A motor vehicle bodywork beam including a main reinforcement having a bottom, two side walls and two flanges substantially parallel to the bottom and a secondary reinforcement. The secondary reinforcement is fixed to the main reinforcement. The main reinforcement and secondary reinforcement are fixed at each side wall level, and of the side walls and/or bottom of the main and/or secondary reinforcement comprise a transition, such that at least a part of the bottom of the secondary reinforcement is in contact with a part of the bottom of the main reinforcement. The bodywork beam has at least one closed cell formed by the main reinforcement and a secondary reinforcement, and the cell has four linear segments formed by the main reinforcement and/or secondary reinforcement, three linear segments covering at least 50% of the corresponding dimension of the cell, so that two segments are oriented transversely to the bottom of the main reinforcement, and the other two segments are substantially perpendicular to said two first segments.
