Thanks to the enlargement of our production from manufacturing only rings and flanges in mechanical subcontracting, we have in recent years been able to advance into a new important business segment. In addition to machining based on drawings, we also offer our expertise to support our customers, right from the engineering stage, thus helping them to make their production more efficient. This service and our partnership working guarantees a precise and efficient high-quality-product at all production stages. This was confirmed when the first European patent for a flange system with corrosion preventive design was granted.

The highest possible product quality and excellent service are two key factors, not just in our area, which ensur that we can compete today and  be ready for tomorrow. Our customers are active in the field of wind energy, tank and apparatus construction, mechanical engineering and thermo processing. Fifty employees at our headquarters in Siegen (Germany) and a steadily growing global network of sales agents work every day to perfect customer satisfaction.

Our steadily growing customer base demonstrates that we are on the right path with this strategy. Siegthaler stands for quality, service and reliability – now and into the future.
