ThyssenKrupp AG is one of the largest technology companies in the world. The Business Area Steel Europe is one of the world’s leading suppliers of carbon steel flat products. With around 27,000 employees and highly efficient facilities, the company produces around over 13 million tons of crude steel per year – making it Germany’s largest flat steel manufacturer. The Duisburg mill is the heart of the company. Its location on the Rhine has been invaluable ever since the site was founded in 1891: Downstream processing operations are performed in Bochum, Dortmund, and the Siegerland area on state-of-the-art rolling and coating lines.
