Rudolstädter Systembau

What Rudolstädter Systembau does

Rudolstädter Systembau GmbH (RSB) is a family-owned German construction services company headquartered in Rudolstadt, Thuringia, with a secondary office in Höchberg, Bavaria. Founded over a century ago, the firm operates as a general contractor (Generalunternehmer) delivering commercial construction projects from planning through turnkey handover. Its core technical capabilities span steel construction and fabrication, metalwork, custom facade engineering (including complex architectural geometries such as Daniel Libeskind's Jewish Museum Berlin extension), solar/EV charging infrastructure integration, and turnkey commercial building delivery. The company uses LEAN management methodology and has achieved DGNB Gold certification on the VIMA Erding project in 2025.

RSB's revenue model is project-based B2B contracting — fixed-price or open-book arrangements with milestone payments (30% on order, 60% at fabrication start, 90% at completion, balance on acceptance) per its AGB. The firm sells through direct enterprise sales, industry events, referrals, and repeat business, targeting enterprise and mid-market buyers across four primary verticals: fuel retail and mobility infrastructure operators (Shell, Aral/BP, JET, E.ON), commercial real estate and hospitality (McDonald's, Maritim Hotel, VIMA), public sector and institutional clients (Stadt Arnstadt, Jüdisches Museum Berlin, universities), and industrial/manufacturing (Melexis, Interroll, Walter AG). Geographic reach is primarily German with international projects in Norway and Sweden.

The company is managed by three Geschäftsführer (Gunther Batzke, Christian Franke, Simon Weilnhammer), with Simon Weilnhammer identified as managing shareholder (geschäftsführender Gesellschafter). RSB differentiates through vertically integrated delivery under one roof, century-long heritage credentials, and a growing pivot toward EV charging infrastructure (including Aral Pulse and E.ON T-Pole co-development), positioning it for the energy transition of the mobility sector.
