A lightweight structure for a flatbed trailer having a cellular stiffening structure formed from a plurality of vertically arranged partitions which form a multiplicity of polygonal cells is disclosed. The cellular structure has the advantage of providing a strong lightweight structure which efficiently transmits load forces from the floor structure to the base upon which the wheels, suspension system, kingpin and landing gear are mounted. The resulting trailer has about a 4000 pound weight advantage over conventional steel frame trailers and about a 2500 pound weight advantage over conventional aluminum frame trailers, which translates directly into increased payload capacity as the trailer of the invention is capable of carrying loads up to the maximum legal weight limits in most states.
