A frame rail for a vehicle has a pair of elongated structural members, each one of the pair of elongated structural members having flanges protruding from lateral edges thereof. The flanges of one of the pair of elongated structural members extend in a direction toward the flanges of the other one of the pair of elongated structural members. The frame rail also has first and second metallic web panels interconnecting the pair of elongated structural members. Overall, the frame rail has a box beam structure, wherein at least a major portion of each one of the first and second metallic web panels has a material thickness that is less than a material thickness of at least a major portion of each one of the pair of elongated structural members. |
