ABSTRACT The invention relates to a component of a multilayer flat material construction, in particular for motor vehicles, whereby a number of preforms (1, 2) of flat material, of which at least one of the preforms (1) which forms an outside face of the component is of sheet metal, are perfectly jointed to one another by at least one type of joint element (3, 4) which has been produced in an extrusion or pressure-joint process. The invention is characterized in that for at least one of the types of joint-element (3) these each consist of two superposed, opposite edges of a square breach (31) formed by an H-shaped cutting punch which passes through all preforms (1, 2) on flanged edges (32, 33) provided on an external surface of the component, which are formed by the material sections of all preforms (1, 2) resulting from the H-shaped cutting punch.
