Aluminum Water Resistant Decking

Craft-Bilt’s revolutionary aluminum locking seal and continuous gutter technology provides a gap-less floor for waterproof decking and roof covering with single layer construction. Aluminum decking is watertight underneath with no additional plywood or membranes required. The deck boards lock together under pressure to form a water resistant joint. In the unlikely event that any moisture gets past the pressure lock, there is an integral gutter in each deck board to carry it away.

Craft-Bilt aluminum decking is available in two colours, Desert Sand, and Grey. Desert Sand is the perfect match for our Desert Sand railing and it’s a nice light earth tone colour that goes with many home colour schemes. The Grey colour compliments any architectural decor, and for wood fans, it mimics the look of weathered cedar.

Decking Reviews


Residential Decking

Put on the last deck you’ll ever own! No more painting, staining, sealing, knot holes, splinters or decay. If you’ve been a homeowner for any amount of time, you’ll appreciate the true meaning of “maintenance-free” decking. Your deck will look new for years to come.

Commercial Decking

Convert almost any commercial rooftop into a useable area by using Craft-Bilt’s aluminum deck boards. Create an entertainment area, or a communal area for residents. Install decking material on sleepers and forget about it. Light-weight aluminum decking is ideal for this task since it will not add appreciable weight to the roof structure and it may help to extend the life of your existing commercial roof membrane.

Marine Decking

Our aluminum decking has non-skid finish. It is especially useful in a marine application. Protect yourself and your guests from slips and falls. Eliminate those yearly board replacements with Craft-Bilt maintenance-free aluminum decking. Our decking is found on:

  • Docks
  • Water Taxi Decks
  • Boat Decks
  • Boat Houses
  • Marinas


The Craft-Bilt decking system is a heavy gauge extruded aluminum product.

Extrusions are made by forcing heated aluminum under hundreds of tons of pressure through a special custom made die. The resulting shapes can be quite intricate and follow close tolerances. Different alloys and tempers are available depending on the strength required.

Aluminum decking components

Our decking is made from one of the strongest alloys available: 6005-T6. Testing by Trow Associates has shown that the 1″ x 6″ boards can sustain 1085 pounds per square foot on 24″ centers!


Before considering an aluminum deck board supplier, check the wall thickness of the product. The thinner the wall, the less they can sell it for.

Waterproof Decking Profile

Craft-Bilt’s Waterproof Aluminum Decking has passed the ASTM B117 salt fog spray test

The recognized body for aluminum paint finish standards is the American Architectural Manufacturers Association (AAMA).

Our Super-Durable exterior powder coat finish exceeds most of the specifications of the highest AAMA standard, 2605, and fully meets the AAMA 2604 quality standard. Compare these statistics to other aluminum deck board manufacturer’s who only paint to AAMA 2603. The AAMA 2605 specification includes chemical resistance, fading, gloss retention, 4000 hour salt spray and many other properties.


Craft-Bilt aluminum decking has also been tested against common household spills such as ketchup, mustard and beer with no change after four weeks of exposure. Although we only recommend detergent and water to clean the decking, we’ve further proven it’s durability by testing against harsher cleaners. Refer to the documents in the resources area for more information.

Waterproof Decking

The chemicals in pressure treated lumber can be corrosive towards aluminum. Un-treated lumber is typically all you need when using Craft-Bilt decking, since it controls the water no appreciable moisture will come into contact with the joists. Feel secure when installing Craft-Bilt aluminum decking knowing that it has passed the ASTM B117 salt fog spray test on the most corrosive ACQ pressure treatment formulation.

Our coating is formulated with a coarse additive to achieve high anti-slip properties. While everything is done to control these additives in the powder manufacturing and application processes, variations in colour can occur due to variables such as lighting, angle of viewing and the size, concentration and orientation of these coarse particles.


Aluminum boards are 1″ high by 6” wide. Standard lengths are 14′, 16′, 18′, 20′, 22′ and 24′ long. On large projects we can produce custom lengths to minimize your waste. Custom lengths are available up to 30′ long. (subject to change)
We have two standard colours: Desert Sand and Grey. Desert sand is a light beige that blends with many home exteriors, and it matches our sand railing colour. Grey goes with many outdoor landscapes, and it is the perfect choice with white or black railing. Custom colours are available for minimum sized jobs, but we do not recommend white deck boards since the reflection of the sun can be overwhelming.
In most circumstances they are waterproof. When the deck boards lock together, the joint is held under pressure by the fulcrum design of the lock. In the unlikely event that any moisture gets past the pressure lock, there is an integral gutter in each deck board to carry it away. Depending on local freeze/thaw conditions, melt water on the deck may overflow the hidden gulley if it contains ice – broom off melt water if desired. The boards will drain normally when the weather has settled to positive temperatures. Decking should not be used as the sole roofing solution over living space. There is no caulking in our deck joints, and no vinyl or rubber gasket, so you don’t have to worry about a seal that could deteriorate over time. Proper flashing from the house to the deck boards is important, as it would be with any product, refer to our decking installation guides.
Yes, our decking is truly non-skid. It will not be slippery like wood or other smooth surfaces. Some man-made materials may claim to have a non-slip pattern or textured finish, but only an embedded crumble provides true non-skid performance. It is the responsibility of the owner to maintain their deck in a safe condition, to remove any debris, ice or substance that could promote a slip.
Installation of our decking system is easy. If you are planning to install as a home owner, you should be familiar with power tools such as a power drill, mitre saw and skill saw. You will require special blades to cut the aluminum: carbide tip for non-ferrous metal. We have an “easy to follow” installation guide for aluminum decking. Installation basically involves cutting the boards to length, drilling clearance holes for the joists, and screwing the boards to the joists with our stainless steel screws.
When you think of metal, it is always cool to the touch. In fact, aluminum is used extensively as heat sinks for all sorts of consumer and industrial equipment. Craft-Bilt enlisted an independent test laboratory to do heat testing in direct sunlight. On a hot sunny day, our standard colour aluminum deck boards will not be warmer than any other decking material. Check out our YouTube channel for a product comparison.
Untreated lumber is typically all you need when using Craft-Bilt decking since it will not be exposed to the elements. The chemicals in pressure treated lumber can be corrosive towards unfinished aluminum, however Craft-Bilt has performed extensive salt spray testing with our deck boards on ACQ treated lumber, with no adverse effects. We used an independent testing agency who tested our deck boards on 24″ centres with outstanding results. The typical building code requirement for an outdoor deck is 100 pounds per square foot, our deck boards performed well in excess of that requirement.
Our sophisticated pre-treatment of the metal, and high quality powder coat formula will ensure a lifetime of service but as with any painted material, if you push hard enough, it can be scratched. The beauty of aluminum, is that it does not rust or decay in any way. It will still last a lifetime. Composites and vinyls may show scratches less, but they have a shelf life that can not be denied. More information can be found in our “New Deck Care & Feeding” document. If you do scratch the deck, Craft-Bilt can supply touch up paint or you can use any good quality outdoor paint made for walking surfaces colour matched locally. Consult the decking warranty before painting your boards.

Usually our desk boards are installed parallel to the house as you would expect, its suits most desk designs. The deck is watertight but as you can imagine it’s harder for the water to drain. Parallel installation is best suited to decks over walk-out basement or un-used space below. When it’s important for the space underneath to be dry, use perpendicular installation. Refer to our decking installation guides for more information.
