Salzgitter AG’s New Hot Straightening Machine Now Operational
09/03/2026 - Salzgitter AG’s subsidiary, Salzgitter Mannesmann Grobblech GmbH, announced its new hot straightening machine is now operational at its plant in Mülheim an der Ruhr, Germany.
The company said the plant is expanding its capabilities in sheet metal processing and improving its access to new applications and markets, focusing on the energy infrastructure sector. The machine was developed in collaboration with Buma Engineering & Anlagenbau GmbH to special and specific specifications to enable production of thick sheets with high strength.
“Thanks to our investment in the hot straightening machine, we — as specialists in heavy plate — are able to further expand our expertise in the infrastructure sector for the future market of wind energy,” said Hans-Jaan Rachner, managing director of technology and finance at Salzgitter Mannesmann Grobblech GmbH.
Tens of millions were invested to dismantle the company’s old machine and install a new system. Special tracks were installed over the cooling beds to allow for the foundation to be put down and the installation of the new system while demolishing the old one. Only a brief shutdown was required for dismantling, installation and commissioning, the company said.
“This will improve our competitiveness and position us to further tap into future markets,” said Gunnar Groebler, chairman of the executive board of Salzgitter AG.
