To provide the necessary response and the ideal solution to each of our clients’ needs in the fastest and most effective way possible to help them improve their competitiveness with the highest guarantees of industrial quality and care for our planet.

After the arrival of General Motors in Zaragoza, Roberto Iglesias Barrera started a small auxiliary company in 1993, designed to comply with the flexibility, comprehensive service and quality demands required to work with the multinational car manufacturer. Since then, Entrerrios Servicios Generales has continued to adapt to the new needs and demands of the market, while committed to the clients with which it has been working since its inception, such as the Figueruelas plant, Stellantis, and Siemens Spain.
Throughout these years Entrerrios Servicios Generales has carried out several outstanding projects within the automotive sector, such as the construction of extensions to the Opel España plant buildings and new installations for the different generations of the Opel Corsa and other models assembled at the Aragonese plant.
The company has also carried out important industrial projects at all the other automotive plants located in Spain. Currently, they are suppliers of Opel, Volkswagen, Seat, Mercedes, Ford and Audi for whom they develop installations, in collaboration with the “TIER1” service companies, for the new generations of vehicles assembled at these plants.
Entrerrios has also taken part in the development of industrial installations at Filtros Mann, BSH and the airports of Madrid (T4), Ibiza, Santiago de Compostela, Mallorca and Köll Bonn in Germany, in addition to other facilities such as the Jean Rostand school in Nimes and the Bordeaux railway station in France, the high-speed train (AVE) station in Zaragoza, Expo 2008 and the building of the Provincial Court of Zaragoza.
