I consider that GRAUX is a ‘rare’ company. Rare by virtue of the very high level of quality of the products its supplies, the listening ability of the persons with whom I am in contact and the company’s very competitive prices.

GRAUX’s strong points are the quality of their work and their production possibilities. They have some well-equipped workshops and can achieve some impressive things.

GRAUX is the only company in the sector to submit such detailed and complete bid packages. Both technically and commercially, it would be good if everyone could be like them.

GRAUX’s competitiveness in technical and qualitative terms is very good. This is borne out by the large number of checks that we carry out throughout the production process up to delivery.

As far as we are concerned, GRAUX has several important strengths: highly flexible, great adaptation capacity and a very high level of technical expertise in its work.

GRAUX is different from its competitors, not just as a mechanical workshop, but also by its moderate size and the availability of its management team and project managers. Their strong points lie in their ability to respond within the required lead times and with the necessary precision of work.

Graux has real human capital, combining high skill levels – particularly in sheet metal working and welding. The management team is young and dynamic. With a company like GRAUX, one is reassured, not worried.

GRAUX stands head and shoulders above all other companies offering, as they do, mechanical welding and with which I have had dealings in the past.

For me, what distinguishes GRAUX from the competition is its straightforwardness. It is a relation without any hidden agenda, where one works openly, with real strengths in boiler making and mechanical welding.
