Abstract: A modular food display case system permits a particular display case arrangement to be easily customized from a basic design. A plurality of modular bed sections, which are pre-manufactured from a lightweight composite honeycomb material, are used as the basic building blocks of the customized display case, and are arranged end to end. Their lengths may be cut and angled as desired to further customize the arrangement of the customized display case. Partitions divide different temperature-controlled zones within the display case, and may be positioned anywhere along the length of the case, according to the specific arrangement and lengths of hot, cold, and dry (ambient temperature) zones employed, without regard to the ends of the case or the location of joints separating each of the bed sections.
