Stern Metallbau

What Stern Metallbau does

Stern Metallbau GmbH is a privately held, owner-managed (inhabergeführte) German Mittelstand metal-fabrication company headquartered in Burtenbach, Bavaria, with a secondary production site (Werk 2) in Münsterhausen. Founded in 2007, the company operates from ~20,000 m² of production area with approximately 70 employees and delivers end-to-end subcontract manufacturing services covering sheet-metal processing (Trumpf fiber-laser cutting, tube-laser cutting, CNC bending, punching), certified welding including Yaskawa robotic welding cells, CNC milling/turning (DMG Mori, Deckel-Maho, Hyundai, Alzmetall), surface finishing (grinding, vibratory finishing), and in-house powder coating on a Gema automated line with 5-zone pre-treatment.

The company serves industrial OEMs across Germany, with public reference logos including Liebherr (construction machinery), AGCO (agricultural machinery), Kögel (commercial vehicles/trailers), Goldhofer (heavy-duty transport), Wanzl (retail equipment), AL-KO (chassis technology), Kränzle (cleaning equipment), and Eurotec (fastening technology). Its quality system is certified to ISO 9001:2015 (2023), DIN EN ISO 3834-2 and EN 1090-2 (2015), with EN 1090-1 (2024-2027) and International Institute of Welding membership.

Stern Metallbau operates a quote-based, project-driven B2B revenue model with no published pricing; customers request quotations via contact form, dedicated sales/purchasing/HR email channels, or telephone. Distribution is exclusively direct from its two German facilities with no resellers, marketplaces, or e-commerce. Revenue derives from contract metal-fabrication project work and fee-for-service powder coating (including a 24-hour express option), with turnover per job generally one-time and non-recurring. Customer acquisition relies on the corporate website, organic social channels (Facebook, Instagram, YouTube), and a Partner page listing named industrial relationships.

Core offering

Stern Metallbau GmbH is a contract metal fabricator producing complex metal constructions, sub-assemblies, single parts, small and large series, and special constructions in steel, stainless steel and aluminum. Services cover the full process chain — laser and tube-laser cutting, CNC bending, certified welding including robotic welding, CNC milling/turning, surface grinding, vibratory finishing, and powder coating — primarily for industrial OEM customers in Germany.

Product overview

Stern Metallbau GmbH operates a single integrated metal-fabrication business organized as a platform of in-house manufacturing service modules rather than discrete packaged products. The core platform is Metal Construction (Metallbau), which spans sheet metal processing, CNC machining, and surface treatment; that platform is delivered through the individual service modules Technologie, Laser-/Rohrlaserschneiden, Abkanten, Schweißen, Schleifen, Gleitschleiftechnik, CNC Zerspanung, Pulverbeschichtung, and Qualitätsmanagement — all underpinned by the company's machinery fleet (Trumpf, SafanDarley, DMG Mori, Deckel-Maho, HYUNDAI, Alzmetall, Gema, Yaskawa) and its quality certifications (DIN EN ISO 9001:2015, DIN EN ISO 3834-2, EN 1090-1, EN 1090-2). The 2023-added Montagebereich (assembly area) and 2024-commissioned Yaskawa welding robot system extend the offering into assembly and automated welding.

Expansion highlights4 records

Emerging players

• Laserhub GmbH: Digital platform for on-demand sheet-metal parts sourcing that aggregates European fabrication capacity — emerging player competing for the same industrial buyer wallet by offering instant online quoting versus Stern's manual, hours-bound inbound model.

Direct peers

• August Mössner GmbH + Co. KG: German metal components manufacturer producing complex precision parts and assemblies for industrial customers — directly comparable in scope (cutting, forming, machining) and Mittelstand positioning.
• Alois Müller GmbH: German Mittelstand metal fabrication and precision parts manufacturer based in Balingen, offering laser cutting, CNC bending, welding, machining and surface finishing — directly comparable in service scope, customer base (industrial OEMs) and Mittelstand ownership profile.
• Heinrich Wörner GmbH: German contract metal fabricator offering laser cutting, CNC bending, welding and powder coating to industrial customers — closely matching Stern's value proposition of a one-stop sub-supplier for sheet metal and assemblies.
• Konrad GmbH: German Mittelstand metal parts manufacturer serving industrial OEMs with cutting, forming and assembly — comparable business model focused on complex fabricated components for industrial customers.
• Dunkel GmbH: South German contract manufacturer of metal components and assemblies for industrial OEMs — directly comparable Mittelstand metal fabricator with similar customer-type focus.

Regional players

• voestalpine AG: Austrian-based steel producer and metal-processing group with significant fabrication and component operations serving European industrial OEMs — comparable end-customer industries (commercial vehicles, construction, rail) but operating primarily in Austria/DACH-adjacent rather than competing directly within southern Germany.

Broad incumbents

• Trumpf SE + Co. KG: Global leader in laser cutting and bending equipment — Stern is a customer of Trumpf machinery — and operator of its own fabrication service business, putting it in adjacent/overlapping territory as a much larger, equipment-led player in the same technology stack.
• Bystronic Laser AG: Global manufacturer of laser cutting and bending systems with an adjacent service business — operates in the same sheet-metal fabrication space but as a much larger, equipment-led incumbent rather than a Mittelstand contract fabricator.
• Schuler Group: Global press technology and metal-forming equipment provider — broad incumbent in the metal-fabrication technology value chain that serves similar industrial OEMs with forming solutions.
