Bar products

In our warehouse, we strive to have the most common steel qualities universally available to guarantee the shortest possible delivery times. We can deliver rough forged, peeled, or turned bar steel depending on the customer's requirements. The bar material can be sawed into discs with very tight tolerances. We have a well-equipped machine park available for this purpose.
In association with our partner companies, we can also manufacture semi-finished products such as forging dies or hollowed bars.
