A method of forming an elongated composite element includes providing an elongated tubular member and establishing a plurality of holes through an outer wall of the elongated tubular member. A polymeric resin is provided that comprises a curable material that, when uncured, comprises a fluid material and that, when cured, comprises a substantially rigid material. The uncured polymeric resin is extruded along the elongated tubular member, whereby the polymeric resin flows at least partially through the holes and is disposed within the inner cavity and at an outer surface of the outer wall of the elongated tubular member. The polymeric resin is cured to form the composite element whereby the cured polymeric resin limits flexing of the at least one elongated tubular member and the elongated composite element.
