Zinc
We make our roofs out of the finest materials. They are composed out of 275g/sq.m. or G90 of hot zinc coated one of the most reliable and lasting materials that will stand up to any weather and time without any signs of rust, wear or tear. This amount of Zinc (~20 micrometers on each side) is European standard for outside use of metal.
With a zinc coating you fight corrosion in two fronts. Firstly, coating serves as a protective layer which does not let oxygen and water contact the steel. Secondly, it also makes a cathodic protection. Let’s imagine the metal sheet was damaged through or at its edge, zinc will form protective compounds and immediately stop corrosion process.
