PVD technology is widely used in building materials industry. It not only brings more colors and texture to building materials products, but also brings super performance. Stainless steel plate and pipe are widely used in building materials industry. The monotonous stainless steel color can be more colorful by PVD coating. At present, stainless steel building materials products mainly include stainless steel plate and stainless steel pipe. The plating colors are titanium gold, champagne gold, light bronze, zirconium gold, rose gold, rose red, bronze, red copper, grey black, gun black, purple gold, dark brown, sapphire blue, tea, dazzle color, stainless steel, coffee, violet, violet, grass green, etc. At present, the high-grade building materials products in the market are using PVD technology for surface color treatment. With the improvement of people's requirements for life quality, the proportion of PVD building materials products is increasing year by year. In addition, with the attention to environmental protection, especially the demand to replace water electroplating, the application of PVD will be more and more widely.
