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.
Claims2
A cross-sectionally U-shaped profile comprising a base having a width and limbs integrally formed on said base;
- said limbs having a free end connectable to a covering part;
- said base having a reduced wall thickness;
- further comprising reinforcing impressions provided in said base in sections;
- said impressions extending transversely across said width.
A cross-sectionally U-shaped profile comprising a base and limbs integrally formed on said base;
- said limbs having a free end connectable to a covering part;
- said base having a reduced wall thickness;
- further comprising reinforcing impressions provided in said base in sections;
- said limbs being cross-sectionally thicker than said base;
- further comprising a deflection area where said limbs merge into said base;
- said limbs extending slightly into said deflection area with their thicker cross section;
- said impressions extending from a wall thickness of said deflection area.
