Abstract: The elongated box frame structure of the present invention comprises a plurality of frame segments attached to at least one end piece. Preferably, two end pieces are attached, one at each end of the plurality of frame segments. The plurality of frame segments are attached to the end piece such that a column-like structure is formed. The inner space defined within the frame segments can be substantially free of webbing. Structural strength and stability is generally achieved by the bridging support of the attached end pieces.
