A platform trailer comprises a plurality of extruded aluminum floor boards, which are approximately four inches in thickness centrally of the trailer. The floor boards transversely outward of the center portion taper to a thickness of approximately 21/2 inches at the side edges of the trailer platforms. The floor boards have top and bottom panels which are joined by angularly disposed webs. The floor boards have mating welded edges that are joined to form a continuous horizontal substantially planar platform. A floor board spaced inwardly from each side edge of the platform has a downwardly extending web portion on the bottom thereof to which the web portion of an inverted T-shaped longitudinal frame member is secured. Pockets are welded in openings through the top and bottom panels of the transversely outermost floor boards for the acceptance of stakes in any desired longitudinally spaced relation. The transversely outermost floor boards are provided with openings spaced along the length thereof for access to a wood filler member secured therein to permit nailing to the platform.

A cargo container formed of extruded light metal framing members and cooperating panels is made in subassemblies composed of parts which are secured together primarily by riveting, the subassemblies also being secured to one another primarily by riveting, although certain key fastenings are made by welding, and parts are limitedly telescopable prior to welding, to accommodate variations resulting from manufacturing tolerances. Fastening means for securing cargo within the container, and for securing the container against displacement in a vehicle during transportation, are integrated with rigid framing elements.

The disclosure relates to a solution to the problem of distortion and deformation of the floor of a lightweight shipping container. Heretofore, relatively heavy loading of lightweight shipping containers has caused the floor thereof to deflect sufficiently to distort the side walls and end walls of the container and often permanently deform the floor. In practicing the present invention, the floor boards adjacent the side walls of the container are modified so as to increase the resistance thereof to shear loads and thus minimize deflection.
