Abstract
A vehicle reinforcement beam is roll formed from a metal sheet to provide a multi-tubular reinforcement beam that includes two adjacent tubular sections that share a common center wall. The outer sections the metal sheet extend from opposing ends of the common center wall and are formed to enclose the adjacent tubular sections. An edge portion of the metal sheet that is bent to have a bend radius of about 3-9 mm, where the edge portions attach in abutting and continuous contact with the common center wall to form crevices between the adjacent tubular sections along the first and second faces. A weld is formed in each of the crevices to define crevice ribs in general alignment with and at each of the opposing first and second ends of the common center wall that are configured to improve bending strength and torsional strength of the reinforcement beam.
