Black finish
The treatment that provides the black color is known as Physical Vapor Deposition (PVD). It is a coating method that consists of depositing thin films of different evaporated materials on the stainless steel surface of the drain. The coatings are ceramic, withstand high temperatures and good resistance to corrosion, impact and abrasion. They are also impermeable to ultraviolet degradation, do not fade and are very harsh in acidic, alkaline and salt bath environments, nor are they damaged by chemical and cleaning products. Dangerous by-products are not used so the PVD system is ecological and environmentally friendly.
