A metal piece for a motor vehicle has a generally elongated shape according to a longitudinal direction. The piece includes at least one edge extending according to the longitudinal direction, at the intersection of two walls of the piece, and at least one area having a mechanical strength lower than the rest of the body of the piece, wherein the at least one area is formed through local thermal control of the piece. The lower mechanical strength area of the piece undulates along the edge, extending alternatingly along each of the walls forming the edge. A method for making the metal piece is also disclosed.
