Best Overall Composite Deck Railings

You'll notice a theme in our list. Two huge brand names dominate the composite railing market: Trex and TimberTech. These brands have led the outdoor living industry for years, so it's no surprise they've each developed high-performing composite railing systems

Here are our two favorite composite railing systems of the year:

Best Composite Railing: Trex Transcend

Reasons you'll love it:

  • Premium-quality railing
  • Tons of color options you can mix and match
  • Traditional style and color options that look great on any home
  • Easy to customize with drink rail, Trex lighting, handrail, gate and more
  • Many style options from round balusters to square balusters to glass panels to distinctive mesh looks

Trex Transcend is totally classic. The Trex brand has perfected a timeless, traditional look that's consistent across everything it produces, from decking to railing to lighting and more. In true Trex fashion, the Transcend railing system delivers that look to a "T".

Transcend is everything composite railing should be. Thick, sturdy post sleeves mirror the classic, substantial look of wood posts, but eliminate the regular staining, painting, inspecting and maintaining needed to keep wood posts strong and attractive. The top and bottom rails are substantial and traditional. And the installation is simple and straightforward.

What really sets Trex Transcend apart is its customization in color. The system comes with three different color options for your top and bottom rail, and you can mix and match those with six different color options for post sleeves. Coordinating with the colors already existing in your home and deck is easy.

From a bright, airy white (shown above) to a sleek, modern black (shown below), you can create any look with Trex Transcend. We especially love white trim with the brown Vintage Lantern rails which you can see at the beginning of this section.

Trex has led the outdoor living industry for decades, so Transcend Railing is incredibly easy to trust for performance. It holds up extremely well in even harsh outdoor climates, only requiring some regular light cleaning to shine like new.

And the best part about all those colors? You'll never need to paint or repaint to keep them bright.

  • Distinctive, desirable looks for premium, luxurious decks

Our other favorite composite railing system is all about standing out. TimberTech's Classic Composite Series is an infinitely customizable composite railing that you can perfectly tailor to your desired style to look like nothing else in the neighborhood.

The top rail determines a lot of the character of your deck railing. What's great about TimberTech Classic Composite is that the system offers not one, not two, not three, but four different top rails you can choose from.

Around the industry, TimberTech is known for premium, high-end looks. If you want to add a dash of luxury to your deck, TimberTech's Classic Composite Railing is the way to go.

If you've got a specific budget in mind, check out these composite railing options that deliver a little less customization, but maximize the look and performance you get at a lower price.

Best Value: TimberTech RadianceRail Express

Where most composite railing systems are big and substantial, the TimberTech RadianceRail Express line offers a unique look. RadianceRail Express slims down the look with thinner posts and rails that look a little more modern and also keep costs lower.
