Making history

55+ years of engineering daylight


Twelve years after they revolutionized the natural daylighting industry, Kalwall’s® translucent sandwich panels found a perfect complement in Structures Unlimited. We incorporated in 1968 as a strategic partner to Kalwall, cladding our aluminum box-beam superstructures with Kalwall panels, creating brilliant settings that utilize diffuse natural daylight. Our first applications were daylit residential and commercial pool enclosures. In the 1970s, we expanded our product line with the introduction of monumental translucent skyroofs® and again in the 2000s with toplit walkways and canopies.

From swimming pools and natatoriums to gyms, libraries, museums and classrooms, Structures Unlimited is the premier single-source manufacturer of structural daylit systems. 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.

We pride ourselves on our customer service and commitment to see a project through from start to completion. We are vertically integrated. We design, manufacture, ship the product on our own trucks and install with our own factory-trained crews when applicable. Single-source responsibility provides our customers with a high level of comfort and satisfaction, and the list of projects recognized by both the building industry and the architectural community continues to grow.
