A plastic pallet comprising an upper plastic sheet and a lower plastic sheet. The lower sheet has a generally rectangular configuration, including sidewalls and end walls, and includes a plurality of separate parallel upwardly opening longitudinally extending U-shaped grooves extending from end to end of the sheet and a plurality of downwardly opening U-shaped grooves interspersed between the upwardly opening grooves and opening in the end walls of the sheet. The upper sheet defines a top wall and a plurality of upwardly opening U-shaped protrusions extending downwardly from the top wall and sized to nest within the upwardly opening grooves of the lower sheet, whereby the sheets may be fused together to form double thickness U-shaped wall structures at the interfaces of the protrusions and the upwardly opening grooves. The pallet further includes a pair of longitudinally extending metallic beams positioned between the upper and lower sheets.
