Abstract: An entire structure utilizing fiber reinforced plastic (FRP) pultruded structural shapes is provided for use in decks, docks, and boardwalks. This deck system for building decking, docks, boardwalks, walkways, gazebos, hot tub decks and spas can be built either to and extending from the exterior side of residential or commercial structures or as an independent, freestanding structure. The invention is assembled from FRP pultruded components comprising several systems which include a weight bearing support system, flooring system, safety system, roofing system, and decorative system. Components of the invention including but not limited to vertical support posts, horizontal decking, railing, stairs, gates, doors, frames and supporting members will be manufactured from FRP pultrusion structural shapes and composite sections using corrosion resistant hardware and adhesives.
