Low Maintenance

Stainless Steel Cable Railing

Coastal Tough. Virtually Invisible.

  • 1×19 marine-grade stainless steel cable (AISI 316) — ISO 2232 compliant
  • Swaged or threaded tensioner ends: hand-adjustable without special tools
  • Post spacing to 1,800 mm with intermediate stanchions for longer runs
  • Compatible with wood, aluminum, steel or concrete post structures
  • Cable tension ≥ 1,000 N per cable maintained over temperature range −20°C to +80°C
  • Zero paint, minimal cleaning — rinse with fresh water annually in coastal zones

Overview

Horizontal 1×19 marine-grade stainless steel cables stretched between precision-welded posts — the modern alternative to glass or pickets for deck, balcony, and staircase railings. Virtually invisible at any viewing angle beyond 3 metres.

Available Configurations

Through-Post Threading System

Cables thread through pre-drilled holes in welded steel posts. Clean aesthetic, cables appear continuous. Best for straight runs under 10 m.

Lag-End Swaged System

Factory-swaged lag screws at each cable end. Fastest to install — lag directly into timber or metal end posts. Popular with timber deck builders in the US and AU.

Turnbuckle Tensioner System

Stainless steel turnbuckle tensioners at each end post. Highest adjustability — retension cables on-site after seasonal movement. Preferred for long runs (>12 m).

Frequently Asked Questions

Does cable railing comply with IBC building codes in the US?
Yes, when correctly designed. IBC Section 1015 requires guardrail infill elements to prevent passage of a 4-inch sphere. Horizontal cables at 3-inch (76 mm) spacing comply when cable tension is maintained above the code threshold of 50 lbf per cable. We provide a compliance drawing with each US-bound order.
How do I tension the cables after installation?
Use a 13 mm open-end spanner to tighten until the cable deflects no more than 50 mm mid-span under a 50 N lateral load — this corresponds to approximately 1,000 N tension.
How long do stainless steel cables last outdoors?
Grade 316 stainless steel cable in typical outdoor environments has a service life of 25–40 years with minimal maintenance. In extreme coastal environments, we recommend annual fresh-water rinsing of cables and fittings.
