At AEON, we recommend opting for a PVD finish where these are available. PVD, which stands for physical vapor deposition, and is also known as thin-film coating, is a specialist manufacturing technique where the coating is vaporized and deposited atom by atom onto the steel surface, forming a bonded, metal or metal-ceramic surface layer. 

In order to achieve a PVD finish, the coating process has to take place in a vacuum with specialist tooling and equipment, which is understandably more expensive than applying paint layers, and therefore not as available to customisation of colour; the radiator manufacturer will predefine the finishes available, rather than offering an ‘any RAL’ choice to the consumer. However, the end result is a highly durable, beautifully even finish that functions as part of the radiator itself; it will not tarnish, chip or corrode, just as the original stainless steel would endure.
