Sheet metalwork and welding
We are constantly striving for excellence to ensure we are recognised for our expertise in welding operating methods, that our team of sheet metalworkers are constantly being trained, and that we meet client specifications and standards (ISO and ASME).
BONNAVION is a member of the SNCT (Syndicat National de la Chaudronnerie – Tuyauterie – Maintenance Industrielle), the Association Française du Soudage (AFS) and COFREND. We constantly and actively monitor welding technology, building codes and ISO and ASME standard specifications.
WELDING : RECOGNISED EXPERTISE
