摘要： A roof rail for vehicles with a tubular gallery rod (1) and a pair of rail feet (2) which are arranged at its ends, are supported on a vehicle's roof (4). The rail feet (2) are each formed from the same length of material as the gallery rod (1) and consist of bent and flared end sections of the gallery rod (1). The gallery rod (1) has a continuously increasing cross section proceeding from the transition region of one rail foot (2) up to the transition region into the other rail foot (2). A manufacturing process for the roof rail is also disclosed in which a length of extruded material having an expansion fold is formed with arcing end portions. The length of material is then placed in a molding tool and pressurized to expand the material such that it forms a roof rail.
