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 platform trailer having a platform constructed from a plurality of floor boards at least two of which are of different types of extrusions joined in alternately disposed relation, the floor board of one type having spaced top and bottom panels joined by angularly disposed webs forming a triangle, the base of which forms said top panel and the apex therebelow being connected to the center of said bottom panel, the other type of floor board has top and bottom panels constructed from a central upright triangle and two inverted triangles transversely outward thereof with the side webs of said inverted triangles forming triangles with the webs of said one type of floor boards to have the top and bottom panels of the platform spaced by the angularly disposed webs when the said one and other types of floor boards are in aligned abutted, welded relation.
