Abstract: A reinforced pallet (10) includes an upper surface (11) and a pair of opposing support sides (14, 15). The pallet (10) also includes at least one reinforcing bar channel (50) and a reinforcing bar (40) received within reinforcing bar channel (50). A twin-sheet pallet (10) is formed vacuum-forming a first plastic sheet (33a) to a first mold section (30) and a second plastic sheet (33b) to a second mold sheet (31), wherein a preselected portion of the second mold section (31) is sealed such that the second plastic sheet (33b) is not vacuum-formed. The mold sections (30, 31) are then moved together and the sheets (33a, 33b) are compressed together at preselected locations. A thermoformed, plastic pallet (10) for bearing and positioning a load, also includes and a retaining wall assembly (90) carried by the upper surface (11); the retaining wall assembly (90) including a wall-receiving slot (91) in the upper surface (11) and a retaining wall (92) received and positioned within the slot (91).
