Sirail’s production sites are linked to each other and have harmonised production processes to ensure that our customers’ Requirements are met promptly and efficiently. Sirail offers the most adapted production sites, in terms of distance, cost, language and culture.

Local and reactive production

Our sites in Europe – 2 in France (Crespin and La Canourgue), one in Germany (Berlin) and one in Italy (Follo) – are dedicated to the final integration, to prototyping and to small or start of series, with highly qualified and experienced personnel. These local sites also enable the implementation of just-in-time delivery solutions.

4 sites in Europe

Cost-optimized production with quality

Our “Best Costs” production sites (in Tunisia and Morocco) combine flexibility with an optimal cost structure. Centralised purchasing and logistics enable to bring economic optimisation to materials. All our production sites answer to the strongest quality standards, are certified according to the same standards and have the means to perform all necessary control operations and tests.

Efficient industrialization for optimized production

Optimizing production requires efficient and optimal industrialization. Each Sirail site has its own “methods” department, close to production: this guarantees reactivity and continuous improvement of manufacturing processes, in close collaboration with operational teams. Our methods engineering teams define the specific resources (processes and tools) needed to implement changes in your product configuration, and to guarantee the expected level of reactivity and quality.

Product testing & certifications

All Sirail sites are equipped with the necessary means to perform the standard quality tests required for products and electrical assemblies. Test reports are provided according to the requested frequency, and your quality specifications are checked by our quality teams located on each Sirail site. More specific tests, such as waterproofing or vibration tests, are carried out in certified laboratories close to the production site. Finally, serial production only starts after your validation of the first article (FAI First Article Inspection). Quality Excellence is a reality for Sirail!

Use case

RER New Generation

Railway Electrical equipment

As part of a project to manufacture and deploy the new generation of rolling stock for Paris’s public transport system (RERNG), SIRAIL is contributing to its customer’s success by being its partner in innovation, through the design and manufacture of electrical equipment designed to incorporate the electrical and electronic equipment required for the train’s proper operation.

SIRAIL has designed electrical equipment with the aim of optimizing the space available for passengers by proposing customized solutions:

  • Mechanical, electrical and thermal studies
  • Definition of mechanical drawings and electrical diagrams
  • Space occupancy simulations
  • Study and simulation of cabling routing using mock-ups
  • Qualification of equipment through type testing (thermal, shock and vibration)
