SERINDUS Group

What SERINDUS Group does

SERINDUS Group is a family-owned industrial services group founded in 1964 and headquartered in Haguenau, in the Grand Est region of France. The group federates twelve wholly-owned subsidiaries that collectively deliver integrated industrial services spanning electrical engineering (HT/BT transformer stations, industrial and tertiary cabling), industrial automation (PLC programming, SCADA supervision using WINCC and Intouch, robotics, industrial networks), mechanical engineering (machining, locksmithing, regulation and safety valves), climate engineering (HVAC, industrial and commercial refrigeration), and specialized machine manufacturing (industrial furnaces, test benches, process equipment, hydroelectric turbines). The group employs 350 people and reports €40 million in annual revenue.

The group serves enterprise clients in chemical, petrochemical, pharmaceutical, food processing, aerospace, automotive, textile, paper, hydroelectric power, and renewable energy sectors, with additional tertiary sector work in hospitals, performance venues, and public infrastructure. Service delivery is field-based across Alsace, Lorraine, Champagne, and cross-border into Germany, Switzerland, and Luxembourg. Revenue is generated through three primary streams: industrial maintenance contracts (preventive and corrective, available 24/7/365), new construction and installation work (from design studies to commissioning), and specialized machine manufacturing. Pricing is quote-based with no public disclosure.

The group is led through a federated subsidiary model where each entity operates with a technical specialty (SIMEC for electrical, SASI for engineering studies, ERAT for the German market, SILMAT for industrial computing, SETIA for industrial processes, OBTEL for building automation, TILCO for sheet metal, PROCESS-ING for thermal treatments, Rhin Énergies for HVAC, ER3I for hydroelectric equipment, RICOM for industrial electricity). SERINDUS acts as master contractor for turnkey projects, with subsidiaries intervening by specialty at any project stage. The group has no external institutional ownership, no public listing, and no disclosed funding rounds.

Expansion highlights5 records

Broad incumbents

• Eiffage Énergie Systèmes: Eiffage group's energy and electrical systems division delivering industrial maintenance, electrical installations, automation, and climate engineering. Comparable across most of SERINDUS's service lines but at substantially larger scale and broader national coverage.
• Vinci Energies: Broad multi-technical services platform within the Vinci group, encompassing Cegelec, Actemium, Omexom, and other specialist brands. Operates across electrical, automation, HVAC, and industrial IT with far broader geographic and segment reach than SERINDUS.
• Equans: Multi-technical services group (spun out of Bouygues and recently acquired by Bouygues/SPIE combination) covering electrical, HVAC, automation, and industrial facility services across Europe. Direct overlap with SERINDUS across nearly all disciplines at much greater scale.

Direct peers

• SNEF: French family-owned industrial and electrical services group with multi-disciplinary coverage similar to SERINDUS, including industrial automation, maintenance, and new construction. Closest comparable by ownership profile (family group), service mix, and regional French footprint.
• Actemium: Vinci Energies' industrial-solutions brand focused on automation, process control, and digital solutions for industrial customers. Closely comparable to SILMAT/SERINDUS's automation and connected-factory offering.
• SPIE SA: France-headquartered multi-technical services group providing electrical, mechanical, and industrial maintenance across Europe. Direct competitor to SERINDUS in industrial services, automation, and facility management, but operating at vastly larger scale (~€8B+ revenue).
• Cegelec: Vinci Energies subsidiary specializing in electrical engineering, HVAC, automation, and industrial maintenance for energy, infrastructure, and industrial clients. Direct competitor in turnkey industrial projects and 24/7 maintenance contracts.

Emerging players

• Leadec: Stuttgart-headquartered industrial services specialist (formerly Voith Industrial Services) covering technical facility management, automation, and production-related maintenance for automotive and industrial customers. Closely comparable to SERINDUS's industrial-maintenance and automation business, particularly in Germany.

Regional players

• WISAG: Large German family-owned industrial and facility services group offering technical building services, industrial maintenance, and automation. Comparable to SERINDUS in ownership profile and German industrial-services focus, with presence in cross-border Rhine-region industrial accounts.
• Burkhalter Group: Swiss listed multi-technical services group delivering electrical engineering, automation, and maintenance to industrial and commercial clients. Highly comparable business model to SERINDUS but operating primarily in Switzerland rather than France/Germany.
