Zinc-titanium is a modern material produced of the highest purity zinc SHG 99,995% with additions of copper and titanium. Modern technology guaranties very good physical and mechanical properties and allows for wide range of application in building industry.
NATURAL – the metallic and shining surface which will gradually turn to a natural light grey zinc patina in response to localised atmospheric conditions.
PRE-AGED GREY – a matt, light grey patina surface created as a result of chemical processes. It is recommended to use pre-aged material on elements such as facades.
PRE-AGED CARBON – a graphite-black surface developed using a complex technological process. The contrasting dark patina provides a distinctive identity whilst harmonising with other building materials such as slate.

Creating a protective layer under the influence of atmospheric conditions, that is typical for zinc, causes zinc-titanium has incredibly long-life use and requires practically no maintenance. On initially shining, rolled surface appears patina that is a thin, measuring some micrometers, well adherent protective layer consisting of oxides and basic zinc carbonates.
Zinc-titanium is produced according to EN 988 standard, in two sorts of different surface finish:
- BRIGHT-ROLLED – metallic and shining surface, which will gradually turn into light grey mat patina resulting from the influence of atmospheric conditions,
- PRE-AGED – mat, light grey patina surface created as a result of chemical reaction in a technological process. It is recommended to use pre-aged material on exposed elements like façades.
