elZinc Astur® is the originally metallic grey finish produced by our production process. Once exposed to the elements, elZinc® naturally develops a compact protective layer called “patina”.
This patina provides exceptional resistance to corrosion, resulting in the gradual loss of its metallic lustre until it takes on its characteristic matt grey colour.
The final shade of the colour largely depends on the environmental conditions to which it is exposed, as particulate matter and dust in the air are drawn into the patina.
