A twin sheet pallet constructed by forming a lower polygonal plastic sheet to define an upwardly opening U-shaped groove around its periphery; forming an upper polygonal plastic sheet to define a plurality of circumferentially spaced upwardly opening U-shaped protrusions extending downwardly from the general plane of the sheet and sized to nest in the groove of the upper sheet; positioning the upper sheet over the lower sheet with the protrusions on the upper sheet nested at circumferentially spaced locations in the groove of the lower sheet; fusing the upper and lower sheets together to form double thickness U-shaped wall structures at the interfaces of the protrusions and the groove; and cutting aligned horizontally extending slots in the opposite sides of the U-shaped structures to allow entry of the forks of a forklift truck.
