A hollow light weight pole like structure suitable for use as a utility pole, column or log building member is made of a plurality of wood strips glued edge to edge forming a hollow interior core, with at least one layer of high strength veneer material glued to the exterior of the wood strips with the veneer grain running parallel to the length. The layer of veneer increases the strength, distributes bending stresses uniformly, provides greater decay resistance than ordinary glued hollow poles, and increases the service life. The veneer can be made in several layers forming a continuous overwrap without longitudinally extending gaps that expose the interior wood strips to weather or splitting.

A hollow elongated member comprising a plurality of elongated wood strips having generally trapezoidal cross sections with outer surfaces and side edge surfaces formed at an angle relative to each other so that when the plurality of strips are placed side to side, a hollow core is formed with a substantially continuous outer surface; an adhesive for holding the wood strips in an assembled condition forming the hollow core; and at least one substantially continuous layer of high strength veneer material on the exterior of the formed hollow core extending throughout the length and periphery of the core to provide a high strength outer layer intimately, permanently secured on the core.
