    摘要: According to the invention, the long product to be coated (in particular a moving steel wire being) is dipped into a zinc alloy bath and, upon the exit thereof from the bath, the coated product is cooled, characterized in that said zinc alloy bath includes, in weight percent, 4 to 8% of aluminum and 0.2 to 0.7% of magnesium, and in that said cooling is supervised so as to impart, to said metal coating, a homogeneous microstructure having a phase portion β greater than around 25 vol %. The resulting coated product has high resistance to corrosion, in particular in a saline medium, and at the same time has a high metallurgical quality and protected wear properties, and the implementation of the method for producing same does not present any particular difficulties with regard to the known dip coating techniques.
