Aluminum Decking

The Next Generation of Decking

NextDeck® is a revolutionary decking product that offers unsurpassed durability and longevity. Specifically designed to replace other high-maintenance decking products, NextDeck® delivers a truly maintenance-free choice.

Why struggle with scrapping, staining, sealing or painting wood, composite or pvc decking? NextDeck® gives homeowners the freedom to enjoy their outdoor living space and activities, rather than spending countless hours and money on deck maintenance and repairs. Designed for the life of your deck, NextDeck® aluminum decking is fireproof, pest resistant and will not rust, rot, sag, splinter, warp or crack in freezing temperatures.

NextDeck’s® SuperDurable™ powder coat finish was developed to provide an extremely strong, UV stable surface finish. Due to excellent color retention characteristics, SuperDurable™ powder coat ensures there are no before and after color changes or fading typically experienced with traditional composite deck products. NextDeck’s® surface is also slip-resistant for added safety and security.

Engineered with the homeowner in mind, NextDeck’s® patent-pending hidden fastening system correctly spaces the decking boards for a consistent gap and easy installation. Aircraft grade aluminum extrusion provides very high strength to weight capability and permits wider joist spans. Simple to install and simple to maintain… NextDeck® is simply the ideal choice for your next deck!

NextDeck® offers the same great features as LockDry®, but it does not create a waterproof area below the deck.

NextDeck® is available in 2 standard colors and Dakota Oak wood grain.

1: How do I get product and pricing information.
Directly from us. We sell and ship all products direct to keep cost minimal. Please fill out our contact form for free samples, literature, and pricing.
2: What information do I need to send for a detailed quote?
We like to get a faxed or emailed drawing from the customer showing the outside dimensions of the deck. This helps eliminate any confusion and allows us to lay out the decking for minimal to no waste. Please visit the Downloads link to download a design sheet to draw your deck on. Please visit our Contact Page for contact information.
3: What lengths are available?
LockDry decking is available in 12’-2" – 32’-2" lengths in 2’ increments. It is also available up to 40’ if needed. NextDeck is available in 12’ – 16’ – 20’ – 24’ lengths. Wood grain colors are only available up to 20’ long.
4: How is the decking cut and what tools will I need?
Standard woodworking and power tools are all that you need. Most orders only require an electric drill with assorted drills and bits, tape measure, pencil, & a hacksaw. For cutting the decking, a blade for non-ferrous materials must be used. Example: DeWalt® DW3217 – 10" 80T Non-Ferrous Metal Cutting Blade or equivalent. DeWalt® DW3229 – 12" 80T Non-Ferrous Metal Cutting Blade or equivalent. Non-ferrous cutting blades can generally be purchased at local hardware or welding supply stores. We also stock 7 1/4", 10" & 12" blades.

7: Can LockDry be installed directly on joists or plywood?
Yes. The decking can be installed on any standard sub-structure providing there is adequate pitch for drainage. It is recommended to remove any existing decking to have a flat surface to fasten to.
8: What are the main requirements for my deck framing for LockDry® decking?

Proper slope: The deck framing needs to be sloped in the direction that water needs to drain.

The decking also needs to run in the same direction.

Flatness: The framing needs to be flat and true with no major dips, rises, or waves.

9: How much does LockDry & Nextdeck decking weigh?
LockDry is 2 lb. per square foot. About 1/2 the weight of wood and much stronger!
10: How hot does the surface get in the sun?

LockDry & Nextdeck decking stays cooler compared to wood or concrete. Our powder-coat finish reflects heat combined with the heat dissipation properties of aluminum. It is recommended to have adequate air flow under the decking for maximum heat dissipation.

11: How well does it hold up in very hot and cold climates?
LockDry® & Nextdeck decking are one of the most durable decking products available. Because of the aluminum construction, it is able to withstand extreme heat and cold. Aluminum has a working temperature of -400 to 400 degrees F. They are completely fire proof and has a melting point over 1200 degrees. They will not freeze and crack because aluminum does not absorb water. They also have very low expansion and contraction characteristics because of the lack of water absorption.
12: What other products are made out of aluminum?
Window frames, doors, roofing, framing, and siding are just a few. Aluminum products are also widely used in the automotive business. Car and truck engines, frames, and body panels. Semi-truck trailers are also made out of aluminum for the high strength to weight ratio and corrosion resistance for the northern climates.
13: How Durable is the Powder Coat Finish?
Powder Coat is one of the strongest and most durable paint finishes available. Our finishes surpass requirments by the American Architectural Manufacturers Association AAMA-2604 specifications. Typical test requirements are 5 years of vary minor color change or fade, 3000 hours of salt fog testing and humidity tests.
14: Can I Install a Gutter at the End of the LockDry Deck?
Yes, a typical gutter used for a roof can be used.
15: How do you handle uneven deck widths?
The last board can be ripped lengthwise to fit uneven widths. The edge trim profile can be installed to cover the exposed edge.
16: How long will it take to receive an order.
We typically ship in stock products within 2 days. If we have to manufacture, lead time is usually 3-6 weeks. Shipping times vary. Most shipments take 1-5 business days.
