Williamsburg Fiberglass Pergola

Structureworks fiberglass is used to create the strongest pre-engineered and wind load rated fiberglass pergola kits available. Designed to meet the most demanding requirements of any residential or commercial environment, our fiberglass pergolas offer incredible strength along with numerous design options and are finished using our proprietary ColorLast paint process.

Our Williamsburg fiberglass pergola kits feature full size 2″ x 8″ double beams that support 2″ x 8″ rafters, which are spaced no further apart than 24″ on center. Shade is provided by 1 3/4″ square stringers that are spaced every 12″ on center. Stainless steel hardware and detailed installation instructions are included with each pre-fabricated kit we make. Add a pergola canopy, lighting, curtains, heaters or a fan to create the outdoor retreat of your dreams.

Our structural fiberglass components are hand fabricated, lightweight and offer a low maintenance alternative to traditional pergola kit materials. Limited only by your imagination, Structureworks can create a classic pergola design or modern shade structure to perfectly fit your architectural style. Let us know what pergola design ideas you have, and we will work with you to design an easy to assemble fiberglass pergola kit that comes with everything you need for a simple installation. All fiberglass pergolas utilize our exclusive ColorLast finishing process that gives you a lasting finish and the freedom to coordinate your pergola with your outdoor environment.

A versatile fiberglass pergola kit from Structureworks provides a beautiful focal point with just the right amount of shade and privacy for your outdoor living design.
