DFA Industrial Assembly

What DFA Industrial Assembly does

DFA Industriemontage GmbH is a German industrial assembly services firm headquartered in Meerane, Saxony, founded in 1995 as a successor to assembly entities tied to the former SDAG Wismut mining concern and DFA Fertigungs- und Anlagenbau GmbH Chemnitz. The company delivers heavy-lift erection, maintenance, and refurbishment services for wind turbines, industrial steel structures, bridges, power plants, and mining equipment. It operates its own specialized crane fleet — telescopic cranes from 40t to 450t, crawler cranes from 250t to 1,600t, and tower cranes — that underwrites its capacity to execute large-scale industrial lifts without external rental dependency.

The company is structured around two divisions: a wind energy erection and maintenance unit (~80 employees) supporting Nordex, UKA, and Landwind across repowering and new-build projects in Germany and Western Europe, and an industrial steel and plant construction unit (~40 employees) serving steelmakers (Salzgitter Flachstahl, ThyssenKrupp Steel, Saarstahl, HKM), power generators (Kraftwerk Boxberg, Kraftwerk HH Moorburg), mining operators (MIBRAG), and infrastructure clients (DEGES). Operations are certified to ISO 9001:2015, ISO 14001:2015, EN 1090-2 execution class EXC3 for welded steel structures, and SCC** 2011 for contractor safety, health, and environmental management. Ancillary offerings include crane rental, welding services (MIG/MAG, submerged arc, stick electrode), expert inspection (Sachkundigenprüfung), and large component exchange for wind turbines.

Revenue is generated on a project-based professional services model: quote-driven, multi-year contracts with enterprise clients, delivered through direct B2B field sales. The company is privately held as a GmbH under German law, with Rosemarie Liedtke as sole managing director (Geschäftsführerin) and no disclosed institutional investors or funding rounds. Geographic reach spans Germany and Western Europe with additional project work in Austria and Sweden. Active engagements include the SALCOS low-CO2 direct reduction plant at Salzgitter (~9,000t steel scope, 68 DFA personnel on-site by mid-2025) and the Windpark Söllingen repowering (17 turbines, ongoing through April 2026).
