Abstract
A pole for supporting utility lines and the like is made of pultruded composites. In one embodiment, an interior lattice of composite members forms an elongated open-celled beam which is enclosed in a preferably composite outer skin. In another embodiment pole side panels are pultruded to define interlocking edges so they can be laid parallel to define an enclosure with the edges interfitting.
