Abstract:
An extruded profile comprises two transverse walls (2, 3; 2â€², 3â€²) and two side walls (5, 6; 5â€², 6â€²), wherein the transverse walls and the side walls are essentially symmetrical in relation to an axis of symmetry (4; 4â€²), two webs (7, 8; 7â€², 8â€²), arranged in the interior of the profile and substantially parallel to the side walls and extending between the transverse walls to define a plurality of chambers within the profile, wherein the transverse walls and the side walls (2, 3, 5, 6) form essentially an isosceles trapezoid, and the webs (7, 8) are arranged in the interior of the trapezoid, substantially parallel to the side walls (5, 6), and form the legs of the trapezoid and are symmetrically and wherein the webs (7, 8) form an accumulation of material (10) at their transition to the shorter trapezoid side (3).
