Metallic coatings

Rock solid, right from the start

Even with the large variety of our products, our building systems made of steel share one thing in common: the metallic coating for the best corrosion protection and exceptional long product life.

Hot-dip galvanised fine sheet is the ideal starting material for the paint coating in a continuous process and our raw material suppliers produce the following versions:

The pre-requisite for a lasting attractive appearance is the high-quality standard of the finishing. The new metallic coating ZM EcoProtect with a proportion of around 1 % magnesium sets these standards. Combined with the numerous organic coating systems, you can rely on a protective effect lasting more than 30 years.
