We are your dependable supplier of primary material, a producer of high-quality steel and a market leader in as-cast ingots and continuous-cast products in large dimensions. Above all, however, we supply our customers with steel in the form, for example, of cast ingots and continuous-cast formats that we precisely tailor to the requirements in their seamless tube and bar rolling mills, or for the rolling of rotating rail vehicle components. We are, in addition, a leading specialist in open-die forging, drop forging and seamless ring rolling.

Welcome to Stahlwerk Bous GmbH
Industry insiders know our mill as a byword for a broad range of products, made up of cast-ingot and continuous-cast formats and no less than 800 grades. Flexibility, top quality and our commitment to progress are what make us special. This is demonstrated by our wide range of steel compositions, our enormous variety of mould geometries, dependable delivery even at short notice, and our unceasing development of new alloys.

Steel exactly as you need it
The right format every time
Optimum quality
Our guiding principle is to find the best solution for our customers every time. We back up this target with an all-encompassing quality management system. Our ultra-modern facilities, combined with the skills and commitments of our employees, enable us to meet our customers' wishes down to the last tiny detail. And we will find new solutions in close cooperation with you, the customer.
Caring for the future
Where corporate responsibility is concerned, we set the same high standards as in our production and service: continuous improvement together. This is why we develop our facilities, processes and corporate culture ever further, in order to meet our many and diverse responsibilities both now and in the future.
Investing in the future
For more than 130 years, Stahlwerk Bous has been a trailblazer in all areas of steelmaking, from plant engineering up to and including solutions that have made the steelmaking process increasingly environmentally friendly. We introduced series production in seamless tube making, for example, and operate one of the world’s most advanced and efficient filter installations - two examples demonstrating that future-oriented investments are inseparably linked with the history of Stahlwerk Bous.
We melt crude steel of the utmost quality in our 70 tonne EBT-AC electric arc furnace and refine it in our secondary-metallurgy facilities to produce cast ingots and continuous-cast products of highest dimensional accuracy, all the while shielding the environment from harm with one of the world's most efficient extraction, filtration and dedusting systems.
