Deck Railings, Gates & Features Gates, Hand Rails & Other There is a substantial variety of rail systems options available today. All of the major composite decking manufacturers offer a complimentary rail system. That said, there is no reason you can not use a Trex rail on a non Trex deck, or another brand on a Trex deck. They are all totally interchangeable with the style, colors, and cost being the main decider. We are also very partial to aluminum (Sapa, Trex, and Hansen brand) railing. These come in several color choices with either pickets, glass, or cable infill. The aluminum, in general, is lighter looking, and more cost-effective than the composite rails. If you like wood, we can match or do any style.
