Everything You Need to Know About Aluminum Decking
If you’re considering aluminum decking for your home, you probably have questions. Does it get too hot? Will it last? Is it worth the investment? We’ve spent years helping homeowners make this decision, and we’re here to give you straight answers based on real-world performance and testing.
Does Aluminum Decking Get Hot in the Sun?
Here’s the thing everyone worries about: “Won’t metal burn my feet?”
Actually, no. Aluminum heats up differently than you might think. Yes, it warms in direct sunlight, but it also releases that heat quickly because aluminum is highly conductive. It’s the same reason your car’s radiator and computer heat sinks are made from aluminum—it moves heat away efficiently.
Our test shows that Craft-Bilt aluminum decking reaches similar or even lower temperatures than composite and vinyl boards on hot summer days. So if you’re building a deck in full sun, aluminum is actually a comfortable choice.
Will Aluminum Decking Rust or Corrode?
Short answer: Aluminum can’t rust. Rust only happens to iron-based metals, and aluminum doesn’t contain iron.
We take things further by using 6005-T6 aluminum alloys with a powder-coated finish and advanced pre-treatment. This combination protects against moisture, salt spray, and oxidation—even in harsh environments. If you live near water or in a humid climate where other materials break down fast, aluminum holds up beautifully.
How Long Will My Aluminum Deck Last?
This is where aluminum really shines. A properly installed aluminum deck can last 30 to 50 years or more. That’s not marketing talk; it’s based on the material’s inherent durability.
Craft-Bilt aluminum decking won’t rot, warp, twist, or splinter. It doesn’t absorb water, which is the main culprit behind most deck failures. We back our product with a limited lifetime warranty because we know it’s built to last. For many homeowners, this is the last deck they’ll ever need to install.
Is Aluminum Decking Slippery When Wet?
Safety matters, especially around pools or during rainy weather. Our aluminum decking features a textured, slip-resistant surface specifically designed for wet conditions. The profile gives you secure footing even when it’s soaked.
Whether you’re stepping out after a swim or walking across your deck in the rain, the non-skid surface maintains grip and stability.
What Kind of Maintenance Does Aluminum Decking Need?
This is one of the best parts: barely any.
You don’t need to stain it. You don’t need to seal it. You don’t need to paint it or treat it for mold. Maintenance comes down to:
- Rinsing it off occasionally
- Washing with mild soap and water when needed
- A quick visual check now and then
That’s it. While your neighbours are spending weekends refinishing their wood decks or scrubbing composite boards, you’ll be relaxing on yours.
Is Aluminum Decking More Expensive?
Upfront? Yes, aluminum costs more than pressure-treated wood and many composite options.
But here’s what that doesn’t account for: aluminum never needs replacing, refinishing, or major repairs. Wood decks often need replacement every 10 to 15 years. Composite can fade, stain, and require treatment for mold. Aluminum just keeps going.
When you factor in decades of use with virtually zero maintenance costs, aluminum often becomes the most economical choice. Think of it as buying quality once instead of replacing cheap materials repeatedly. Check out our Aluminum Decking Cost Calculator, and don’t forget the ask about our promotions.
Is Aluminum Decking Noisy to Walk On?
Modern aluminum decking systems are designed for quiet performance. When installed correctly following our guidelines, Craft-Bilt’s watertight design provides a solid, quiet walking surface. Proper fastening is key—follow the installation instructions and you won’t have noise issues.
Is Aluminum Decking Fire-Resistant?
Absolutely. Aluminum is non-combustible, meaning it won’t catch fire or help flames spread. If you live in an area with wildfire risk or strict fire safety codes, aluminum decking gives you real peace of mind. It’s one of the safest decking materials you can choose for fire-prone regions.
Can Insects Damage Aluminum Decking?
Nope. Termites, carpenter ants, and other wood-destroying insects can’t touch aluminum. This eliminates one of the most expensive and frustrating problems wood deck owners face, and it’s another reason aluminum lasts so long.
What Colours and Finishes Are Available?
We offer a couple of durable powder-coated colours designed to match different home styles. The finish resists fading and maintains its appearance over time without any touch-ups. Unlike wood that needs periodic staining or painting to keep its look, aluminum keeps its colour year after year.
Why Homeowners Choose Aluminum
At the end of the day, people choose aluminum decking because they want something that works. They’re tired of maintaining wood decks or disappointed by composite materials that didn’t live up to the hype.
Aluminum gives you longevity, minimal maintenance, corrosion resistance, slip resistance, and comfortable heat performance all in one package. Whether you’re building a backyard deck, a waterfront retreat, or a rooftop living space, aluminum delivers durability that wood and composite simply can’t match.
Craft-Bilt manufactures aluminum decking right here in Canada. Our watertight design is backed by decades of experience in the industry. If you want the last deck you’ll ever install, aluminum is the smart choice.
