As Eric Troupin explained to us: “In this business, it is difficult to compete in terms of price with emerging countries, but certainly not for service, quality, proximity, engineering and know-how. that make all the difference. That is why we continue to invest in the best of technology and in the competence and experience of the staff ”.
