Zinc-titanium advantages:
- durable for over 80 years,
- corrosion resistant,
- does not require maintenance,
- may be easily joined and formed,
- excellent for soldering,
- light and non-flammable,
- 100% recyclable.
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.
