Message from our CEO
The development of Spain in the 1970s allowed companies such as CONTROL Y APLICACIONES (CAE) to participate in the assembly and start-up of new industrial facilities. The teams involved in commissioning process remained at the plant, constituting the first maintenance team.
The growth and consolidation of this activity led to the creation of Mantenimiento y Montajes Industriales, MASA, in Tarragona on 22 November 1976.
Our dedication to Client Service from the beginning, combined with the Experience of our personnel and continuous Growth by incorporating new activities, has enabled the building of a solid Group of national and international companies which are part of COBRA INDUSTRIAL SERVICES.
We celebrate our 50th anniversary year by extending our gratitude:
- To our clients for their trust
- To our suppliers for their collaboration
- And, above all, to our personnel for their daily effort and commitment.
Reaching fifty years is a major SUCCESS.
Congratulations to all!
