It’s imagination that fuels what we do at Structures Unlimited, but it’s our capabilities as engineers and our commitment to service that bring those possibilities to life. It’s been that way for over 40 years. We are a premier, single-source manufacturer, providing total responsibility from design through installation of our structural skylights, skyroofs, pool enclosures and canopies+walkways. Our unique, pre-engineered box beam system can span areas in excess of 100 feet, while providing a clean, finished appearance that is virtually maintenance-free, energy efficient and highly corrosion resistant. Our unique, structural system, combined with Kalwall® translucent sandwich panels, produced by our strategic partner Kalwall Corporation, forms a total building system that are ideal for LEED projects and can stand up to hurricane-force winds and massive snow loads. The balanced daylighting achieved by these structures opens up a world of design and engineering possibilities to architects and building designers, and our engineering expertise will assist you in creating a dramatic daylighting experience. Engineering Daylight…It’s what we do.
