Schlosserei Metallbau

What Schlosserei Metallbau does

Ludwig ZEHETMAIR Metallbau & Stahlbau, operating commercially as Schlosserei Metallbau, is a sole-proprietorship metalworking and steel construction firm headquartered in Raubling, Bavaria, Germany. The company manufactures custom steel, stainless-steel, and aluminum fabrications for industrial/commercial, private/residential, and municipal/government clients across the Rosenheim–Munich–Voralpenland corridor. Its product portfolio spans metal and steel construction, balconies, railings, doors, gates, facades, roofing, steel halls, stairs and emergency stairs, complemented by surface finishing and transport/montage services.

The firm holds DIN EN 1090 EXC2 certification, which qualifies it to execute structural steel and aluminum projects for commercial and public-sector clients — a regulatory threshold that excludes many smaller uncertified competitors. Operations are conducted through a workshop-based production model using conventional metalworking equipment, supplemented by a partner network (e.g., laser-cutting and assembly providers) that extends capability without proportional capex. The technical model is execution-led rather than platform-led: each project is custom-engineered to client specification rather than produced from a standardized catalog.

Revenue is generated through direct, quote-based sales on a project basis, with pricing determined by material, complexity, certification requirements, and site-specific conditions. Headcount is reported at approximately 57 employees (firmographic data), though one secondary source cites 2–3; this discrepancy remains unresolved. The firm operates without external funding, acquisitions, or digital-platform scaling signals typical of venture-backed operators, reflecting a traditional Mittelstand-style regional business model.

Direct peers

• Kleusberg GmbH & Co. KG: Kleusberg is a German family-owned manufacturer of modular steel buildings and steel halls for commercial, educational, and industrial clients. Comparable as a German steel-building fabricator with similar DIN EN 1090-certified execution and end-market overlap in commercial/industrial hall construction.
• Astron Buildings: Astron is a Luxembourg-based manufacturer of prefabricated steel buildings and hall systems serving commercial and industrial customers across Europe. Directly comparable because both deliver engineered, prefabricated steel hall solutions to industrial and commercial buyers, though Astron operates at a far larger, standardized-product scale versus Zehetmair's bespoke project model.
• Zeman Group: Zeman is an Austrian-headquartered steel construction and hall-building specialist serving industrial and commercial clients across the DACH region. Comparable as a DACH-based fabricated structural steel and steel hall provider with similar project-based go-to-market targeting industrial/commercial end markets.
• ALHO Group: ALHO is a German manufacturer of modular and prefabricated steel buildings for commercial, public, and industrial use. Comparable because both produce engineered steel building systems (halls, modular structures) and operate in the German market, though ALHO operates at much greater scale with standardized modular product lines.
• Haslinger Stahlbau: Haslinger is an Austrian steel construction and engineering company producing structural steelwork and steel halls for industrial and infrastructure clients. Comparable as a DACH-region fabricated structural steel peer with similar hall-construction focus, though Haslinger is significantly larger and serves wider infrastructure/bridge markets.
• Butzkies Stahlbau: Butzkies is a German steel construction company producing steel halls and structural steelwork for commercial and industrial customers in the DACH market. Comparable as a similarly-sized regional German steel fabricator executing project-based structural and hall work with comparable DIN EN 1090 execution-class positioning.
• WIBA Stahl- und Industriebau: WIBA is a mid-sized German steel hall and industrial building construction company with comparable regional DACH presence and project-based delivery model. Comparable because both execute custom industrial/commercial steel hall projects as mid-market regional fabricators rather than standardized product players.

Broad incumbents

• Donges SteelTec: Donges SteelTec is a major German steel construction and engineering firm executing large-scale steel bridges, halls, and industrial structures. Comparable as a much larger German fabricated structural metal incumbent competing in the same steel hall and structural markets, but at a national/international scale with bridge and infrastructure capabilities beyond Zehetmair's scope.
• Maurer SE: Maurer is a German engineering-led steel construction and structural protection systems company serving infrastructure and building clients across Europe. Comparable as a German fabricated structural metal incumbent with broader infrastructure/bridge portfolio that competes for some of the same structural and hall work in DACH.

Regional players

• Metallbau Mayer (regional Bavarian fabricator archetype): A representative regional Bavarian/DACH metalwork and steel-construction craft shop offering bespoke railings, balconies, doors, and small steel structures to private and commercial clients. Comparable as a same-size regional peer competing for similar residential and small commercial metalwork orders in the same Bavarian market.
