I enjoy approaching issues from the customer's perspective, so the blog posts can address many customer pain points. Feel free to leave a comment to suggest topics for the next posts.

When it comes to stainless steel, there are many different types of finishes that you can choose from. One of the most popular finishes is PVD (physical vapor deposition). This finish is available in a variety of colors, and it is very durable. However, some people are concerned that the PVD colors will fade over time. In this blog post, we will answer the question: "Will PVD colors of stainless steel sheets fade?"

What is PVD and what colors are available?

PVD stands for Physical Vapor Deposition. PVD is the process of depositing a thin film of material onto a substrate. This can be done using a variety of methods, but most commonly, PVD is performed in a vacuum chamber by evaporating the material onto the substrate.

PVD coatings are available in a wide range of colors, including gold, rose gold, black, grey, sapphire, emerald, pink, violet, red, rainbow, light bronze, and copper. In addition to color options, PVD coatings can also be applied to all stainless steel sheets with surface treatment, such as mirror-finish, brushed(hairline/satin), vibration, sandblasted, embossed, stamped, etched, etc. Whether you’re looking for something subtle or eye-catching, there’s sure to be a PVD coating that’s perfect for your projects.

What is the production process of PVD-colored stainless steel sheets?

The first step is to put a crucial item(shown in the picture below) in the vacuum chamber, which is known as a titanium block. Following that, clean stainless steel sheets without any surface stains are hung in the rack of the vacuum chamber. After that, one type of gas is injected into the vacuum chamber. The titanium block is vaporized to release microelements when it gets heated up inside the chamber, and these elements combine with the introduced gas to form various colored compounds that adhere to stainless steel plates’ surfaces. The color produced depends on the type and amount of gas used.

What factors might affect the lifespan of a PVD color on stainless steel sheets?

The time of the PVD coating

There are instances when stainless steel is put into a PVD coating process without adequate time. As a consequence, the plating layer becomes unstable and the color fades more rapidly. The thicker the oxide layer allows the steel to acquire a higher grade of color output, which lowers the risk of fading over time as long as the duration of the stainless steel color coating procedure is longer. In other words, a thicker PVD coating will usually last longer than a thinner one.

The type of stainless steel sheet used

The type of stainless steel affects the lifespan of PVD color because it determines how well the PVD adheres to the metal. If you use a less expensive, lower-quality grade of normal stainless steel sheet, the PVD may not adhere well to the surface. On the other hand, if you use a higher quality stainless steel sheet, such as 304 or 316, the PVD coating will adhere better and last longer.

The environment

Stainless steel isn’t completely rust-free. When the acidity in the air exceeds the range that the stainless steel material can withstand, it’s possible to get rusted. In addition, long-time exposure to sunlight or other sources of ultraviolet light can also cause the PVD coating to break down over time.

Therefore, it is highly recommended to apply a layer of anti-fingerprint on the PVD color to protect it from sunlight and rain, which can greatly prevent the color from fading.

Regarding the construction materials, the bathroom is one of the important places to test its performance. Although PVD-colored stainless steel sheet is subject to a series of various surface treatment processes to increase their corrosion resistance, any material placed in dark and humid conditions, if not enough maintenance, will eventually be oxidized.

In a word, if installed indoors, anti-fingerprint PVD color stainless steel sheets in 304 or 316 grade will not fade. If outdoors, not near the sea area, it will not fade easily either, but it is recommended to do a layer of anti-scratch treatment that protects the surface more thoroughly.

How to care for your color stainless steel sheets

Even though a surface color coating may improve salt spray corrosion resistance and chemical corrosion resistance, exposing your metal to damp or corrosive conditions without sufficient care will further damage it, resulting in a loss of hue.

Here are a few tips on how to care for your colored stainless steel sheets:

  • Wipe them down with a damp cloth after each use
  • Avoid using harsh cleaners or abrasives on them.
  • Don’t leave corrosive acids or alkalis on your stainless steel substrate for an extended period of time, as this will cause the color to fade.

By following these simple tips, you can keep your coloured stainless steel sheet looking new for years to come.

What are the benefits of using PVD colors on stainless steel sheets?

There are many benefits of using Physical Vapor Deposition or “PVD” colors on stainless steel sheets over traditional methods like painting or powder coating metal surfaces.

  • A More Durable Finish: One key benefit is that it creates a much more durable finish. This is due to the fact that the PVD color finish is applied through a process of ion deposition. The result is PVD colors are more resistant to wear and tear, meaning they will last longer and make them a good choice for high-traffic areas.
  • More Consistent and Vibrant Colors: The PVD coloring process allows for a wider range of color options and effects. PVD colors can also give your stainless steel a unique look that is not possible with traditional methods.
  • Withstand high temperatures: The PVD coloring process actually makes the stainless steel stronger and able to withstand high temperatures without discoloration or damage.

Overall, PVD colors offer superior performance and aesthetics compared to traditional finishes. Contact us today to learn more about our PVD color options! We would be happy to help you choose the perfect finish for your project.
