Reliability is based on a solid foundation

Reliable, loyal and respectable are they – the people of Siegerland. We don't make a big song and dance, but prefer to rely on committed team players, who work in equal measure for both our company and our customer. Local employees have helped to write our company history of more than a century with healthy economic activities and well thought-out decisions. Our focus has always been on looking to the future and adopting values that outlast short-lived trends and movements – just like the stability of any building depends on a solid foundation. The Obere Schloss Castle, emblem of the town of Siegen, built in1259, is a good example of this.
