a plastic pallet is formed of two identical interlocking and mating components joined along a common center plane . at least one internal component is stepped , with the steps of two components fitting together to interlock the two components together when they are assembled . the two components include integrally formed plural spaced apart deck boards , tiedown passages , and fork lift slots or passages in each of the four sides of the rectangular assembly . a generally rectangular peripheral structure and a cruciform central structure are provided for additional reinforcement . the two halves are bolted together for use , with an assembled pallet being easily disassembled to remove a damaged component for replacement . as the two components comprising the present pallet are identical , they may be cast or formed in a single mold , or in identical molds , with any half pallet component serving as a replacement . the components are preferably formed of thermoplastic material which may be recycled if damaged or otherwise rendered unsuitable for further use .
