Abstract
A floor structure is assembled from a plurality of extruded aluminum planks that extend laterally across the bed of a truck floor positioned on an undercarriage of a center beam and cross beams. The planks each have one or more ribs on their underside to strengthen the floor structure and provide a mechanical means for connecting adjacent planks together. Each plank is configured with a female end rib and a male end rib that interlock to restrain movement relative the adjacent planks in all directions except the lateral direction. Side rails are attached to the floor structure at the edges of the plank bed to prevent movement of the planks in the lateral direction.
