A structural member formed from a billet, each member comprising a plurality of corrugated paperboard sheets bonded together with an adhesive and disposed between a core fibre layer, each core fibre layer comprising at least one ply of a fibreboard sheet, a pair of caps of a solid fibreboard sheet bonded to respective side faces of the paperboard sheet and to the respective edges of the core fibre layers. A method of manufacture is disclosed in which the billet is built up of corrugated paperboard sheets. The billet is then ripped into planks for use as a plank, board, or cleat, particularly as components for corrugated paperboard containers. A pallet made of planks and a pallet made of planar sheets cut from the billet are disclosed.

A pallet, comprising: at least two spaced-apart baseboards; at least two spaced-apart stringers disposed transverse to the baseboards, each stringer having end portions which overlap and connect to the baseboards; and at least two spaced-apart deckboards disposed transverse to the stringers and connected at overlapping portions on an upper surface of the stringers, the baseboards, stringers, and deckboards bonded together with adhesive at the overlapping portions, each baseboard, stringer, and deckboard comprising: a central web of a plurality of low density elongated corrugated paperboard sheets grouped together in a stack and bonded together with an adhesive, thereby providing an interior structure defining a cross-section shape of said web; and a beam-defining pair of caps, each cap being at least one ply of a high density fiberboard sheet bonded to a respected side of the stack of paperboard sheets; and one of the caps for each deckboard including extended portions that extend longitudinally from respective distal ends of the deckboard, whereby each of the extended portions, being folded perpendicular against a respective outer face of the stringer and secured thereto with adhesive, overlaps a joint between the deckboard and the stringer.
