A longitudinally extending extruded aluminum bumper is constructed and used in a bumper assembly to protect a vehicle from impact. The bumper includes a three wall design, formed by an integrally formed top wall and a bottom wall interconnected by a front vertically extending wall. The top and bottom walls have open ends that are spaced relative to one another to form a longitudinally extending, open-ended channel therebetween. Upwardly extending and downwardly extending flanges are integrally formed with front vertically extending wall and the top and bottom walls of the bumper. The extruded bumper can be attached directly to an end of a vehicle. Impact absorption devices can also be inserted into the longitudinally extending channel of the bumper and abut against the front vertical wall. Welds can be provided in a non-planar manner to connect the impact absorption devices to the bumper.
