ABSTRACT:
A support rail for a vehicle has an A-pillar portion and a roof rail portion. The roof rail and A-pillar are formed with a tubular body portion and longitudinally extending support flanges. The support flanges are formed by pinching the blank during the hydroforming process to provide a double thickness flange. A windshield support flange, roof support flange and door opening flange are formed to extend outwardly from the tubular body portion. Front and rear tube connectors include blind openings or notches to facilitate welding.
