Royal Corinthian

Composite Balustrade Systems

Exterior Balustrade Systems

Royal Corinthian manufactures 3 structural balustrade systems made from composite materials that will last for generations. Our balustrades, which are comprised of balusters or spindles, top/bottom rails, newel posts and caps, decorative finials, and installation hardware, are available in RoyalCast™ composite fiberglass, RoyalStone™ polymer stone, and RoyalThane high-density polyurethane. Each of our systems has been independently tested by engineering firms and exceeds commercial and residential building code requirements for a structural balustrade.

All of our composite balustrade systems are lightweight systems when compared to natural stone, but some are significantly lighter than others. We are the only manufacturer that offers all 3 materials in the same styles, so the same project can use our RoyalStone balustrades on the front porch and our lightweight polyurethane system on a rooftop that has weight restrictions, making them ideal commercial balustrade systems. If you want to know more about each of the 3 materials, look at the comparison chart below. If you already know which product you are looking for, click on the appropriate product.
