Since the mid-90’s, physical vapor deposition (PVD) coatings have been established as the high quality finish for sanitary and door hardware in the U.S.

PVD is a vacuum deposition technique where metal is vaporized in an atmosphere that consists of partly ionized noble or reactive gases. In the first case, a metallic layer is grown on the substrate material. In the second case, the metal reacts with the ionized gas, leading to a ceramic material.
