CC Series

Built to Adapt

Widths: 32', 42', 52' & 62'

Calhoun's Compression Coupler structure combines a coupler and gusset to allow for a longer transfer of pressure over the connecting cords. This design allows us to achieve greater design capacity over the competitor's flat plate gusset design that transfers pressure to the end of the tube only.

HT Series

Reach Greater Heights

Widths: 50', 60', 65', 72' & 82'

Calhoun's High Top series uses the same unique compression couple design as the CC Series, but uses larger top and bottom cords and a deeper truss depth. The HT Series comes standard with our individual Keder Panel System.

Ideal for customers looking for extra interior height. The extra height and free span space makes unloading large trucks easy and worry free. The HT design also makes it a "tank" in heavy snow load areas.

Superior Engineering

Calhoun Super Structure uses cutting edge technology when it comes to engineering your fabric tension building to your exact site loads, use and application. Being one of the only names in the industry to utilize 3D Finite Element Nonlinear Analysis, we can give detailed points of pressure or stresses on each specific area of your building. Knowing that each building, location and application is unique, we use only the most precise and premier technology currently available. Our team of highly trained Engineers, Designers and Detailers are what sets Calhoun Super Structure apart from the competition. They have made it their personal mission to ensure that your building is engineered to be the strongest, most reliable structure on the market.

Engineering Details

The engineering status quo in the industry involves a linear elastic portal frame analysis wherein the load is only approximated. When our competitors implement this type of analysis during the engineering phase, they are simply using assumptions. This 'best guess' approach means that the amount of force applied to each point of the structure cannot be accurately predicted and could prove disastrous, leading to catastrophic failures of the structure.

Calhoun is always one step ahead of its competitors. We go the extra mile to ensure that every structure installed is engineered to the highest possible standards, leaving our customers with a safe and reliable building.

Calhoun's 3D Finite Element Nonlinear Analysis process completed for each project makes our structures not only safe, strong, and reliable, but also environmentally sustainable and economical. With over two decades spent perfecting this engineering, Calhoun buildings far exceed the status quo in the industry. It's all in the details - and we've got you covered.

Super Shield

We offer an extra layer of protection for your structure when you are storing corrosive materials, like fertilizer or salt. Super Shield is our rubberized spray coating, designed to add an extra layer on top of the hot dip galvanized structure to provide superior protection.

Super Shield lengthens the life expectancy of your hot dip galvanized trusses and base plates by guarding against deterioration and corrosion. The rubberized spray coating can be applied to your concrete and block wall foundation to create a moisture barrier protection layer, and to seal cracks.
