Ready-to-Customize Composite Deck Railing: The Classic Composite Series

Featuring several top rail designs, four unique infill options, and multiple colors, the Classic Composite Series is your go-to railing for a totally curated design.

Get familiar with your options and learn how to customize your railing design.

Step 1: Choose Your Top Rail

The top rail you choose sets the tone for the rest of your railing design. Options range from traditional milled wood looks to sleek modern designs, so you’re bound to find the right fit for your aesthetic style.

Step 2: Choose Your Infill

While your top rail choice sets the tone for your design, your infill is just as important as it helps define the aesthetic for your curated space.  

Composite Balusters

Choose this for: A stately, traditional look with a strong silhouette

Aluminum Balusters

Choose this for: A narrower profile compared to composite for clearer sightlines and a more modern aesthetic.

Stainless Steel Cable Rail

Choose this for: An industrial-chic look that doesn’t compromise on safety or durability.  

Glass Panels*

Choose this for: A chic, minimalist aesthetic and a strong, shatter-resistant construction.

*Glass panels not included with railing system

Step 3: Choose Your Colors

The colors you choose for your railing give your design its finishing touch. Your color selection extends to your rails, posts, and composite baluster infills (aluminum balusters only come in black). You can choose the same color for all three or mix and match for a striking look. When choosing railing colors, think about other exterior colors, such as your home’s trim, and choose to either match or contrast them.

NOTE: Your available color options will depend on your top rail choice.

Classic Composite Series Color Options

For the following top rails, Premier Rail, RadianceRail, Drink Rail, and Trademark Rail (excluding the Contemporary Top Rail), your options will be: Matte White, Matte Espresso, Black, and White. You’ll also be able to choose many of these colors for the posts and composite balusters of your railing design, regardless of top rail choice.

If you choose the Drink Rail, you’ll also have the choice of any deck board color from TimberTech decking collections featuring full-profile, square-shoulder deck boards, for your deck board top rail.

Contemporary Top Rail Color Options

For the Contemporary Top Rail, your color choices are Traditional Walnut or Classic Black. Remember you can also choose many of the colors above for the posts and composite balusters of your railing design, regardless of top rail choice.

Quick Tips for Composite Deck Railing Installation

Once you’ve locked in your railing design, you may be wondering if you can put it together yourself. DIY-ing your composite deck railing can be a rewarding experience, but keep in mind certain railing designs and infill options can be more challenging than others to install on your own.

Before you decide to DIY your railing, be sure to:

  1. Read through the railing installation guide to determine whether you’re comfortable with the process.
  2. Check local building codes to ensure your railing will meet code requirements.
  3. Reach out to your local town hall to determine whether a permit is needed for your project.

If you decide a DIY build is within your skillset, here are some basic requirements to help you out:

Basic Requirements for Railing Installation

Railing guardrail height: Typically at least 36” above the deck surface. In some applications, such as residential decks in California, as well as many commercial applications, the height needs to be 42”.*

Space between balusters: Typically no more than 4”.

Space between bottom rail and deck surface: Typically no more than 4”, but can be no more than 2” in certain applications.*

*Always check with your local building codes department  before installing your railing.

Keep in mind that a railing is typically required on decks that are 30” above ground level (check local codes to get the exact height requirement for your area). However, even on lower decks, a railing can improve your deck’s safety as well as add a design element for a polished outdoor living space.
