PVD Violet Coating Process
PVD violet color coating on mirror stainless steel is made of 304 2B/BA stainless steel, processed by polishing and grinding process and PVD vacuum plating process, so that its surface can achieve the effect of mirror violet. This kind of mirror violet color stainless steel not only has a super mirror effect, but also has good corrosion resistance and acid resistance, and is the best choice for interior decoration materials.
Mirror Finish Benefits
The mirror finish not only provides an aesthetically pleasing appearance but also offers practical benefits such as easy cleaning and maintenance due to its smooth surface. It can reflect light and create a sense of spaciousness, making it popular for various design applications.
