RDI offers many options and looks including vinyl, aluminum, composite, or even stainless steel cable rail in several different profiles.  Even if you don't want to replace your current railing, but just want to add some flair. RDI offers options in LED lighting.

If you are unsure of how each style may look on your deck, RDI offers their Railing Designer App as another solution.  You can build the deck of your dreams and see how it looks on your house all on the computer.
RDI railing is easy to install, low maintenance, and is long lasting so you can spend more of your time outdoors enjoying our shorter than desired summers here in Northern Michigan.
