Fortress Steel Framing Products in St. Louis, MO

Building a new deck? Make sure it stands the test of time by choosing the right framing system. Explore steel framing from Fortress Building Products in St. Louis, Missouri.

Fortress® Steel Deck Framing

Pressure-treated lumber may look great, but it’s prone to splintering, rotting, and warping. When installing a deck framing system, you don’t want to leave stability and safety to chance. Compared to a wood deck framing system, a steel deck and stair system is far more likely to withstand tough climates and not rot or warp over time. Fortress steel deck framing is well-known in the industry, and for good reason: the company makes study products.

Besides top-notch steel deck framing, Fortress also offers PVC decking, composite decking, steel railing framing, railing infills, steel fencing, aluminum fencing, composite fencing, cladding deck boards, deck fasteners, pergolas, post caps, LED lighting, and more.

Evolution™ Steel Deck Framing
