A structural member (10) formed from a billet, each member (10) comprising a plurality of corrugated paperboard sheets (12) bonded together with an adhesive (14) and disposed between a core fiber layer (16, 18), each core fibre layer (16, 18) comprising at least one ply of a fibreboard sheet (19), a pair of caps (20, 22) of a solid fibreboard sheet bonded to respective side faces of the paperboard sheet (12) and to the respective edges (23) of the core fibre layers (16, 18). A method of manufacture is disclosed in which the billet is built up of corrugated paperboard sheets (12). 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. |
