摘要： A metal sheet is provided. The metal sheet includes a substrate having two faces, each face hot dip coated with a metal coating of zinc, aluminum and magnesium. The metal coatings include between 0.1 and 20 wt % of aluminum and 0.1 and 10 wt % of magnesium. Layers of magnesium oxide or magnesium hydroxide are formed on outer surfaces of the metal coatings. The layers are altered by applying an acid solution on the outer surfaces of the metal coatings or by applying mechanical forces using a roller leveler, a brushing device, or a shot-blasting device on the outer surfaces of the metal coatings. The metal sheet also includes a layer of oil deposited directly on the outer surfaces of the metal coatings.

摘要： The present invention provides a metal sheet including a steel substrate coated on at least one face with a coating including from 0.1 to 20% by weight of magnesium, optionally from 0.1 to 20% by weight of aluminum, the balance being zinc, potential impurities linked to the method and optionally one or more additional elements selected from among Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni, Zr and Bi, the content by weight of each additional element being less than 0.3%. The coating itself is covered by a layer, based on zinc hydroxychloride, having a chlorine coating weight of at least 1 mg/m2. The layer does not include hydrozincite or mixed hydroxycarbonates of zinc and aluminum or water-soluble compounds of sodium or potassium. The present invention also provides a method to obtain the metal sheet.
