A method for depositing composite metallic coatings on a metallic strip, involves bringing in contact with a metallic coating, deposited on the strip by using a continuous dip coating method, before setting of the metallic coating, an additive metal powder in suspension in a gaseous jet. The melting point of the additive metal powder is higher than that of the base coating metal, so that the additive metal powder particles penetrate into the coating in order to obtain a composite structure imparting to the strip an increased corrosion resistance, compared to that provided by a base coating free from additive metal.
