Client focus to deliver excellence

Our client focus drives us to constantly question and assess our practices

It stems from our ambition to be the best equipped to answer their varied needs.

This continuous effort encourages us to:

– Develop our range of services, capabilities and areas of expertise
– To set up facilities close to the main French oil refineries hubs in order to optimise reaction times.


a group recognised for its expertise

Since 1981, the branches of our group have grown thanks to the thoroughness of their approach, their drive for excellence and technical abilities.

We have become a benchmark in metalworks on storage tanks because we have successfully acquired undeniable expertise and knowhow that our clients can benefit from.


MATEN SECOMOC Group offers metalwork services targeted at major clients in the energy, chemical, siderurgy, defence and agro industries.

The core expertise around which the MATEN SECOMOC Group was built is the construction of large steel storage tanks. Our clients can benefit from a global offer including engineering studies, construction, maintenance and repairs as well as other associated services; all performed by our own production teams. Our different branches have developed specialised skills that can be applied not only to storage tanks but also to freight boats or nuclear domes, amongst many other projects.

Each branch offers a different specialisation: engineering studies by ECCR, industrial metalwork by SECOMOC and SECOMOC TCM, industrial piping by EGIRSAI, dimensional controls by MATEN Metrology, non-destructive controls by PROCI.

All these branches are able to combine their respective strengths to complete a global project or operate independently for their own specific clientele.

This ability to federate its branches around global projects is the cornerstone of MATEN SECOMOC Group’s successes with its clients, particularly with international projects.
