For the Franz Steger Transformatorenbau GmbH quality, on-time delivery and customer satisfaction are of highest priority - since years. As a owner-operated familiy business with complete equity financing we have the possibility to focus on the most important: our customers.

Our certifications from external partners and customers speak for themselves.
