Commonly Used in Manufacturing Cable Railing Hardware

The deceptively delicate look of cable railings masks their tremendous strength and durability. The stainless steel components used to fabricate the system are highly resistant to corrosion and designed for low maintenance, even in the face of harsh weather or fluctuating temperatures. When paired with the right framing materials, the look can match any aesthetic from a sleek modern look to a homier feel for mountain cabin living.

The primary material in most cable railing systems is 316L stainless steel, which has been engineered to be corrosion resistant in the presence of chlorides such as seawater or pool chemicals. Compared to other stainless steel grades, 316L is stronger and more ductile. For this reason, it is recommended for exterior applications where the system will be subjected to the elements and high loads.

For cable railing infill, the stainless steel hardware is spliced together using specific swaging tools to form a strong connection that is both visually appealing and structurally sound. This method of installation is often used for railings in residential applications because it is less expensive and easier to work with than welding. Most residential projects utilize 1/8″ and 3/16″ stainless steel cables, which provide a safe amount of visual opacity for the infill.

In order for the cable to be spliced, it must first be attached to the end and intermediate posts. Most cable railing hardware posts are constructed of either steel or aluminum and can be installed in a variety of ways. For example, some systems use a wood top rail for added warmth and a finished aesthetic while others utilize a stainless steel post cap for strength and visual appeal.

When it comes to mounting the posts and handrail, there are many different options available, but the most popular choice is a round tube that is made of stainless steel with a powder coat finish. This option offers the best combination of performance and value and is suitable for most residential applications.

One of the biggest concerns of installing a new stair or deck railing is maintaining the integrity of the structure over time. This is particularly true for stairs that are regularly climbed on. To address this concern, most manufacturers offer a warranty on their products. This warranty covers the life of the product against corrosion or structural failure due to manufacturer defect or workmanship.

The most important aspect of the warranty is that it requires that the customer maintain proper maintenance and care of the product, including regular cleaning and lubrication of the cable system. Failure to do so will void the warranty.

In addition, the customer must follow all local codes regarding the placement of safety barriers on stairs. These codes often call for double posts at the ends of a run to meet Code requirements and improve stability. Lastly, it is recommended that a spreader bar be mounted on the corner post assembly between runs that change direction to prevent buckling and improve stability.
