LOCATIONS

MARIENBORN PLANT

At our Marienborn plant, we cast specialty iron and steel materials into rolling mill rolls for the steel and aluminum industries, as well as nuclear cask containers for the disposal of highly radioactive spent fuel elements from nuclear power plants.

HAIN PLANT

At the Hain plant, we produce semi-finished and finished components for the machine building industry machine construction using four different casting processes for our specialty cast iron grades. In addition, nuclear cask containers for the disposal of low to medium radioactivity and high-radioactivity nuclear waste are produced at the Hain plant.
