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 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. 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.
