperature and in the presence of a zinc oxide film located on said surface is unstable and that, in addition, under the aforementioned conditions, is capable of reducing zinc oxide.
