FST Industry

What FST Industry does

FST Industrie GmbH is a Berlin-based industrial manufacturer and engineering services provider that originated as a former 100% subsidiary of Siemens AG and became independent through a Management Buy Out on May 1, 2008. The company designs, manufactures, and commissions customized process plants — including absorption cooling systems, re-cooling units, vacuum and compressor units, and special process units — alongside high-voltage subassemblies for gas-insulated switchgears and transmission lines (GIS/GIL), piping systems, medium-voltage and railway circuit breakers, rotary piston flow meters with PTB custody-transfer approval, and electromechanical drives and components. Core competencies are built around specialized welding (notably orbital welding for aluminum and high-alloy steels), certified non-destructive testing per DIN EN 473, and full-scope project execution from engineering and CAD-based design through manufacturing, assembly, on-site commissioning, and logistics. Operational scale includes approximately 150 plants and thousands of components delivered annually worldwide, supported by roughly 12,100–18,000 m² of production and storage space in Berlin's Gartenfelder Straße industrial area, with 51–100 employees.

The company monetizes through project-based, quote-priced engagements with enterprise customers, combining professional services (engineering, project planning, construction, welding, NDT, assembly, commissioning, logistics) with hardware sales of components and subassemblies. Go-to-market is direct enterprise field sales targeting four customer segments: process engineering (chemical, pharmaceutical, steel, plastics), power transmission and distribution, rail and railway systems, and oil and basic materials industries. Named enterprise customers include Siemens AG (long-standing partnership anchored in the former-parent relationship) and Framatome GmbH for nuclear-grade work. The firm is privately held under Executive Director Frank Hermann, with wholly-owned subsidiaries Leffek Industrie GmbH (Duisburg, automation and container solutions) and Wilgen Korrosionsschutz GmbH (Ahrensfelde, industrial coatings), and holds a dense stack of certifications including DIN EN ISO 9001:2015, ISO 14001:2015, ISO 3834, AD 2000 HP0, EN 1090-2/3 (up to EXC3), PED 2014/68/EU, and KTA 1401 / IAEA QM confirmation for nuclear applications.
