The quality management system in force at our plant has been reviewed and evaluated and meets the requirements of  DIN EN ISO 9001.

Production processes are monitored continuously to ensure uniformly high product quality.

Our staff has gathered many years of experience, which is supplemented by continuing advanced training. Their competence, coupled with management’s continuous efforts to improve technological processes, guarantee high quality.

We have earned the certificate for “Hot Dip Galvanized Building Components Made of Hot Rolled Structural Steel and Hot Dip Galvanized Die-Cast Steel” issued by the Institut für Oberflächentechnik GmbH, Schwäbisch Gmünd, upon completion of the review and inspection required for award of the Seal of Conformity (“Ü-Zeichen") with the provisions of Construction Regulations List A, Part 1 (version 1999/1).
 
We are members of Industrieverband Feuerverzinken (German Galvanizing Industry Association).

Environmental care is a fundamental aspect of everything we do. 
 
Exhaust heat is recovered with heat-pump systems. This significantly reduces energy consumption.
 
Waste materials are returned to the processing cycle or recycled. No waste water from our production facilities is diverted into the sewer system.
 
Modern exhaust and filter systems guarantee consistent compliance with European environmental protection laws.
