A process for producing an integrated plastic unit from heated thermoplastic sheet material, such as polyethylene. The heated thermoplastic sheet material is placed over reinforcing forming members disposed on spacers which space the reinforcing forming members from the face of a mold, and the reinforcing members extend over substantially the entire face of the mold. The heated sheet material is then forced over the reinforcing forming members and over the face of the mold, such as by vacuum forming, to provide a generally flat surface extending in one plane and a bridging or web surface encapsulating the reinforcing forming members to provide a fused ribbed substructure of the thermoplastic sheet material reinforced by the forming members extending in a plane generally perpendicular to the flat surface. The reinforcing forming members may be metal members such as bars, wire, strip or rods, arranged in a grid-like network. The mold may be flat or of bowed configuration. The product is particularly utilized as a pallet for transportation by forklift trucks in which event legs are provided for the unit.
