Abstract: A method for producing a metal sheet is provided. The method includes providing a steel substrate having two faces coated by dipping the substrate in a bath, applying an acid solution with a pH comprised between 1 and 4 on the outer surfaces of the metal coatings and applying an adhesive locally on at least one outer surface of a metal coating.

Abstract: A metal sheet assembly is provided. The metal sheet assembly includes a first metal sheet having two faces, each face is hot dip coated with a metal coating comprising zinc, from 0.7 to 6 wt % of aluminum and from 0.1 to 10 wt % of magnesium. An acid solution with a pH from 1 to 4 is applied to outer surfaces of the metal coatings. An adhesive locally is applied on at least one acid solution-treated outer surface of the metal coating, the adhesive is selected from structural, reinforced structural or semi-structural adhesives, sealing putties and wedging putties. A second metal sheet is assembled to the first metal sheet via the adhesive.
