What Is a Deck Railing System?

Your railing is actually made up of multiple rails – as well as other interconnected components. Knowing the names and function of the different components will help you decide which of the deck railing systems available are right for you.

What Types of Deck Railing Systems Can I Choose?

With TimberTech, you have your choice of two deck railing materials: metal railing or composite railing. Each offer their own benefits and design options.

Benefits of Both Aluminum & Composite Railings

Low maintenance: No costly or labor-intensive sanding, staining, sealing, or painting required.

Value added over time: Although the initial cost of composite and aluminum deck railings may be higher than that of pressure-treated wood railings, less maintenance means more savings. You’ll see lower lifetime costs compared to wood railings.

Aesthetic beauty: With profiles ranging from classic to contemporary, our full railing portfolio has just what you need to complement your outdoor living space.

Composite Deck Railing Systems

With a portfolio ranging from the tailored and traditional deck railing systems of the Classic Composite Series to modern options like the Contemporary Rail or Builder Rail, you can find the right composite railing for your backyard build.
