摘要:
A method for producing a metal sheet is provided. The method includes providing a steel substrate having two faces, depositing a metal coating on each face by dipping the substrate in a bath, cooling the metal coatings, altering layers of magnesium oxide or magnesium hydroxide formed on the outer surfaces of the metal coatings, and depositing a layer of oil on the outer surfaces of the metal coatings.
