A sandwich-type structure comprises two external metal plates and an inner core held between the two external plates and constituted by a metallic screen netting or grid. In order to be easily stamped said structure comprises, between the plates, a layer of adhesive making the bond between the plates and the core. This adhesive is located only inside the meshes of the core, whereas the contact zones between the core and the plates are left free of adhesive. In the case where all three elements are in weldable metal, spot welding remains possible, if necessary, on the periphery or through the mass, these weld points being in this latter case sufficiently far apart to allow a geometrical deformation of the meshes of the metallic netting or grid constituting the core. |
