What Franz Dietrich does

Franz Dietrich GmbH is a German industrial services company founded in 1947 in Hannover, specializing in corrosion protection, structural protection, industrial paintwork, painting and decorating, and industrial floorings. The company serves industrial and commercial customers through project-based on-site services, employing more than 350 craftsmen, technicians, engineers, and commercial specialists distributed across eight German locations (Hannover headquarters plus regional offices in Sande, Niederlangen, Hofheim, Baunatal, Naunhof, Bad Dürrenberg, and Lehe) and supplementing domestic German operations with international projects in Europe, the Middle East, Asia, and Africa.

The company's technical core lies in surface preparation and coating systems compliant with DIN EN ISO 12944 and ZTV-ING standards, using environmentally sustainable blasting materials, filtration, and enclosed work areas. Differentiated capabilities include ESD coatings for automotive and electronics manufacturing, decontaminable coatings for nuclear facilities, anti-graffiti systems, structural concrete repair, and work performed under extreme conditions (heights, underwater, during active production). The company maintains ISO 9001:2015 and ISO 45001:2018 certifications, plus specialized credentials such as TRGS 519 for asbestos abatement, WHG §19 I specialist status, and sprayed-concrete DIN 18551 certification.

Revenue is generated through custom, project-quoted professional services contracts with enterprise and government clients, including Volkswagen, Audi, Daimler, Bugatti, Bosch, Continental, EADS, E.ON, Vattenfall, London Heathrow Airport, Wacker Chemie, and various road and water authorities. Pricing is per-project based on scope, surface area, complexity, and location, with multi-year contract cadence typical. The company is family-owned (currently Philipp and Frank Suppan, grandchildren of founder Franz Dietrich) with no disclosed external institutional investors, and operates as a private GmbH since reconverting from AG status in 2013.
