Profiled element and method for producing a profiled element

Abstract

The invention relates to a profiled element with an elongated profiled body that consists of metal or plastic in particular. The profiled body comprises at least two separately designed longitudinal portions, each longitudinal portion comprising a meandering longitudinal edge and a rectilinear longitudinal edge that lies opposite the meandering longitudinal edge. The longitudinal portions are connected to each other by the rectilinear longitudinal edges. The invention further relates to such a profiled element in which the longitudinal portions can be designed separately or as a single piece, said profiled body having a substantially U- or V-shaped cross-section with two profiled limbs and a profiled connecting piece that connects the profiled limbs. The profiled limbs are formed by the bent longitudinal portion regions that comprise meandering longitudinal edges, and the respective profiled limbs are designed so as to be doubled-walled with an outer wall and an inner wall, which faces the interior of the U- or V-shaped cross-section, in at least some regions, said meandering longitudinal edges running in the inner walls of the double-walled profiled limbs at least along some sections. The invention further relates to a method for producing such profiled elements.
