History
Innovation as tradition
From a small ironworks to one of the most modern foundries in Europe - in its 125-year history, COSWIG GUSS has constantly developed itself and the casting process.
COSWIG GUSS has been merging traditional craftsmanship and modern technologies since 1892. With passion, experience and a spirit of research, we have pushed the boundaries of what is possible, mastered new challenges and won over new customers. Our high standards and our demanding customers are constantly driving us forward. Today, we produce and develop customized castings in our high-performance plant. We are one of the leading international suppliers in the manufacture of rolls and special components for wind turbines, industrial mills and printing machines.
But we are not resting on our laurels. We grow with our tasks. Then as now, COSWIG GUSS continues to research innovative concepts to make our products, processes and materials that little bit better. Join us on this journey into the future.
