Fortress® set out to prove that cost-effective decking could still deliver the strength, usability and beauty of its premium cousins. Well, we did that and more.
Our new Infinity® I‑Series decking is 40% lighter, while keeping the same stiffness and mechanical properties. This revolutionary design uses the historically proven I-beam shape, which is uniquely capable of handling heavy loads.
