The aim of the invention is to provide a method for producing a metal sheet (108), especially a steel sheet, at least one surface (136) of which is provided with a surface structure that provides as structural elements (128) depressions and/or elevations, and which metal sheet (108) is substantially resistant to scratches and finger prints. The inventive method is characterized by configuring the surface structure as a random microstructure.
L'invention concerne un procédé de production d'une tôle métallique (108), notamment d'une tôle d'acier, consistant à doter au moins une surface (136) de la tôle métallique d'une structure superficielle comportant, comme éléments structurels (128), des creux et/ou des bosses. L'invention vise à proposer un procédé de ce type qui permette d'obtenir une tôle métallique (108) résistante aux éraflures et aux traces de doigts. A cet effet, la structure superficielle est conçue sous forme de microstructure irrégulière.
