ABSTRACT:
A hollow section for coupling to other sections and methods for the production and utilization thereof. Hollow sections are formed from strip or sheet material which are corrugated and then welded along a longitudinal seam. The thusly formed corrugated hollow sections are inserted into another section and flanged on or coupled thereto by smoothing or expanding the corrugations. The length of the corrugations is selected to be substantially equal to the circumference of the aperture into which the hollow section is coupled.
