What Zublin Stahlbau does
Züblin Stahlbau GmbH is a German steel construction company operating as the Direktion Stahlbau division within Ed. Züblin AG, itself part of the STRABAG SE group. Founded as part of the Züblin construction heritage dating to 1898, the company is headquartered in Hosena with production facilities in Sande and Dinklage and additional offices in Dresden and Berlin. It specializes in four integrated service lines: steel high-rise construction (Stahlhochbau), steel bridge construction (Stahlbrückenbau), facade construction (Fassadenbau), and plant and apparatus construction (Anlagen- und Apparatebau). The company delivers projects from a single source — covering design, structural calculation, 3D modeling using industry CAD/CAM solutions, fabrication, and on-site assembly.
The business operates with significant capital intensity, maintaining up to 20,000 tons of annual fabrication capacity and the ability to produce individual components weighing up to 120 tons. It employed 518 qualified staff across three production locations in 2025 and generated €145 million in revenue. Recent marquee projects include the Stuttgart 21 deep railway station (2012-2026) for DB Projekt Stuttgart-Ulm GmbH, the Amager Bakke waste-to-energy plant in Copenhagen (2015-2017), the Talbrücke Schorgast (2018-2020), and the Hertha-Peters-Brücke replacement in Peine (2023).
The go-to-market is enterprise field sales targeting large infrastructure and industrial construction projects, acquired through competitive public and private bidding. Customer concentration is heavily skewed toward government and municipal clients — federal construction authorities, Deutsche Bahn subsidiaries, and municipal governments — with project delivery extending across Germany and selected European markets including Denmark, Finland, and France. Züblin Stahlbau GmbH is a wholly-owned subsidiary of Ed. Züblin AG, which is controlled by STRABAG SE (publicly listed on the Vienna Stock Exchange), meaning the steel construction division is integrated within a much larger corporate structure rather than operating as an independent entity.
