What Blechtechnik Koller GmbH does

Blechtechnik Koller GmbH is a family-owned contract sheet metal manufacturer based in Graz, Styria, Austria, with origins dating to 1884. The company operates a single-site production facility with approximately 40 employees, serving industrial and commercial customers primarily within the Styria region. Its core service is contract manufacturing (Lohnfertigung), producing sheet metal components ranging from simple rectangular cuts to complex fabricated assemblies, with capabilities extending into artistic metalwork inherited from its founding as a Bau- und Kunstschlosserei.

The company operates a fleet of modern CNC-controlled machinery including Trumpf TruLaser flatbed laser systems (5,000–6,000 Watt), Hämmerle (200-ton) and Beyeler (500-ton) press brakes, a Beyeler CNC shear, TimeSavers Grindingmaster deburring/finishing equipment, and Haeger press-in fastening systems. Services span laser cutting, CNC forming, certified welding (TIG/MAG/filler wire under IWT/IWS supervision), deburring, and final assembly. The business holds ISO 9001:2015, ÖNORM EN 1090 (structural steel/aluminum), ÖNORM EN ISO 3834-2 (fusion welding quality), and EN 15085-2 (railway welding) certifications, qualifying it for structural and rail-vehicle component supply. Supplementary services in mechanical processing and surface treatment are delivered via partner companies.

The revenue model is project-based contract manufacturing: customers submit specifications via the company website or phone and receive quotations, after which Blechtechnik Koller fabricates and ships finished or semi-finished components. Pricing is not publicly disclosed. Distribution is direct B2B sales to manufacturing industry and trade customers in Styria, with the company's stated philosophy being 'Der Kunde ist Partner' (The customer is partner). The business has been family-managed since the Koller family acquisition in 1992, currently under Managing Directors Andreas Koller and Jürgen Koller (MSc.), with Ewald Wolf as Prokurist. No external institutional investors, funding rounds, or M&A activity are referenced in the source material.
