General Composite Railing FAQs

Why Should I Choose Composite Railing For My Deck?

Composite railing is an awesome, low-maintenance deck railing option that captures the traditional look of wood without all the upkeep demands. If you have a cape cod-style home or a classic-looking deck, composite railing will be a perfect fit that will hold up for years. In addition to its traditional style, composite material is super durable and ultra low-maintenance, making for a premium deck railing.

What Parts Make Up Composite Deck Railing?

Composite deck railing is made up of (1) rails, (2) posts, and (3) infill, as shown below:

Rails are the long, horizontal bars - most composite railing systems will have a top rail and a bottom rail. Posts are the thick, vertical pieces that give your railing strength (With composite railing, the posts are often wood or metal structural posts with a composite post sleeve around them). Posts and rails create a square or rectangle; infill sits inside that square or rectangle. Infill can be balusters - smaller, vertical bars parallel to your posts. But railing can also use glass balusters, glass panels, or metal cables as infill.

What Is Composite Railing Made Of?

Composite railing, like composite decking, is a blend of natural wood fibers and synthetic plastic. The result is a material with the rich, organic look and feel of natural wood, but with a significantly longer lifespan and far less regular maintenance. Unlike wood railings, composite railings never need to be stained, and they won’t rot, crack or warp over time.

The other big advantage of composite material is that it is often made with recycled materials for a more sustainable, eco-friendly railing option that doesn’t contribute to deforestation.

What’s The Difference Between Composite And Vinyl Railing?

While composite material is a mix of natural wood and synthetic plastic, vinyl railing is made entirely from synthetic material. As a deck railing, the two share a lot of advantages: both composite and vinyl railings are low-maintenance and durable. The main difference comes down to style. Composite railings have more of a natural wood look and a traditional style. Vinyl railings tend to have a glossier finish, and fit well with colonial homes.

Composite Railing Design

Can Composite Deck Railing Have A Drink Rail?

Yes. Our composite railings feature a number of railing lines with drink rail adapters. Trex Select is a standout, with a white-and-black look that can really shine with a composite deck board of your choice attached on top as a drink rail. You can customize your TimberTech Classic Composite Railing to feature a drink rail, and the TimberTech Classic Composite system works with composite balusters, metal balusters, glass panels or stainless steel cable for an incredibly versatile setup.

Can I Paint Composite Railing?

We wouldn’t recommend painting composite railing, as this can void your warranty. Fortunately, we carry systems like Trex Transcend that come in a huge range of color options to fit the style you’re looking for in your outdoor space.

Can I Use Cable Or Glass Infill With Composite Railing?

Yes! Composite railing can work with a variety of infill options, based on the composite deck railing system you choose. For example, Trex Transcend can pair with full glass panels for a composite and glass railing setup. So can TimberTech Classic Composite Railing. You can also combine TimberTech's composite railing with Feeney CableRail for a modern cable setup. Composite railing makes it easy to mix and match different railing materials: several composite railing lines also offer aluminum balusters for strength and style.

Composite Railing Maintenance

How Much Maintenance Do Composite Railings Need?

The huge advantage of composite railings is that they are extremely low-maintenance. Weathering the elements much better than wood, composite deck railings don’t rot, warp, or crack, and you’ll never need to stain or paint them. That means you can spend more time enjoying your outdoor living space and less time on regular chores to maintain it.

How Do I Clean Composite Railing?

Composite railings are easy to clean - most of the time, normal soap and water are all you need to make your railings sparkle. We recommend cleaning them at least twice a year. Just spray down your railings with a hose to remove surface debris, wipe them down with warm, soapy water, and then rinse all the cleaning solution off with fresh water again.
