“Boilermaking is the art of understanding metal to do what you want with it. This can only be learned through contact with the material”.

Thanks to their decades of experience, the boilermakers of GRAUX have mastered the work of thin and thick sheet metal. The precision of their work can go further than the most demanding tolerances of ISO 2768, without machining intervention.

The recent machine park allows complex bending by programming over a length of 4500 mm, straightening of 16 m profiles, internal rolling over 2000 mm. Qualified partners allow us to exceed these limits even further.

The manufactured assemblies can be handled up to 12.6 tonnes and 5000 x 5000 mm.

The materials worked are steels carbon, stainless steels including refractories and Duplex, aluminum, and more specific metals such as high-strength steels, Inconel, abrasion-resistant steels, etc.
