Abstract:
1. A composite profile comprising: (1) an extruded aluminum alloy carrier profile comprising a rail head having a longitudinal axis B, the rail head comprises a surface and two longitudinal edges extending parallel to the longitudinal axis B and (2) a metal channel shaped profile strip comprising a base portion spanning the surface of the rail head and parallel side legs which lie on the longitudinal edges of the head rail, an insert rod is provided on each of the parallel side legs which lie on the longitudinal edges of the head rail and engage in lateral slots provided in the two longitudinal edges of the rail head, wherein the profile strip is attached to the carrier profile under mechanical pretension by way of a weld seam which contacts the rail head of the extruded aluminum alloy carrier profile, the insert rod is of approximately V-shaped cross-section comprising an outer channel arm having a longitudinal edge associated with an end face of the side legs of the profile strip and rigidly connected to the profile strip by the weld seam, wherein the weld seam has an approximately triangular cross-section with two sides at right angles to each other, wherein one side is formed integrally with the end face of the profile strip and the other side is formed integrally with the outer surface of the associated channel arm of the insert rod.
