A fiberglass ladder comprising a pair of rails and a plurality of rungs interposed at selected intervals. Each rung and each rail has a continuous layer of fiberglass filaments extending parallel to its respective length. At the intersection of the rails with the rungs, the filaments bend with a portion of the filaments in the rung extendingin one direction along the rail, and a portion of the filaments in the rung extending in the other direction along the rail. The ladder is cast in a mold in a solid integral piece. Woven fiberglass is placed in the channels of the mold over a coating of resin. The fiberglass filaments are placed over the fabric in the bottoms of the channels. The channels are then filled wth a rigid plastic foam and the ladder is allowed to cure.
