High-quality semi-finished products made from precision steel
Precision from the first step to the ready-to-install component
As a strong solution partner and manufacturer, we have been supplying high-quality semi-finished products made of precision steel for demanding key industries since 1904. We see precision not only as a requirement, but as the foundation on which your products and machines function reliably.
Our precision steel semi-finished products are pre-machined raw materials that impress with their precise machining, tight tolerances, and guaranteed material quality. Thanks to their maximum dimensional accuracy, you can process them directly. This shortens your throughput times and increases efficiency in your production.

To the shop
Precision flat steel
Precision flat steel forms the basis for many tools and machine parts. We supply flat steel in accordance with DIN 59350 with a scale-free surface and in an annealed condition. Thanks to our manufacturing process with tight tolerances in terms of dimensional accuracy, flatness parallelism, our flat steel can often be processed directly.
Precision square steel
Our precision square steel is also manufactured in accordance with DIN 59350 and is ideal for the construction of frame structures and other solid components. We guarantee dimensional accuracy in width, thickness, and length, as well as excellent angularity and parallelism. On request, we can supply with machining allowance as a custom-fit cut.
Precision round steel
We offer precision round steel as the perfect solution for rotating parts, shafts, and cylinders. The ground version with tight tolerances (e.g., h8) is ideal for applications in molding tools, machine parts, and structural elements. We carry a wide range of heat-treated and non-heat-treated tool steels.
Precision eroding blocks
Our precision erosion blocks are the first choice for the demanding manufacture of tools for erosion and countersinking. We supply them in common materials such as cold work steel 1.2379 with a scale-free end face. They are available both soft annealed hardened (e.g., 61 +/- 2 HRC) with the grain running perpendicular to the contact surface.
Precision steel plates
Our precision steel plates are the reliable basis for the construction of base frames, mountings, and other solid elements. We offer customized dimensions and maximum flatness for your demanding applications.
