Composite vs Aluminum Deck Railing
A fair comparison of composite vs aluminum railing involves weighing several factors and preferences. Both materials have their own sets of strengths and weaknesses. For instance, aluminum railing is a bit more durable, and composites are a bit more economical in terms of costs and provide a more traditional (less contemporary) style.
Those are just the tip of the iceberg when it comes to examining the pros and cons of these two railing materials. Learn more about the differences between composite vs aluminum railing, and how to pick the right railing for your project.
The average material cost of aluminum railing is around $30-$45 per linear foot. However, this price can increase considerably when accounting for installation fees. There are many factors that can dictate final installed cost. The complexity of the install, DIY vs. hiring a contractor, and the materials chosen can all drive significant changes to installation costs. Fortunately, due to the low maintenance aluminum railing requires, the lifetime cost is often less than other materials, such as wood.
The average cost of composite railing is around $28-42 per linear foot. The same factors that can drive variances in installation costs for aluminum railing also affect composites. Composites are also available in a much wider range of quality than aluminum materials, which can further affect pricing. Composite railing is also lower maintenance, but manufacturer warranties for composites are, at times, shorter than some aluminum products. Both can offer lower lifetime costs than products that require intense maintenance.
Maintenance and Upkeep
Aluminum is typically given a protective coating to prevent rusting (typically, powder coating), which makes it fundamentally waterproof. It’s also highly tolerant to drastic changes in temperature. However, performing basic levels of upkeep is still necessary to keep aluminum railing looking its best.
Rails will need to be kept free of debris and occasionally cleaned of environmental contaminants using mild soaps. However, powder coated surfaces can interact with certain cleaning agents. It’s important to follow manufacturers’ guidelines when selecting cleaning products.
Aluminum railing can also be damaged by using abrasive materials, like steel wool pads. Keeping aluminum railings in pristine condition may require power washing twice annually, but regular care can greatly reduce the intervals between washing.
Lastly, it’s important to keep aluminum coated and protected from the elements. Most manufacturers offer touch-up kits that are nearly impossible to see when applied correctly should the powder coated finish get scratched.
Different types of low-maintenance composite deck railing options will require slightly different levels of maintenance. Overall, the maintenance required for composite railing is quite low. Use gentle soaps to occasionally scrub your railing with a soft bristle brush and thoroughly rinse off any chemicals used.
When comparing composite to wood railings, you’ll find composites have the advantage in most ways. However, it’s worth noting that, just like aluminum railing, the manufacturer is the authority in the best ways to keep their composite products clean.
Aluminum railing is typically available in fewer color options than composite. Most aluminum railing is offered in black, white, and a shade of brown. For example, Trex Signature® Railing provides three main railing color options. You can discover more aluminum railing color options here. However, despite the lack of color options, most aluminum railing manufacturers offer several designs that can set your project apart.
You can find a fairly wide range of color options for composite railing. For instance, Trex Transcend® Railing provides nearly twice as many options as the aluminum alternative. This extended range of colors usually allows composites to provide a better compliment to their surroundings. You can discover more composite railing color options here. On the other hand, most composite product lines offer fewer infill options compared to aluminum. It really boils down to what suits your tastes, project needs, and budget. Both products are excellent premium alternatives to wood that will provide years of low-maintenance enjoyment.
