A plastic pallet (10) in which a base structure (14) is posi- tioned beneath the plastic main body structure (12) of the pallet to discourage warpage and failure of the pallet especially in racked, loaded storage situations. The plastic main body structure (12) of the pallet includes a planar platform section (16) defining an upwardly facing load receiving surface and a plurality of legs (18) extending downwardly from the platform section to define tunnels therebe- tween for receipt of the forks of a forklift truck. The base structure includes a lower plastic sheet (44), an upper plastic sheet (42), and a plurality of tubular metallic beams (40) positioned in hollow ribs (14b) defined by the lower plastic sheet. The ribs (14b) are respective- ly secured to respective rows of legs (18) of the main body structure. Another embodiment of the base structure comprises a plurality of discrete individual beam structures (114 or 150) secured to rows of legs (118).
