The benefits are a more impact and scratch resistant finish, but it’s not bullet proof. This sounds great, but don't misunderstand. The PVD (Physical Vapor Deposition) surface treatment is quite durable, and is actually harder than the stainless steel surface itself. Available Materials for Color Stainless SteelĬolored stainless steel from Double Stone is available in 304 and 316 stainless steel and offers an attractive finish for general (304ss) and harsh environments (316ss). With the newer PVD technology entering the marketplace today via Double Stone, there is finally a coloring solution for stainless steel that can replace any other, with superior results that can actually be warrantied. The coating process itself has much lower environmental impact than any dipping, electroplating, galvanizing or liquid coated application process, and there are no toxic chemicals to worry about or clean up. Environment Implications of PVD Coated Stainless Steel However, the long and short is that you as an architect, builder, contractor, project owner, or end user can be confident you are getting the best product available, and you will not need to be calling us back for rework, color issues, etc. Of course, you'll need to document the purchasing, fabrication and installation of the product to ensure the supply chain remains intact once you purchase from JTC Metals. The available anti-fingerprint coating is extremely easy to clean and is fantastic for areas prone to graffiti as it's hydrophobic and is difficult to paint or color on.ĭouble Stone is one of a few companies willing to warranty their PVD Stainless steel and offers warranties up to 30 years, depending on the installation circumstances. It is also excellent as a secondary coating to the stainless steel as chemicals and detergents generally do not affect the finish. PVD coated stainless steel is excellent for both indoor and outdoor use as it maintains the color over many years, and will not change color when exposed to UV, if it's done correctly. The point is your elevator, sky scraper, or corner guards will be the desired color, and not some random shade that would leave you with a tarnished reputation. Fortunately, you can spec our Gun Metal, Rose Gold, or Copper colors, to name a few, and expect to receive the same color now or in the future. However, the PVD process also has to be carried out correctly in order to achieve this level of uniformity. None of the dipping processes can guarantee that and it's something to ask about when you're sourcing. Unlike LIC (light interference coloring) and electroplating, PVD can actually be specified from project to project without having to worry about colors changing or whether the color will change from sheet to sheet. We understand you have other issues to think about than a subpar product, and the last thing we want is a call about a failed installation. If something changes, you'll be the first to know as we use Double Stone PVD in our own projects and/or products.
The PVD market leader today is Double Stone Steel and we're glad to be able to offer the product in North America. At that point, it's far too late to be looking for the right solution. You will not be able to tell the difference between a low quality PVD product or a high quality PVD product until it's been installed in the field. It's very difficult to do correctly and experience is a must. This is an extremely basic explanation of PVD. It is achieved by placing the product in a vacuum chamber and heating a proprietary blends of metals and compounds causing them to vaporize and pulling them across the chamber with magnets to create a uniform and ultra-tough coating on the product being coated.
There are many methods for coloring metals, but the process for coloring stainless steel known as PVD - Physical Vapor Deposition is by far the toughest and longest lasting available today if done correctly.
