SilesiaZINC zinc-titanium sheet is manufactured in accordance with the PN-EN 988 standard and is available in three variants, differing only in the finish of the outer surface: NATURAL  – features a metallic, shiny surface that gradually develops a light grey matte patina over time due to exposure to atmospheric conditions. PRE-AGED GREY – features a matte, light grey surface with a patina created through a controlled chemical process. To avoid the transitional phase of natural patina formation, factory-patinated sheets are recommended for exposed architectural elements such as façades. PRE-AGED CARBON – a new type of patina with a shade close to graphite black, created through a complex technological process. This material contrasts beautifully with lighter colors, giving buildings a unique and distinctive character. It pairs perfectly with other materials, such as natural slate.
