Abstract

The invention relates to an extruded conduit profile which has a U-shaped cross-section and is comprised of a base and limbs, said limbs being shaped on the base as one piece. The profile also has a covering part which can be connected to one free end of the limb. The invention provides a material-saving production of conduit profiles while completely adhering to the required stability at the same time. To this end, at least the wall thickness of the base of the U-shaped conduit profile is reduced, and impressions which reinforce are placed in a section by section manner inside said base which has a reduced wall thickness.
