A rectangular pallet that is symmetrical about its two major axes. The pallet comprises a first plastics shell and a second plastics shell. The first plastics shell is formed with a flat rim, nine or more ground engaging feet subtending below the level of the rim, the feet being arranged in respective parallel spaced apart beams extending from front to back. The first plastics shell also has plural channels running from side to side intersecting the beams running from front to back to define the feet. The second plastics shell is essentially flat and formed with a flat rim. An internal network of partitions extends between the first and second plastics shells. The rims of the first and second plastics shells are sealed to each other to form a clam and to enclose the network of partitions within the clam. In other aspects, the invention concerns a method and a system for forming the pallet.
