The lamella profile (10) with two lamella walls (11; 12) which are connected to one another by a plurality of transverse walls (13; 14; 17; 18), in doing so forming one or more cavities. The top transverse wall (13) is adjoined by a hook strip (14). These profile parts are produced together in one piece from the same material. In addition to, or instead of, one or more transverse walls (15; 18) there is arranged in each case one web (21; 24) which consists of a material of higher strength and is provided along its edges with anchoring elements, preferably in the form of ribs (22; 23; 25; 26) which are at least partially formed by the material of the lamella walls (11; 12) and/or of the transverse walls (15; 18). The webs (21; 24) are expediently configured as lightweight-metal extruded profiles. <IMAGE>
