Provexa Earth®

Provexa Earth® is basically a high-alloy zinc coating. A nickel-free method that, among other things, protects against corrosion. The surface protection utilizes the natural oxidation processes that take place upon contact with air. The coat consists of zinc, iron and manganese and is normally between 5-8 µm. The result is great environmental benefits and properties that are better than traditional surface treatment with zinc nickel.
