Abstract

An elongate structural member has a longitudinal axis and is comprised of a plurality of elongate panels having lateral edges, the panels being arranged to form an elongate central cavity with lateral edges of adjacent panels being fixediy joined together. The elongate panels are each comprised of a plurality of wood particles intermixed with a suitable binder and compressed to form a densified product. A rigid foam material is provided filling at least a portion of the elongate central cavity for reinforcing the elongate structure, the rigid foam material also being bonded to the inwardly facing surfaces to further reinforce the elongate structure.
