Abstract: A coated metallic substrate including at least a first coating consisting of aluminum is provided. The first coating has a thickness between 1.0 and 4.5 μm and is directly topped by a second coating based on zinc, such second coating having a thickness between 1.5 and 9.0 μm. The thickness ratio of the first coating with respect to the second coating is between 0.2 and 1.2.
