Cable railing is a popular choice with my clients when I’m working on a contemporary home’s deck. The narrow cables and minimal posts give an open, airy feel that can help maximize a view while looking sleek and clean in a way that matches and complements a home’s style. On top of these benefits, the right railing system offers easy installation and can be pretty cost efficient.
But there are a lot of options when it comes to choosing a type of cable railing. Should you choose horizontal or vertical cables? Do you want metal posts or wooden ones? In my mind, the most important decision is your cable material. Using the wrong type of cable can result in a railing that looks worn before its time or, even worse, is unsafe. Most cables for cable railings are made of stainless steel, but that’s not the only choice. Here’s the lowdown on what you’ll have to choose between and which direction to go.
Choosing Your Cable Railing Material
While you also want to pay attention to the material you choose for the cable railing’s posts (and top and bottom rails, if your system has them), it’s critical to pay special attention to the material that makes up the cables themselves. There are big quality differences here and they’ll affect how good an investment your railing choice is. In most cases, you’ll see three different options:
- Vinyl covered: Vinyl-covered cable will usually use a lower grade steel core along with a vinyl coating over the top. I’m not a fan of this particular option, as it tends to crack and break down in bad weather. Plus, there’s a lot of tension in your cables once they’re set, and vinyl just doesn’t have the durability to hold up under pressure over time. On top of that, this type isn’t very good if you’re using horizontal railing. In this case, the cable needs to make a 90-degree angle, and the angle will speed up how fast the vinyl wears out. Once your coating cracks, the steel inside will eventually rust.
- Galvanized steel: A step up from vinyl-coated cable wiring is galvanized steel, which some may use because it’s a much cheaper option. However, basic steel wire like this will inevitably corrode and break down over time, eventually losing its tension and needing to be replaced. In the end, when you use galvanized steel to save on initial costs, you pay more for maintenance, since you’re going to have to replace those cables eventually.
- Stainless steel: Stainless steel is the best option for getting the job done and keeping your railing strong for years to come. It’s capable of standing up against almost any element, ensuring it won’t crack or fade over time, and gives you the best maintenance-free option for your railing system. But there isn’t just one kind of stainless steel. Stainless steel is an alloy (a mix of iron and chromium, plus a few other elements) and the chromium and other added elements are what make it shiny and resistant to rusting and pitting. It’s what your stainless pots and pans and silverware are probably made of. Some manufacturers make railing cables out of stainless, and this is the stuff I look for when I’m choosing a cable railing system.
As you can tell, I have a definite opinion about which type of railing cable is the best--I’ve seen how well marine-grade stainless holds up, and I think it’s the clear choice. But before you go buy and install that stainless cable system, there are a few additional things you should keep in mind.
Design and Safety Considerations in Cable Railing Installation
Installing cable railing is much different than installing picket-style railing systems like steel or wood. It can be a bit more complex and expensive if you’re new to the process. You’ll need to remember that:
- Railing posts must be designed to specifically work with a cable system: Cable railing systems will have different load requirements than picket railing systems do, as most of the pressure from the cables is going to be on the posts in the railing. The cables need to have enough tension to keep them from being squeezed apart (for child safety reasons, railing systems cannot allow a sphere 4 inches or larger between the balusters), and your posts need to be able to hold that tension. Otherwise, you could risk losing the tension in the cables (and failing inspection) or causing the posts to bow.
- Creating your own system is dangerous if you’re not an expert: I’ve already touted the benefits of pre-assembled cable railing systems that have the cabling already attached to a panel with a sturdy frame. If you’re not an expert, that’s the way you should go. Creating a railing system from scratch using cables can be extremely complex (not to mention frustrating), and if done incorrectly, is unsafe. In well-designed panel form, though, a cable system can be one of the easiest deck railings to install.
- Choose vertical cables if you have kids: Most cable railing systems are horizontal, but some are wary of this type of system because of the “ladder effect.” Horizontal cables create a ladder that can tempt kids--and even pets--to try to climb them. For many parents, this is a hassle they’d rather avoid. For these clients, I recommend vertical cable systems that include pre-assembled vertical panels.
With cable railings, a solid frame teamed with marine-grade stainless steel cables offers a minimal rail profile that’s safe and essentially maintenance free. While there are a lot of options out there for cable railing, choosing a panel system that uses stainless steel will offer the easiest installation with the most durability.
