Abstract
Abstract A lightweight pallet having at least two sheets of flat material combined to provide a loading deck with supporting legs. The supporting legs are formed from the sheet material and comprise two panels cut from each sheet hingedly depending downwardly along a score line and adhesively interlocked in a manner to define a four-sided leg.
