Abstract: The invention relates to a method for the production of a metal panel, in which: at least one of the surfaces of a sheet of chromium (Cr) stainless steel, having a thickness of 0.1-2.00 mm, is subjected to a mechanical smoothing and/or glazing and/or grinding treatment until a surface roughness Ra of 0?06÷1 ?m is obtained with a pre-determined mark/drawing; a transparent primer/coating of adhesive or lacquer is applied to said surface; and the primer/coating is polymerised. The invention also relates to the metal panel obtained using the aforementioned method, comprising: a sheet of chromium (Cr) stainless steel, having a thickness of 0.1-2.00 mm and having at least one smoothed and/or glazed and/or ground surface with a roughness Ra of between 0?06÷1 ?m, said roughness having a pre-determined mark/drawing; and a cured, transparent primer/coating of adhesive or lacquer on the aforementioned surface.

Abstract: A metallic and magnetorheological multi-panel, which is constituted in a sandwich structure that consists of a core (2) that consists of a viscoelastic resin (2) of adhesive nature, in which are found, distributed in an isotropic or anisotropic manner with a proportion in volume of more than 5%; and Magnetorheological particles of ferromagnetic material and with sizes between 10 nm and 10?, said core (1) being arranged between a first skin (11) of metallic non-magnetic nature and a second skin (12) of metallic non-magnetic nature equal to or different from the first skin. The ratio of the thickness (Hn) of the core with respect to any of the thicknesses (H1), (H2) of the first (11) and second (12) skins is less than 0.1 and more than 0.01.
