Cable Railing
Product Types
Cable railing systems provide a modern and open look using tensioned stainless steel cables as infill between posts. These systems are ideal for maximizing views and natural light in locations such as decks, terraces, balconies, and interior staircases. The horizontal or vertical cables create a sense of openness while still ensuring user safety.
Designs may include wooden, metal, or composite posts and rails. Because of their flexibility, cable railing systems are often chosen in residential projects or outdoor settings where unobstructed views and airflow are prioritized.
Material
The core of these systems is marine-grade stainless steel cable, usually 1/8″ to 1/4″ in diameter. The cables are attached with threaded terminals, turnbuckles, or swaged fittings, which allow for fine tension adjustments. Posts are made from stainless steel, aluminum, or powder-coated steel.
End and intermediate posts are structurally reinforced to handle cable tension. Top rails may be wood or metal, depending on the design preference and required rigidity. All components are selected for long-term weather resistance and structural strength.
Load & Safety
Cable railings must be tensioned properly to comply with safety standards. Sagging or excessive spacing can create hazards, especially for children. Most codes require a maximum horizontal opening of 4 inches to prevent fall-through.
To resist applied loads, the cables are installed under high tension and supported by solidly anchored end posts. Intermediate posts or cable spacers are used to prevent deflection under pressure. When properly designed and installed, cable systems are as safe as traditional railings.
Maintenance
Cable railing systems require periodic maintenance to retain their appearance and performance. Tension may need to be adjusted seasonally due to thermal expansion or structural movement. Cables and fittings should be inspected regularly for signs of wear or corrosion.
Cleaning is relatively simple: cables can be wiped with a damp cloth, and metal posts cleaned using mild detergent. Avoid using harsh chemicals or abrasives that could damage the stainless surface or compromise mechanical connections.
Durability
Marine-grade stainless steel cables are exceptionally durable and can last for decades in outdoor environments. Their resistance to UV radiation, rain, and salt spray makes them particularly well-suited for coastal or marine applications.
With proper design, tensioning, and care, cable railing systems provide a long-lasting and visually appealing solution that retains its structural integrity even in demanding conditions.
