Bright steel production with high dimensional accuracy and a clean surface
Take advantage of our decades of experience and the continuous development of our bright steel technologies and plant engineering to create the best possible conditions for meeting demanding customer requirements.
Bright steel is used wherever the highest standards of dimensional accuracy, surface quality, straightness and material properties are required. The mechanical machining of rolled steel produces products with precise dimensions, improved surfaces and defined properties for further processing. This enables downstream machining steps to be reduced, manufacturing processes to be optimised and the quality of the end products to be enhanced.
If your needs in terms of surface quality, freedom from defects and dimensional accuracy go beyond the possibilities of rolled steel, our bright steel is the right product for you. We are your partner of choice for applications that require combinations of heat treatment with close tolerances, precise bright steel production, the production of dimensionally accurate short sections, end machining and straight turning.
Our bright steel products are used across a wide range of industries – for example, in mechanical engineering, the automotive industry, linear technology, drive technology and safety-critical components. The combination of our own steel base, state-of-the-art manufacturing technology and comprehensive quality testing enables us to produce bright steel with reproducible properties and a high degree of process reliability.
In addition to tight dimensional tolerances, our customers benefit from technically flawless surfaces, high material quality and reliable delivery performance. In this way, we lay the foundations for cost-effective manufacturing processes and high-quality end products.

Peeling and burnishing for the best surface quality and straightness
We produce new bar surfaces free from technical defects, scale and surface decarburisation through the mechanical processing of rolled products with peeling using hard metal indexable inserts.
Subsequent burnishing with convex and concave rollers improves the straightness of the bars and produces lower roughness values. Talk to us if your bright steel requirements go beyond the properties according to the EN 10277 standard.
Further information about our range of services is available here.
Non-destructive inline testing for the highest reliability
We use highly modern testing lines to monitor the quality of our bright steel production. This includes verifying the surface quality, freedom from internal and near-surface defects and the identity of the material. Crack testing and material identification are based on the eddy current method, testing for internal defects is based on ultrasound.
Even more accurate with grinding
We produce the tightest tolerances of our bright steel products on our centreless cylindrical grinding machines. Tolerances up to < h6 are possible on the ground bar. Our grinding technology perfectly complements our surface hardening facilities. Shafts for linear technology applications are therefore part of our product portfolio.
Frequently asked questions about bright steel production
What is bright steel?
Bright steel is mechanically machined bar steel with high dimensional accuracy, improved surface quality and defined material properties. It is used when requirements exceed the capabilities of rolled steel.
What advantages does bright steel offer over rolled steel?
Bright steel is characterised by tighter tolerances, greater straightness, scale-free surfaces and improved processability. This allows manufacturing processes to be organised more efficiently.
For which applications is blank steel suitable?
Blank steel is used, amongst other things, for shafts, axles, guide elements, fasteners and other precision components in mechanical engineering, the automotive industry and linear technology.
How is the quality of blank steel ensured?
Quality is monitored using modern testing methods. These include eddy current testing to detect surface defects and ultrasonic testing to check for internal material defects.
