1. A twin sheet plastic sheet comprising:

  • (a) a lower polygonal plastic sheet defining an upwardly opening continuous U-shaped substantially constant depth groove extending in a closed loop around the total periphery of said lower sheet to define a continuous circumferential footprint on the undersurface of said lower sheet;

    (b) an upper polygonal plastic sheet defining a plurality of circumferentially spaced upwardly opening U-shaped protrusions extending downwardly from the general plane of the sheet and sized to nest within the groove of the lower sheet, whereby said upper sheet is positioned over said lower sheet with said protrusions positioned at circumferentially spaced locations in said groove and said sheets are fused together to form double thickness U-shaped wall structures at the interfaces of the protrusions and the groove and a continuous circumferential footprint beneath said pallet to facilitate movement of said pallet over various transfer surfaces and devices; and

    (c) aligned horizontally extending slots in the opposite sides of said U-shaped wall structures to allow passing of the forks of a forklift truck.
