The ONYX Series is Atlantis Rail’s

RailSimple line of black cable railing and hardware, combining sleek style with unmatched performance. Each component is crafted from high-quality 316 stainless steel and treated using Physical Vapor Deposition (PVD). This cutting-edge process delivers superior durability and a rich, long-lasting black finish.

After extensive research, development, and testing, Atlantis Rail selected PVD coating over traditional black oxide due to its enhanced resistance to wear, corrosion, and fading, along with its refined appearance and overall value. The result is a modern black finish that stands up to the elements while maintaining the premium look and reliability you expect from Atlantis Rail Systems.

If you’re looking for high performance, low-maintenance, and long-lasting stainless steel cable railing fittings—PVD is the superior choice, especially in outdoor or architectural applications.
