A lightweight beam is formed from a single sheet of cardboard, and a pallet is constructed using the lightweight beam. A number of folds are pre-scored on the sheet of cardboard, forming a diagonal panel, a securable panel on one side of the diagonal panel, and a plurality of structural panels on the other side of the panel. The beam is assembled by folding the securable panel in a first direction and then folding the structural panels in a second direction using a rolling action, thus simplifying the assembly of the beam. The beam has double-walled sides to provide strength in the vertical direction in the pallet. The beam is provided with interlocking tabs which prevent the beam from disassembling, and which avoid the need for adhesives.
