Producing hot-rolled special profiles in customized geometries and steel grades is our core competence. These products save you time and money, because no further processing and finishing is needed. Our made-to-order shapes and custom steel properties also reduce the weight of your end products.They improve dimensional accuracy in general and enhance the mechanical properties of the components they are used in. Last but not least, our special profiles provide surfaces that meet the most exacting quality requirements.
Welcome to Mannstaedt GmbH!
We are a world leader in hot-rolled steel special profiles. Our expertise is born from decades of experience in many fields: engineering, metallurgy, roll design, hot rolling and further processing. Our steel profiles make the impossible possible.Plan your journey

Steel moulded to your individual needs
Special steel profiles
Developing solutions for any requirement
We always meet our customers’ requirements, whether they are looking for special material properties or have particular expectations in terms of straightness, drilling, surface quality, or the lengths of their bars or pieces. No other manufacturer of special profiles can rival the variety of products and materials we offer.
Committed to more than just steel
Taking responsibility – not just for ourselves, but also for others – is one of our top priorities. This attitude shapes the way we think and everything we do. Preserving the environment and climate as well as protecting our staff and the people around us are key concerns for us as a company. That’s why we follow standards that go above and beyond our certifications.
Our production plants
Cutting-edge rolling mills for a great variety of profiles
Our rolling mills with a capacity of 200,000 tonnes enable us to manufacture profiles to suit virtually any requirement and area of application. We produce special profiles with weights of 2 kg/m to 180 kg/m, thicknesses of 2 to 6 mm and bar lengths of up to 24 metres.
Our rolling mills:
- Product range: 15 – 180 kg/m
- Max. width: 400 mm
- Min. thickness: 6 mm
- Bar length: Up to 24,000 mm
- Product range: 2 – 35 kg/m
- Max. width: 180 mm
- Min. thickness: 2 mm
- Bar length: Up to 18,000 mm"
Our development centre – Always one step ahead
We are consistently optimising our profiles and developing them further. Engineers, materials experts, technicians, designers, lab staff and other specialists work hand in hand to develop tomorrow’s solutions today. Our fully equipped lab tests geometries, material properties and surfaces in order to make our steel even better than it already is. We also invest judiciously in our production plants to ensure that we can keep developing our pioneering ideas for many years to come.
Further processing that meets highest standards
When it comes to dimensions, tolerances, materials and surface properties, Mannstaedt’s production team is constantly extending the limits of what is possible. Just like the other areas of our business, our further processing services produce results that comply precisely with our customers’ requirements. No matter what the customer expects, we always find the best possible result – together. In addition to hot rolling, we also offer a range of other processing steps: drawing, welding, sawing to size, blasting, milling and coating.
Here at Mannstaedt, all our production sequences follow reliable processes and comply with all the relevant international standards: DIN EN ISO 9001, DIN EN ISO 14001, DIN ISO/TS 16949 and DIN EN ISO 50001.
Our production process
A real future – our history
Johann Wilhelm Windgassen buys the plot of land that has remained the company premises until today and founds Windgassen Friedrich-Wilhelms-Hütte.
Entrepreneur Louis Mannstaedt takes over the Façoneisen rolling mill and founds Louis-Mannstaedt & Cie. AG.
The company is bought by the Klöckner corporation. At that time, already around 4,000 people work at the mill.
Ownership of the company changes hands several times. In 1986, the company becomes part of Klöckner Stahl GmbH. British Steel plc. takes it over in 1990.
The plant returns to German ownership, in the form of Georgsmarienhütte Holding.
