Abstract: Preformed modules for making pallets include basic crossbar profiles and additional long and short crossbar profiles, basic and additional board profiles, and connection fittings. Each crossbar profile includes a preformed body having a cross section with a framework of laminar baffles, which define a plurality of cells, a perimetric covering, and longitudinally extending engagement elements. Each of the basic and additional board profiles is laminated and includes a plurality of cells, a perimetric covering, and at least one longitudinal engagement element on the perimetric cover. The crossbar profiles support the board profiles by means of the connection fittings. A pallet includes some or all of the modules described above.
