Innovation is part of our identity. It has resulted in patented technologies that are used extensively across industry, such as the Fürstenberg-Permadur^®-System, which provides reliable protection for wooden poles against mechanical and biological damages. Wooden poles are protected with metal foil and a shrink sleeve in the sensitive ground/air zone.

Thanks to continuous research and development we are able to ensure high quality of our products, and to protect the renewable wood resources.
