What STABAU does

STABAU GmbH founded on steel is a privately held German steel trading, rental, and buyback specialist serving civil engineering, special civil engineering, water engineering, canal construction, road construction, bridge construction, and harbor projects. Founded in 1995 in Dohna/Sachsen and restructured to its current business model in 1997, the company is headquartered in Röderland/OT Haida (Brandenburg) and operates regional sales offices in Germany (Wallenhorst, Olfen), Poland (Toruń), the United Kingdom (Bishops Stortford), France (Les Alluets-le-Roi), and Ukraine (Lviv), with a claimed delivery footprint of 47 countries across 4 continents.

The core product portfolio comprises warm-rolled sheet piles (Z- and U-Profiles with corner profiles), cold-rolled profiles (light profiles and trench sheets), steel tubes (spiral- and longitudinal-welded), steel beams (HEB/HEA/HEM wide-flange and U-beams), tie rod and wailing anchoring systems, sheets and plates, excavator mats, and special solutions (combined tubular sheet pile walls, box piles, beam wall systems). The company holds manufacturer qualifications (DIN 18800-7 Klasse E, EN 1090-EX 3, EN ISO 9001, DIN Fachbetrieb 103) and licenses the QsHeat Energiespundwand technology from Future Energy Technologies for thermally activated sheet pile walls used in geothermal heating/cooling. STABAU's wholly-owned subsidiaries STABAU Tiefbauservice GmbH and STABAU Verbau GmbH provide factory steel fabrication and excavation support systems respectively, while Hirnböck STABAU GmbH in Austria (minority stake, 2012) provides regional inventory.

The company operates a multi-channel revenue model combining (i) one-time sale of new steel manufactured to EN 10248 standards, (ii) sale of inspected quality-checked used steel (GREEN STEEL) with documented CO₂ savings equivalent to ~1,000 hectares of forest, (iii) usage-based rental of sheet piles, trench sheets, beams, and tubes with flexible terms and processing-on-return, (iv) professional services for factory steel construction (welding, custom fabrication, dolphin fabrication), and (v) buyback arrangements allowing customers to resell steel at project end. Pricing is quote-based and not publicly disclosed. Distribution is direct via enterprise field sales with project-specific consultation. The group is managed by Geschäftsführer Matthias Müller and Dirk Schöppner (Finance/Accounting/Controlling) and has approximately 87 total employees.
