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.
