A metal laminate assembly comprising at least a first metal sheet and a second metal sheet joined to each other at a first and a second straight edge respectively by means of an irreversible mechanical coupling using the method of claim 1 for joining metal sheets, each metal sheet having a respective upper surface and a respective lower surface opposite each other in the direction of the thickness, wherein said irreversible mechanical coupling is defined by:
a first edge flap of said first metal sheet that extends along said first edge of said first metal sheet and is bent against the lower surface of said first sheet;
a second edge flap of said second metal sheet that extends along said second edge of said second sheet and rests on the lower surface of said first metal sheet, interposed between said first edge flap and said lower surface of said first metal sheet, wherein said second flap is connected to the rest of said second metal sheet by a bent portion of said second metal sheet, said bent portion being bent around said first flap, interposing itself between said first flap and said second flap.
