BROCKHAUS Stahl produces strip steel in its cold rolling mill at the Plettenberg site in South Westphalia, Germany. The BROCKHAUS Group has more than 160 years of industrial history. BROCKHAUS Stahl has been an integral part of this development for many decades and stands for long-standing experience in strip steel production.
BROCKHAUS Stahl produces:
in various grades, strength levels and surface finishes. The strips meet tight tolerances in thickness, width and flatness, and are designed for high formability and reproducible mechanical properties – with a strong focus on safety-relevant components.
Both product lines are designed for narrow tolerances and high process stability.
BROCKHAUS Stahl provides a broad range of materials for different requirements:
Microalloyed fine-grain steels
High strength combined with good formability
– e.g. HC180Y to HC500LA
High-strength microalloyed steels (BHS series)
Extreme formability combined with excellent wear resistance
– e.g. BHS 600 to BHS 1000
Carbon steels (C steels)
Suitable for customer-side heat treatment
– e.g. C22E to C60E
Case-hardening and quenched & tempered steels
High wear and fracture resistance
– e.g. 16MnCr5, 42CrMo4
Spring steels
Outstanding elasticity and fatigue strength
– e.g. C55S to 75Ni8
Cold strip with electromagnetic properties
Especially for relays, valves or stators
– e.g. BMS 90 and BMS 100
DC steels
Mild, highly formable steels
– e.g. DC01, DC03, DC04
Depending on the application, BROCKHAUS Stahl supplies grades with optimized formability, wear resistance or fatigue strength and supports customers in selecting the best-suited steel grade.
BROCKHAUS Stahl strips are used in many industries, including:
Mobility / automotive industry:
Components for chassis, driveline and safety; around 3 million vehicles per year are manufactured with components made from BROCKHAUS cold-rolled strip.
Coinage:
Proven core material for circulating coins.
Agricultural engineering:
Robust and wear-resistant components for agricultural machinery.
Other industries:
Mechanical engineering, defense applications, key manufacturing, high-performance springs and many other use cases requiring precise, high-strength strip steel.
BROCKHAUS Stahl is specialized in cold-rolled strips and offers:

Chemical and mechanical material testing
Yes. The application engineering team of BROCKHAUS Stahl supports customers from early concept phase through to series production, including:
The aim is to optimally balance weight, cost and performance of the component.
Typical steps:
BROCKHAUS Stahl is a reliable partner for:
Thanks to flexible production planning, pilot lots, ramp-up phases and long-term large-scale projects can be handled economically. The optimal batch size is defined together with the customer to balance material costs, setup times and logistics effort.
BROCKHAUS Stahl supports customers with flexible delivery concepts, such as:
Tailored packaging concepts, demand-driven lot sizes and efficient logistics processes ensure high material availability while reducing inventory and process costs.
On-time delivery is enabled by:
Depending on customer requirements, packaging can be provided vertically (eye to sky) or horizontally (eye to side).
Customers benefit from:
This helps to reduce scrap, unplanned downtime and tool wear. As part of the BROCKHAUS Group, BROCKHAUS Stahl can also offer integrated solutions for recycling, environmental technology and decarbonization.
BROCKHAUS Stahl relies on:
Mechanical properties, surfaces and dimensions are systematically tested to ensure reproducible quality, especially for safety-relevant components. In addition, the company adheres to common industrial and automotive standards and continuously improves its processes.
Sustainability is an integral part of the BROCKHAUS Group’s strategy. The Group has been climate-neutral since 2019 and fully offsets its CO₂ footprint. BROCKHAUS Stahl contributes by:
Yes. BROCKHAUS Stahl has been CO₂-neutral since 2019. Each delivery is carbon-accounted individually, and in-house emissions are fully offset.
