Siegthaler is a leading company in the production of flanges and rings. We started the bending and welding of rings production at the end of the 1930s. Our rings are used in fields such as wind power turbines, shipbuilding, tank and pipeline construction, mechanical engineering, industrial furnaces, autoclaves as well as tank and apparatus engineering.
At our site in Siegen, including our sales representatives active around the world, we are constantly working on achieving an even higher level of customer satisfaction. Thanks to the integration into a strong corporate structure in 1998, we can not only offer expertise in the the area of production, but also act as a system service provider. Our support starts with the design of our client’s products.Siegthaler equips onshore as well as offshore wind turbines, in Germany as well as internationally, with components. We are able to do so as we hold all the necessary approvals issued by certifying authorities. We can machine large components by turning, drilling and milling them and we are also capable of moving welded constructions up to a weight of around 50 t, while working with all commonly used materials.
