Deck Railing Design Ideas
Choosing a deck railing design is putting the icing on the cake of your deck-building project. You can add a railing system that matches the material of your deck, or mix it up, like adding a colorful powder-coated aluminum railing to your redwood deck.
Whatever you come up with, remember that building codes have a lot to say about how to build a deck railing. Railings are required on decks that are 30 inches or more above grade, railings must be at least 36 inches high, and balusters must be no more than 4 inches apart.
With the codes in mind, here are basic types of deck railings:
Composite + Vinyl
Composite and vinyl deck railings come in many styles and colors, and are virtually maintenance-free. Railing kits have posts, balusters, rails, and connectors that make installation a DIY-friendly project. The structural core of the system are pressure-treated wood posts covered with a composite or vinyl sleeve, and some systems offer mix-and-match baluster materials, such as steel and aluminum spindles. Composite and vinyl kits are readily available at home improvement centers for $25 to $30 per linear foot.
At $40 to $60 per linear foot, glass makes an oh-so-chic but oh-so-expensive deck railing system. Nevertheless, they’re great when you want to see all the vistas your deck has to offer. Use tempered, shatterproof safety glass, but check with your local building codes about glass railings before you proceed. Look for modular railing systems with aluminum posts and supports. Choosing tinted glass helps prevent birds from flying into clear glass.
Modern Glass Deck with 360 Degree Views
To coordinate the modern interior of this seaside retreat with its exterior counterpart, designer Madelyn Simon used metal, glass and mixed wood as her primary materials. She used the wood planks as deck flooring and created an enclosed railing with glass and metal to ensure the ocean views would be in clear view from every angle.
Metal deck railings are made of either powder-coated aluminum or steel. Both are rugged, but only aluminum is rustproof. Metal deck railings that you find at home improvement centers come in a limited number of styles and colors. Expect to pay $30 to $40 per linear foot for a metal tailing system.
Cable deck railing systems are another good way to open up views, and to give your deck design a modern aesthetic. They include stainless steel cables and posts made of wood, aluminum, or composites, and a system runs about $125 to $150 per linear foot. The cables run through intermediate posts and usually end at a corner where the cable is attached to a turnbuckle for creating — and maintaining — the correct tension. To comply with codes, the cables must be no more than 4 inches apart, so maintaining the proper tension is vital.
Wood railings run the gamut from inexpensive to downright pricey, depending on the wood you choose. Pressure-treated wood is the most budget-friendly, at about $10 per linear foot for a railing system. Tropical hardwoods such as ipe run up to five times as much.
