If you lean against a cable railing, you’ll feel that the cable is taut. It’s installed to run through the posts and securely resist any weight that is put on it. That said, you may feel the cable move slightly when you lean into it. That’s because quality steel cables are slightly elastic. They’ll give a little bit, but that doesn’t stop them from securely holding up to 15,000 pounds. That is, if the cables are tight enough and properly installed. So, just how tight should the cable railings be?
Building Code Requirements for Cables
Building codes require the cables in a cable railing system to achieve a specific tension. For example, many codes do not allow cable railings to deflect or bend more than four inches away from one another. A four-inch sphere should not be able to pass through your cable railing for safety reasons. With our service areas that include Pleasanton, San Ramon, Concord, Sunnyvale, and much more, find out what requirements are needed for your building.
Sagging or Warping Isn’t Okay
Even the highest quality cables will deflect slightly, as they are supposed to. However, a cable that is constantly sagging, without anything leaning against it, is a safety concern. Further, a sagging or warping cable really detracts from the overall looks of the property. Whether it’s your home or business property, a cable that isn’t tight enough can undermine your efforts to keep the property looking sharp.
Properly installed cable railing systems should never sag, warp, or buckle. We can achieve these high-quality railings by using better cables, better posts and installing the system with great attention to detail.
For cables, preventing sagging is simple. While other companies might use vinyl-coated or galvanized cable, we use marine-grade cable. Unlike the others, marine-grade steel grade cables will not deteriorate in ultraviolet light from the sun. They’ll maintain their integrity for years, so you don’t have to worry about them sagging or even buckling in the future.
