Composite Railing: The Smart, Elegant, Stress-Free Way to Frame Your View

In the world of composite deck railing, RDI Railing Composicore® resides in a class all its own. Backed by years of lab and field testing, our proprietary high-tech composite formula is the best choice when you want the look of painted wood rails or aluminum rails at a higher performing, longer-lasting value. 

Zero Wood Fiber Fill

While other composite railing brands use up to 60% uncapped wood fibers in their blend, our Composicore® railing formula relies on ultra-durable synthetic polymers rather than organic wood fibers to strengthen the railing to its core. This elimination of wood fibers guarantees our composite railing profiles will never soak up water nor retain it.

More Fun, Less Upkeep

RDI Railing composite deck railing guarantees you’ll enjoy spending more quality time on the patio and worry less about how to maintain it. Composicore rails are highly resistant to damage from mold and mildew, nor will they stain, crack, split or peel. Extensive third-party testing ensures the colors remain vivid and resist fading in the sun. Forget the paint brush, stain cloth, sanding block and enjoy the good times outside.

Real Long-Term Value

Of the many benefits RDI Railing composite profiles offer, the long-term value outweighs the cost of installing cheaper, lesser quality railings. Traditional wood railings eventually need repair and replacement every few years, costing you time and money. When comparing our Fusion composite railing to aluminum, no other railing offers our ground-breaking AlumiCast™ Technology that features the look of aluminum with the strength and value of Composicore. Innovative engineering and multiple patents ensure the beauty of every RDI Railing composite profile endures for years.

Multiple Price Points and Customization

Our diverse composite railing collections offer stylish options to fit every budget. Create a look all your own by choosing what type of finish you want — whether you’re seeking the look of finely grained, painted wood or matte black aluminum. Then select top rails and unique infill panels like cabling, aluminum balusters and other styles. Finesse your railing with lighting, gates, ADA handrails and more.

Check out the options:
