Royal Corinthian manufactures architectural columns, balustrades, entablatures/cornices, pergolas, domes, fireplace surrounds, exterior shutters, faux wood beams, and virtually any architectural element from fiberglass, PVC, synthetic stone, GFRC, lightweight cast stone, and polyurethane. This rotunda pergola encompasses three of our products: columns, domes (concave and convex), and an entablature, all made from lightweight fiberglass, which can withstand hurricane-rated winds. While these products are available separately, this rotunda pergola is available as a kit, which includes all the necessary hardware to install in less than a day. This pergola was paint-grade but it can come in an assortment of gel-coat finishes or with a stone finish in a variety of colors and textures. All Royal Corinthian products are affordable, made quickly, installed easily, and are guaranteed to last for generations.
