In order to guarantee shortest delivery time, we are keen to keep the respective steel goods, wherever possible, universally available in our warehouse. According to customers requirements, steel bars can be delivered rough forged or premachined. The bar material can be sawed into discs of closest tolerances, for example. A well-equipped plant for sawing; peeling- and turning operations is available for this. Semi-finished tools, such as forging-dies or hollow-drilled bars, can also be manufactured in cooperation with subcontractors.
