The present disclosure relates to a panel for vehicle comprising a coated steel sheet locally reinforced with a patch, which is coated with a metal coating. The present disclosure addresses a problem observed with the metal coating which is prone to delamination of paint layers around the patch, and thus has corrosion issues. The solution described is a panel comprising a steel sheet having a metallic coating which is configured to prevent delamination of paint layers around the patch. In a particular embodiment, the steel sheet includes a zinc aluminum magnesium coating, which does not have corrosion or paint delamination issues when locally reinforced by the patch.
L'invention concerne un panneau pour véhicule comprenant une tôle d'acier revêtue localement renforcée, un procédé de préparation du panneau et l'utilisation de ce panneau.
