Broad incumbents

• Bilfinger: German-listed industrial services and construction group serving process industry, energy and infrastructure clients. Competes with Unger on large turnkey construction and EPC scopes, but at considerably larger scale and with a services-heavy model.
• Max Bögl: Large German construction group with significant steel construction, precast and infrastructure capabilities. Competes with Unger on complex DACH projects while operating a much broader portfolio (tunnels, wind towers, mobility).
• voestalpine Stahlbau: Austrian steel and technology conglomerate whose Stahlbau division supplies structural steel for industrial and infrastructure projects. Overlaps with Unger but competes at much larger scale and across a much wider product portfolio.

Direct peers

• SEH Engineering: Hannover-based steel and facade engineering firm delivering complex structural steel, facades and industrial buildings across Europe. Comparable to Unger in architectural-grade steel and project-based delivery.
• Zeman Group: Austrian-headquartered family-owned steel construction and hall-building group with similar turnkey structural steel capabilities across Central Europe and the Middle East. Directly comparable to Unger in product scope (steel fabrication, building shells), customer base, and multi-country operating model.
• Donges Group: German steel construction and bridge-building group operating in structural steel, bridge construction and industrial steelwork. Comparable to Unger in core product (heavy structural steel fabrication) and DACH market exposure.
• Stahlbau Nägele: German-Austrian steel fabricator active in bridge, structural and architectural steel construction. Overlaps with Unger in product offering and DACH customer base, though smaller in scale.
• Waagner-Biro: Vienna-based steel and stage engineering specialist with a long history of architecturally demanding steel projects worldwide. Overlaps with Unger's portfolio in complex structural steel, infrastructure and public/commercial builds.
• Haslinger Stahlbau: Austrian steel construction firm focused on structural steel engineering, fabrication and assembly for industrial and commercial buildings. Comparable to Unger in size, geography (Austria/Central Europe) and project types.
• MAGE: Salzburg-headquartered structural and architectural steel construction company serving industrial, commercial and infrastructure projects across Central Europe. Directly comparable regional competitor in steel fabrication and assembly.
