The difference lies in the combination of the quality of the basic raw material, AISI 304 steel, and the choice of precious metals that, after undergoing the sublimation process (Physical Vapor Deposition), physically melt with the surface layer of the steel, creating a protective crust of golden, metallic or copper colour, depending on the metal powders used.
In fact, Foster PVD Gun Metal, Gold and Copper colours stand out for their unique shades. Foster has chosen to apply the PVD treatment on AISI 304 Satin and Vintage steel finishes. The surfaces of Foster products are all treated with special brushes made entirely of vegetable fibers that smooth the material without scratching it in depth. This aspect is fundamental in order to obtain surfaces that are extremely shiny and guarantee greater hygiene.
