PVD Technology – Why Our Fittings Are a Lifelong Investment

Most people assume that the gold, black, or copper finish on stainless steel railing components is just standard paint or simple plating. This is a misconception that becomes painfully visible after just a few years of use.

In our products, we utilize the PVD (Physical Vapor Deposition) process—the most advanced method of stainless steel refinement in the world.

What is hard PVD? (Physical Vapor Deposition)

PVD is a process of physical deposition from a gas phase, conducted in a high vacuum. In simple terms: a metal (e.g., Titanium) is "evaporated" and then deposited onto the stainless steel, creating an incredibly hard layer.

Molecular Bonding: The coating doesn't just "sit" on the steel; it bonds at an atomic level. There is no risk of it chipping or peeling like paint.
Hardness: The surface becomes nearly as hard as sapphire.
Eco-Friendly: The process is entirely safe for the environment, involving no toxic chemicals.

What is "Standard" (Galvanic) Plating?

Traditional plating usually involves a chemical bath (electrolysis). A layer of another metal (such as chrome or nickel) is applied to the steel.

Surface Layer: It is merely a "shell" applied over the steel. Any impact or deep scratch can cause the plating to flake off.
Corrosion: If the coating is breached, the underlying material is exposed to the elements, leading to potential degradation—especially in outdoor settings.

What does this mean in practice?

Sapphire-Like Hardness Unlike standard plating, which creates a thin surface film, PVD bonds with the steel at the molecular level. This results in an extremely hard surface, making our glass clamps and standoffs resistant to scratches from rings, keys, or accidental impacts.
Fade-Resistant Color PVD coatings are completely UV-resistant. Even on railings installed on sun-drenched terraces, the color remains as deep and vibrant as the day it was installed. It will not tarnish or change hue over the years.
Resistance to "Harsh Conditions" Our components are built to withstand glass cleaning chemicals, road salt, and acid rain. Where standard plating begins to peel and corrode, PVD remains intact.
Eco-Friendly & Hygienic The PVD process is 100% eco-friendly (zero toxic wastewater) and hypoallergenic. It is the same technology used for surgical instruments and luxury timepieces.

Vacuum Metallization (PVD Metallization) vs. Hard PVD Coating

At first glance, these processes may seem similar because both fall under the technical term "PVD" (Physical Vapor Deposition). However, the similarities end there.

Hard PVD Coating is a reactive process that deposits a specialized ceramic layer. In contrast, Vacuum Metallization is simply the evaporation of a metal and its deposition onto a part (moving material from point A to point B without a reaction).

The primary differences lie in the process duration, the source material, and whether a chemical reaction occurs within the vacuum chamber:

Mechanical Superiority: Hard PVD coatings offer far better mechanical properties and resistance at the cost of a longer processing time.
Color Range: Hard PVD allows for a wider and more precise spectrum of colors.
Value: Due to the complexity and time required, Hard PVD services are more expensive than basic vacuum metallization.

These methods are not direct competitors because the durability of the finish is incomparable. While vacuum metallization is a budget-friendly aesthetic fix, Hard PVD is a structural refinement designed to last a lifetime.
