Abstract

The disclosure describes a preferred form of a method of making a pallet by forming legs on a sheet of material and attaching a second sheet to the marginal edges of the first sheet and filling the space between the sheets and the legs with a foamable plastic material such as polyurethane, or the like. The sheets may be any vacuum formable material such as thermoformable plastic. They could also be other materials that may be formed or molded into sheets with legs, such as cardboard, metal, wood, or other suitable structural materials.
