Fortis Residential Aluminum Decking

Low-Maintenance Aluminum Deck Board With A Hidden Fastener System

Fortis® Residential Aluminum Decking: Low-Maintenance, High-Traffic Aluminum Decking

Fortis is a premium aluminum deck board designed for outdoor living spaces that don’t require waterproofing underneath. It installs much like traditional wood planks but delivers significantly more value—offering long-lasting durability with virtually no maintenance. Homeowners choose Fortis for its ease of installation, resistance to pests and extreme weather, and exceptional lifespan. With a Class “A” fire rating, Fortis also provides peace of mind in areas prone to wildfires or high heat.

The hidden fastener system gives Fortis a clean, seamless appearance, while its non-skid surface remains cooler to the touch than wood or composite decking—making it a safer, more comfortable choice for families and pets.

Fortis is made from approximately 50% recycled aluminum, making it an eco-friendly option for sustainable building. Each 8-inch-wide board is available in lengths up to 24 feet and can be custom-cut to match your project’s needs—saving you time, labor, and material waste.

Low Maintenance

Especially when compared to traditional deck boards, the marine-grade aluminum and powder coated finish of your Fortis residential aluminum decking never need to be stained, painted, or sealed. Fortis requires no upkeep outside of periodic cleaning with soap and water.

Heat Regulating

Heat-Regulating: Stays cooler to the touch than traditional decking materials: aluminum rapidly dissipates heat, which keeps AridDek’s surface cooler to the touch than commonly-used decking surfaces.

Eco-Friendly

Eco-Friendly: Fortis is 100% recyclable, and is made from up to 50% recycled scrap metal. While most building materials will eventually end up in a landfill one day, Fortis Aluminum Decking can be separated and recycled again.
