About Sirail
Groupe Sirail develops, produces and integrates complex electrical products and systems for leading European manufacturers. The portfolio includes cable harnesses and wiring at LV, MV and HV voltage levels (signal and distribution wiring, pre-assembled complex cable harnesses on mechanical carriers), electrical switchgear cabinets and enclosures, electrical modules as well as driver's cab solutions as plug-&-play or pre-assembled assemblies. The range of services extends from project management and design (circuit diagrams, 2D/3D drawings, work plans, test and qualification procedures) through industrialization and configuration management to prototype and series production. With six production sites in five countries — four European proximity sites (northern and southern France, Berlin, Follo) and two best-cost plants in Tunisia and Morocco — Sirail combines responsiveness with an optimized cost structure across a total of 34,000 m². The subsidiary Sirail Services offers on-site service: integration, maintenance, retrofit, diagnostics and repair of electrical and electromechanical systems, complemented by mechanical work, pipework and welding. Customer industries include rail, aerospace, industry, energy and defense.

Quality and Certifications
All sites are ISO 9001 and IRIS certified and have their own test benches for standard quality tests; first article inspection (FAI) precedes series production. Specific tests such as leak and vibration testing are carried out in certified laboratories, and defense sites are additionally certified to EN 9100/ISO 9100.
