What Trunz Group does
Trunz Group is a Swiss family-owned industrial manufacturer founded in 1972 by Remo Trunz, headquartered at the Trunz Technologie Center (TTC) in Steinach, Canton St. Gallen. The group operates through three wholly-owned business divisions under the holding entity Trunz Holding AG: Trunz Metalltechnik AG, which develops and produces complex metal assemblies from prototype to series production for vehicle construction, mechanical and plant engineering, and apparatus construction; Trunz Fahrzeugtechnik AG, which designs and produces lighting and system solutions for public passenger transport; and Trunz Water Systems, which develops, produces, and globally distributes solar-powered systems for decentralized drinking water and electricity supply. Supporting infrastructure includes approximately 10,000 m² of production space and 2,000 m² of office space at the TTC, with additional manufacturing operations in Arbon, Wittenbach, and Herisau, plus a Montenegro-based subsidiary (Trunz Montenegro d.o.o.) founded in 2020.
The company's go-to-market is direct B2B sales to industrial customers, with custom project-based pricing for assemblies and systems and no public price list. Distribution is conducted through direct engineering and procurement relationships with clients in vehicle construction, mechanical engineering, public transport, and (for Water Systems) international enterprise and development-sector buyers. Manufacturing capabilities include laser cutting, stamping, forming, and coating, supported by quality certifications (ISO 9001, IQNet, SVS) and ongoing investment including an 8,000 m² rooftop solar installation completed in 2023. The group employs 51-100 people and maintains a structured apprenticeship pipeline of 14 trainees across seven trades.
Ownership remains fully concentrated within the Trunz family. Effective January 1, 2024, Roger Trunz assumed operational leadership of the group, succeeding his father Remo Trunz who now serves as Chairman of the Board (Verwaltungsratspräsident). The company has historically used bolt-on acquisitions (Saurer 1991, NAW 2003, Metrohm 2010, Railtronic 2018) to add capabilities, divested Trunz Luftkanalsysteme AG in 2016 as part of succession portfolio rationalization, and partners with the EU Horizon 2020 REvivED Water consortium on solar desalination research.

Trunz Group competitors and assessment
Company assessmentDirect peers
- Feintool: Swiss-listed precision metal stamping and assembly manufacturer serving automotive and industrial customers. Closely comparable to Trunz Metalltechnik on geography (Switzerland), scale, and complex-assembly B2B manufacturing.
- Xylem: Global water technology company providing pumps, treatment, and decentralized water solutions. Direct comparability to Trunz Water Systems on the water-treatment end-market, though vastly larger and more globally distributed.
- Benteler International: Global automotive supplier of metal-formed components and assemblies (chassis, body, engine). Directly comparable to Trunz Metalltechnik's vehicle-construction and apparatus-manufacturing complex-assembly work, though at much larger scale.
- VAT Group: Swiss-listed manufacturer of high-end vacuum valves and related components for semiconductor and industrial customers. Comparable to Trunz Metalltechnik on Swiss precision-manufacturing roots and complex-assembly B2B model.
- Katadyn: Swiss-based manufacturer of portable and decentralized water filtration/purification systems for outdoor, humanitarian, and military markets. Closest geographic and product peer to Trunz Water Systems' solar-powered decentralized water supply offering.
- Mikron Group: Swiss precision manufacturer of machining solutions, components, and assemblies for automotive, medical, and writing instruments. Comparable in scale, Swiss-roots, and complex-assembly customer profile to Trunz Metalltechnik.
Broad incumbents
- Georg Fischer: Large Swiss industrial group with leading positions in metal processing (GF Casting Solutions) and flow systems. Operates as a much broader incumbent in adjacent metal/manufacturing categories to Trunz Metalltechnik.
- Hella (HELLA GmbH & Co. KGaA): Major automotive lighting and electronics supplier, now part of Forvia. Comparable to Trunz Fahrzeugtechnik on vehicle-lighting systems, though operating at vastly larger scale across broader automotive OEM customer base.
- Siemens Mobility: Global supplier of rail and public transport systems including rolling stock, signaling, and onboard systems. Overlaps with Trunz Fahrzeugtechnik's public passenger transport systems work, but at substantially larger scale and broader portfolio.
Regional players
- Stadler Rail: Swiss manufacturer of rail vehicles (locomotives, multiple units, tram-trains) and related systems. Comparable as a Swiss-headquartered player in the public passenger transport ecosystem served by Trunz Fahrzeugtechnik, though primarily a customer relationship rather than direct competitor.
