Abstract
A pile is comprised of a pipe, i.e., a hollow tube or hollow cylinder, with a coextensive internal reinforcement comprised of a plurality of intersecting walls. The pile is comprised of a blend of a thermoplastic and 20 to 50% (pbw) pelletized chopped strand glass fibers. The outer surface includes a co-extruded cap stock that is relatively smooth and exhibits a relatively low coefficient of friction. The internal structures exhibit roughness, bumpiness and a relatively high coefficient of friction for an extruded plastic. A groove may be formed in the pile adjacent to an end for resistance to uplift.
