A multi-tubular beam for a vehicle, such as a vehicle structure or a bumper reinforcement, includes an elongated beam formed with a metal sheet. The metal sheet has a central section and outer sections extending along a length of the metal sheet. The outer sections are disposed in opposing directions from the outer edges of the central section to provide adjacent first and second tubular portions. The central section forms a common center wall between the adjacent first and second tubular portions. A first edge portion of the metal sheet is disposed along and in parallel alignment with the center wall. The first edge portion is attached to the center wall at a first weld joint to form the first tubular portion. The first weld joint includes a weld material that extends through a thickness of the center wall and into a thickness of the first edge portion.
