Salzgitter builds a new hot straightener for the future wind energy market

Salzgitter Mannesmann Grobblech is building a new hot straightening machine at its Mülheim an der Ruhr site in one of the largest single investments to date. This investment will expand sheet metal processing capabilities and improve access to new applications and markets, particularly in the energy infrastructure area. It is scheduled to go into operation from summer 2026.

The Austrian company Buma Engineering & Anlagenbau GmbH was selected as the partner for the construction of the hot straightener. This investment will expand sheet metal processing capabilities and improve access to new applications and markets, particularly in the energy infrastructure area. The new hot straightening machine is scheduled for commissioning in the summer of 2026 and will enable the production of particularly thick sheets for energy infrastructure applications such as offshore foundation structures. In addition, the sheet metal logistics have been newly optimized so that sheets up to 24 meters long will already be available for the construction of wind towers as from this summer. The first project for a renowned wind tower manufacturer has already been booked.
Gunnar Groebler, Chairman of the Executive Board of Salzgitter AG, commented as follows: "The energy transition cannot succeed without high-performance steel products. The expansion of the entire energy infrastructure comprising the generation, transmission and storage requires steel. With its heavy plate specialists Ilsenburger Grobblech and Salzgitter Mannesmann Grobblech, the Salzgitter Group ranks as a full-range supplier in the wind sector. The investment in the hot straightener is further proof that we are continuously investing in our business activities in order to maintain our competitive strengths and open up future markets."
Hans-Jaan Rachner, Managing Director Technology Salzgitter Mannesmann Grobblech GmbH: "The special feature of this order for the expansion of renewable energy is that the wind towers are made from CO2-reduced slabs from electric steel production and thereby represent a further visible sign of sustainability at our company. Thanks to this investment, we at Salzgitter Mannesmann Grobblech will be able to establish a further foothold in the wind sector and thereby open up avenues for convincing new customers of our high-quality products."
