Abstract: A cooling method of a travelling coated steel strip, exiting a hot-dip coating bath, including the steps of A) sucking a gas into a cooling device, B) filtering the sucked gas by a filtering system capturing at least 50% of the particles having a size of at least 2.5 µm, C) blowing, at a velocity comprised from 1 to 80 m.s-1, the sucked and filtered gas onto the coated steel strip.

Abstract: A method is provided. The method includes providing a steel substrate having two faces coated by dipping the substrate in a bath, altering layers of magnesium oxide or magnesium hydroxide formed on the outer surfaces of the metal coatings by applying mechanical forces, rinsing and drying the outer surfaces, applying a conversion solution on the outer surfaces and painting the outer surfaces of the metal coatings. A metal sheet is also provided.

Abstract: A method is provided. The method includes providing a steel substrate having two faces coated by dipping the substrate in a bath, altering layers of magnesium oxide or magnesium hydroxide formed on the outer surfaces of the metal coatings by applying an acid solution, optionally a conversion solution with a pH between 1 and 2, and/or mechanical forces, and painting the outer surfaces of the metal coatings. Additional methods and a metal sheet are also provided.
