Aluminum Substructure

Sprung structures aluminum substructure outperforms steel at every turn. Sprung uses an extruded, military-grade aluminum substructure that provides superior performance, durability, and longevity. It also has an indefinite life expectancy and comes with a 50-year pro-rata guarantee. Our one-piece extruded aluminum I-beam with an integrated membrane retainer channel is engineered to endure extreme weather and environmental conditions.

Advantages of Aluminum Over Steel

Rust proof

Essential when integrated with an architectural membrane exterior.


Aluminum can be extruded into virtually any shape. Connections are bolted, not welded.

Environmentally Friendly

Aluminum is 100 percent recyclable, with no generational loss of quality.


Ideal for shipping to remote locations and easier to erect.


With an almost indefinite life expectancy, aluminum actually gets stronger with age.

Aluminum Is Recyclable or Reusable

Nearly 75 percent of all aluminum ever produced is still in use today.

Extruded Membrane Retainer

Our one-piece extruded aluminum I-beam, complete with membrane retainer, eliminates the need for a separate bolt on the membrane retainer system, as typically found on fabric buildings that use a steel substructure.
