In coastal and high-pollution environments, door hardware is under constant attack from the elements which can affect its appearance and functionality.

Marine grade stainless steel is a popular choice for these environments due to its excellent corrosion resistance.

However, even the best materials can benefit from additional protection. This is where Physical Vapour Deposition (PVD) coatings come into play.

What is PVD Coating?

Physical Vapour Deposition (PVD) is a process that creates a thin, yet highly durable coating on metal surfaces. The process involves the vaporisation of solid metal into a gas, which is then deposited onto the surface of the stainless steel in a vacuum chamber.

The result is a coating that is not only aesthetically pleasing but also exceptionally resistant to wear and environmental factors.

Benefits of PVD Coatings on 316 Stainless Steel

1. Superior Corrosion Resistance

316 marine grade stainless steel is renowned for its corrosion resistance due to its high molybdenum content, which means it can withstand chlorides and industrial pollutants.

PVD coatings take this protection to the next level. By creating a barrier on the surface, PVD coatings prevent oxidation and corrosion, even in seaside and high pollution environments.

This makes PVD-coated door hardware an ideal choice for coastal homes and buildings in urban areas with high pollution levels.

2. Resistance to Fingerprints and Deposits

One of the practical advantages of PVD coatings is their resistance to fingerprints, grease, and other deposits. The smooth, non-porous surface created by PVD minimises the adherence of oils and dirt, keeping your door hardware looking clean and new with minimal effort.

This feature is particularly beneficial in high-traffic areas where frequent handling can lead to unsightly marks and smudges.

3. Low Maintenance and Longevity

PVD-coated hardware requires significantly less maintenance compared to uncoated alternatives.

The durability of the coating means that it won't chip, tarnish, fade, or wear off easily, even under harsh conditions.

This longevity reduces the need for frequent replacements or touch-ups, providing long-term savings in both time and cost. Furthermore, cleaning PVD-coated surfaces is typically straightforward and involves nothing more than a simple wipe with a damp cloth.

Brass PVD Finishes for Door Hardware

When it comes to door hardware, aesthetic appeal is as important as functionality. PVD coatings offer a range of finishes that can complement any architectural style while providing superior protection.

One of our most popular is the brass finish stainless steel. It combines the aesthetic appeal of traditional brass with the durability and corrosion resistance of 316 marine grade stainless steel, offering the best of both worlds.

The PVD coating process deposits a thin layer of brass-coloured material onto stainless steel surfaces. The result is a warm, golden hue that mimics the classic look of solid brass without its susceptibility to tarnishing and wear.

Additionally, this finish benefits from the inherent strength and anti-corrosive properties of stainless steel, ensuring that the beauty of the hardware is preserved even in harsh environments.

1. Polished Brass

For those who prefer a more traditional look, polished brass provides a classic, elegant appearance.

The PVD process ensures that the rich, golden colour of brass is preserved without the typical tarnishing that can occur with untreated brass.

This makes polished brass an excellent choice for heritage homes or spaces that aim to convey luxury and warmth.

2. Satin Brass

Satin brass offers a softer, more muted alternative to polished brass, combining the traditional appeal of brass with a contemporary matt finish.

This versatile option blends seamlessly with both classic and modern designs, offering a timeless aesthetic that complements a wide range of architectural styles.

Conclusion

PVD coatings enhance the performance and appearance of 316 marine grade stainless steel door hardware, making it an ideal choice for harsh environments.

With their superior corrosion resistance, low maintenance requirements, and range of attractive finishes, PVD-coated hardware stands as a reliable, stylish, and durable option for any setting, particularly in high-pollution and coastal environments.

Whether you prefer the timeless elegance of polished brass, or the modern appeal of satin brass, PVD coatings provide the protection and longevity your door hardware needs to withstand the elements.
