Fortress Evolution Framing

After speaking with professional contractors and researching deck frame materials from around the world, Fortress Building Products realized that the North American deck market was missing a new key element: metal deck framing.

Relying solely on lumber for backyard projects, builders throughout the US are dependent upon availability, climate change, and rising costs. Fortress Building Products chose to get ahead of the issue and revolutionize the deck industry all-in-one with the Fortress Evolution Deck Framing system. A steel framing line that is affordable, easy to install, and incredibly tough.

Designed and engineered to look and install like standard wood, the Fortress Evolution line makes building a deck frame as clear as can be while the consistently uniform pieces eliminate second guesses.

Easy to Plan, Design, and Build

The Evolution system consists of 5 basic components to making assembly quick and straightforward!

  • Ledger- The part of a deck that attaches to a home or structure, Evolution's S-Ledger boasts an interlocking design with the Ledger Bracket that eliminates excessive fasteners and speeds up installation. The S-shaped piece sits securely on its brackets to provide a sturdy, safe deck connection that offers peace of mind.
  • Joists- Evolution Joists run perpendicular to the ledger board and create the outward run of your deck space. The steel joists of the Fortress Evolution system will hold their shape providing a perfectly flat deck surface that will not sag or warp over the life of your deck.
  • Beams- Running parallel to the attached home or structure, beams will create the width of your outdoor space. Fortress Evolution Beams have been engineered to achieve longer spans between supports than wood eliminating excessive support posts and obstructed views.
  • Posts- Fortress Evolution Steel Deck Posts provide the perfect solution to support your deck. The black powder-coated deck posts create a beautiful under-deck look and attach directly to concrete deck footings or piers.
  • Blocking- Blocking is additional support pieces that are attached to minimize movement and keep the frame firmly in place. Fortress Evolution Blocking is required when joist spans are greater than 8 feet long.
  • Brackets- Solid, tough connection points between different components of the Fortress Framing system such as post-to-pier or joist-to-beam attachments.

The straight, uniform steel framing pieces provide a perfectly flat surface without crowning, warping, or cracking over the entire lifespan your deck. Skip scanning lumber for knots, splintering, or rot! Instead, build once and enjoy forever with Fortress Evolution Steel Framing.

Durable and Resistant Material

The Fortress Evolution Steel Deck Framing line is made from noncombustible material and is resistant to fire damage. The coated steel framing pieces are also invulnerable to rotting, warping, splitting, and pesky insect damage for a deck you can truly relax on.

The Best In Fire Safety

Fortress Evolution Deck Framing has earned a Class A Fire Safety Rating from the National Fire Protecton Association. That's the most stringent fire safety rating available for building materials. In areas prone to wildfires, that's a game-changer in protecting your deck and promoting safety.

Fire safety ratings have also become an important consideration in building codes in many states and regions. You should make sure to consult local and regional building codes before starting a project. But Fortress Evolution Steel Framing's Class A rating will keep your project up to code in most areas, while creating a stronger and more durable frame.

Achieve Longer Spans and Grander Deck Designs

Evolution Steel Deck Framing has been engineered to provide greater spans between supports, resulting in fewer columns for less obstructed views. Create the deck design your backyard craves and build beyond your limitations with the modern strength of steel.

Curved edges and unique floor layouts are a breeze with the Fortress Evolution method. Customize your material list to your home's specific deck design and make your outdoor living space the new favorite room in the house.
