Aluminum decking actually stays cool under foot even in hot conditions, and is also fire resistant. It is lightweight but able to support heavy loads, and is all but indestructible.

That said, there is no denying that aluminum decking is one of the more expensive options on the market, and it isn’t easy to install.

So how do you know if aluminum decking is right for you?

In this comprehensive guide, we will take you through the pros and cons of aluminum decking, the associated costs, installation, and maintenance processes, and also the best brands to look at if you do decide to invest in this innovative alternative deck flooring.

Quick Links

Already decided that you are a fan of aluminum decking and what to jump straight to the best brands? Here are our top picks.

What Is Aluminum Decking

Well, it is pretty much what it says on the tin. Aluminum decking is outdoor deck flooring planks made from aluminum. But what sets this decking apart is that it will pretty much last indefinitely, even in the toughest weather conditions, which can make short work of wood or composite decking options.

What Is Aluminum Decking

The material itself is both lightweight and strong. Most standard decks can hold weights of between 225 and 260 per square foot with ease.

The planks are also generally coated with fade-resistant and durable materials, such as polyurea elastomer, that help the deck retain its look. These finishes will also reduce slipping hazards and dampen any metallic noises.

While standard aluminum decks won’t be damaged by water, it is also possible to get watertight aluminum decking. Watertight aluminum decking will keep whatever is underneath it dry. This makes it a great option for second-story or rooftop decks that also create a patio area underneath.

There are a variety of different plank designs available, including options that look like hardwood planks. Planks are generally six inches wide and come in lengths between 12 and 20 inches, but exact details depend on the manufacturer.

Aluminum Decking Pros

Longevity

Aluminum decking, as long as it has been anodized or coated, will last longer and look better in outdoor conditions than other popular decking materials, including wood. In fact, many manufacturers offer limited lifetime guarantees on their products, so you can be confident that your deck will last as long as you choose to stay in your home.

Low Maintenance

Aluminum decks are extremely easy to maintain, as they won’t splinter, warp, crack, or otherwise become deformed, unlike most decks made from natural materials. While you will probably want to repaint your boards regularly to keep them looking fresh, they won’t be damaged by UV rays. Mold and mildew are also a non-issue.

Cleaning can be done easily with a hose and a soft broom. Low-level pressure washing is also an option, though this is not recommended by all manufacturers as it can compromise the product’s coating. Always read specific manufacturer’s instructions for how to clean and care for your deck so that you do not inadvertently void your warranty.

Strength And Durability

While aluminum planks are light, they are incredibly strong. They can hold heavy weights in excess of 200 pounds per square foot, which is great if you plan to keep your grill on the deck. These planks are also scratch-resistant, so they should upld up well, even if under heavy traffic.

Safe

Aluminum decks are fire-resistant. They are also strong so they are unlikely to buckle under heavy weights.

Environmentally-Friendly

If you do decide to remove your aluminum decking in the future, they are recyclable, which means that they won’t be sitting in landfills for years to come. Many decks are also partially made from recycled materials.

Aluminum Decking Cons

Expense

Aluminum decking will cost more than a wood deck, though how much more depends on the species of wood you are comparing costs with. Aluminum can cost up to three times as much as popular composite decking materials such as PVC.

Installation

While aluminum decking is not necessarily difficult to install, it does require specific tools, which may therefore require the services of a professional. In particular, the planks are difficult to cut and will require a carbide-tipped non-ferrous saw blade. This is not a tool that most DIYers have lying around.

Style

While many manufacturers will boast that they have a variety of aluminum deck floor styles, including options that look like hardwood, the reality is that you have much fewer style and color options that you would with wood or composite decks.

Sound And Temperature

While manufacturers can make aluminum decking that looks like hardwood, it won’t feel like hardwood underfoot. However, aluminum decks tend to produce a relatively loud and hollow sound underfoot, which is a dead giveaway that the material is aluminum and not hardwood. Aluminum decks tend to stay cool even in hot temperatures, which can be an advantage.

Slippage

While most aluminum decks are treated with materials to make them anti-slip for human use, they can still be a slippery surface for pets.

Also if it gets icy, there is not much that will make the deck feel like anything but an ice rink.

Aluminum Deck Costs & Installation

There is no denying that aluminum decking is an expensive flooring solution, as it costs quite a bit more than other decking options.

Aluminum Deck Costs & Installation

As is always the case, exact pricing depends on the quality and the brand that you choose, but you should be expecting to pay between $15 and $50 per square foot for materials, with average costs of between $25 and $35. This high cost is in part because most materials will need to be obtained from the manufacturer, as local DIY stores are unlikely to carry the bits and pieces that you need, unlike with other decking materials.

To put that in context, the average homeowner spends on $6 to $8 per square foot for wood decking depending on the type of wood. Composite decking alternatives also cost less, starting at around $5 per square foot.

Also consider that you are unlikely to be able to install the decking yourself. While the process is not vastly different from the process of installing a wood deck, special tools are required to cut the aluminum materials. For example, to cut the planks you will need a carbide-tipped non-ferrous saw blade.

Considering the cost of these tools and the expertise required, it tends to be cheaper to enlist the services of a professional. For this, you should expect to pay around $5 to $7 per square foot.

What does all that mean? Expect to pay upwards of $10,000 for a typical 300 square foot aluminum deck.

Aluminum Deck Maintenance

One of the advantages of aluminum decking is that it is easy to care for and maintain.

Quality aluminum decking comes pre-coated and should not have to be resealed. It should be impervious to rust, mold, and mildew, as well as insects and pests. You may wish to repaint every few years to give the deck a fresh lease on life.

Aluminum Deck Maintenance

The decking is easy to wash with mild soap and a soft brush and can then be rinsed off with a hose.

While pressure washing is also a viable alternative, not all manufacturers recommend using a pressure washer, as it can compromise the finish coating. If you do choose to power wash, do so at a low pressure no more than 1,300 psi.

It is important to follow the manufacturer’s cleaning instructions, as most aluminum decks will come with a limited lifetime guarantee, which means that it is guaranteed for as long as it is in the hands of the original purchaser. Naturally, you wouldn’t want to do anything to void this coverage.

Most manufacturers suggest checking your deck over twice a year for loose screws or damaged areas so that repairs can be made before becoming larger problems.

FAQs

Does Aluminum Decking Scratch Easily?

Aluminum decking is highly scratch-resistant thanks to the powder coat that protects the aluminum. Of course, no material is 100% scratch resistant, and with enough use or a heavy and sharp enough instrument, it will scratch. But the coat–and any paint or other finish that you choose to apply–can also be touched up.

One thing to be wary of is snow removal. Always use a broom rather than a shovel to avoid damaging the deck.

Is Aluminum Decking Hot?

No, aluminum decking actually stays cool in hot weather conditions, and is even fire-resistant. This is because aluminum has more electrons than alternative decking materials, such as wood and plastic. This means that it distributes heat throughout the material in a stable way that prevents any one area from overheating.

Is Aluminum Decking Noisy?

While quality aluminum decking will have a casting applied to help dampen noise, aluminum decking can be noisy. Heavy footfalls will ring out, and you may also find that the deck produces noise when it rains.

What Is The Best Low Maintenance Deck Material?

Aluminum is the best low-maintenance deck material. It is not adversely affected by the elements, so it will not buckle or splinter like other materials. It is also impervious to insect attack and won’t develop mold or mildew.

Aluminum decking is easy to clean, as it only requires soap and a soft brush and then rinsing with water.

What Decking Material Lasts The Longest?

Aluminum decking will potentially last forever. It will not be damaged or destabilized by outdoor weather conditions, and while you will want to repaint it to freshen up its appearance, it should maintain its structural integrity potentially forever.

Many aluminum decking brands come with a limited lifetime guarantee, so you can be confident that your deck will last as long as you choose to stay in your home.

How Do You Clean Aluminum Decking?

The best way to clean aluminum decking is to wash it down with a mild soap, scrubbing at any grimy parts with a soft brush. The soap can then be rinsed away with a hose.

You can also clean your deck with a pressure washer if you have one. However, many manufacturers don’t recommend doing this regularly, as a powerful pressure washer may compromise protective coating.

The Verdict

Aluminum decking is changing the market when it comes to outdoor decking. No longer are you forced to choose between natural wood decking, which is difficult to maintain and often buckles under the elements, or composite alternatives such as PVC, which tend to look and feel cheap.

Aluminum decking is an extremely durable alternative that won’t be affected by weather conditions or other outdoor threats such as insects and mold. In fact, it is so durable that it can potentially last forever.

While it is an attractive and safe decking option, it is also more expensive than the alternatives. However, part of this expense can be offset by the fact that you should never need to replace the deck.

Don’t be surprised if you see aluminum decking becoming one of the most popular decking options on the market over the next few years.
