About Our Company

Born to Engineer

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 50 years. We are a premier, single-source manufacturer, providing total responsibility from design through installation of our structural skylights, skyroofs®, canopies, pool enclosures and entire building structures. Our unique, pre-engineered box-beam system can span areas in excess of 100 feet while providing a clean, finished appearance that is low maintenance, energy efficient and highly corrosion resistant.

Our structural aluminum framing, combined with Kalwall® translucent sandwich panels, forms a rugged, total building system. It is ideal for sustainable and resilient projects and can withstand hurricane-force winds and massive snow loads. Our structures provide perfect daylighting and open up a world of design and engineering possibilities to our customers. Levy our decades of engineering expertise to create a dramatic daylighting experience. Engineering daylight…it’s what we do.

Our Vision

Single-Source Responsibility

Building better daylighting solutions requires more than a high-quality product; it requires service that truly delivers.

By providing total responsibility not just for manufacturing, but for designing, engineering and installing our products, we are able to provide project efficiency and peace of mind. You get all the value of having a true partner serving as an integral part of your team.

We’re not only building better spaces for people, we’re delivering a better workflow for the AEC community.
