Fiberglass Balustrades

RoyalCast™ Composite Fiberglass Balustrades

Royal Corinthian manufactures a paint-grade composite fiberglass balustrade system in every style as our RoyalStone™ Balustrades. This system comes with all of the structural and robust features except varies slightly in composition. As with all our balustrades, RoyalCast™ fiberglass systems exceed building codes for structural balustrades used in residential and commercial applications. These balustrades offer the greatest advantage over our other systems when a paint-grade, low maintenance, structural system is desired that can span up to 20’ without interruption.

Material Composition and Process

RoyalCast™ balustrades are comprised of the same material as our cast fiberglass columns. The product is rotational cast using a slurry consisting of filler, polyester resin, and fiberglass chop strand, which results in a hollow but robust balustrade system. A typical system will weigh from 20 to 100 lbs. per lineal foot but can be decreased to half the weight with alternative lightweight fillers. In instances where ASTM E 84 Class A flame spread and smoke density is required, which is unnecessary for outdoor use, we add ATH or Alumina Trihydrate to the mix. Just like our RoyalCast™ columns, the end result is a very robust product that is grayish in color that will require some additional sanding, priming, and final paint finish.

Product Offering

Comprised of balusters, rails, posts and post caps, finials, and hardware, our RoyalCast™ fiberglass balustrade combinations are virtually endless: We have over 50 standard balusters, 20 different rails, 26 different newel posts, 18 post caps, and an assortment of decorative finials and trims. Keep in mind that all of our standard posts and balusters can be made shorter and taller without additional charge which makes for even more possibilities. Our standard balusters range from 1-1/2 to 7” in width and up to 40” in height and our rails from 4-1/4” to 10”. We can combine our various products to form balustrades that even meet pool fence height requirements. Even if all of these variations don’t meet your aesthetic or functional requirements, our in-house mold making department makes custom balustrades relatively inexpensive. The majority of our standard products were once custom so we are always ready and willing to match a style that you like or replicate a historic system for restoration.
