Boilermaking

« Boilermaking is the art of understanding metal in order to shape it to one’s will. This can only be learned in contact with the material ».

Thanks to decades of experience, the boilermakers at Graux have mastered the art of thin and thick sheet metal work. Their precision can go further than the most rigorous ISO 2768 tolerances, without the need for machining.

Our fleet of recent machines allows for digitally-controlled complex folding on a length of 4500mm, the straightening of 16m profiles and 2000 mm intern rolling. Qualified partners enable us to push these boundaries even further.

The manufactured sets up to 12.6 tons and 5000 x 5000 mm can be handled.

The materials worked include carbon and stainless steel, including the refractory and Duplex ones, aluminum, and more specific metals such as high-strength steel, Inconel and anti-abrasive steel.
