From its founding in 1984, the OXYMETAL Group started as a specialist in flame cutting services. 


Then, at the beginning of the 1990s, the Group focused its development on laser cutting, with the creation of a workshop in Bordeaux, now OXYMETAL SUD-OUEST.


Other sites would join the Group throughout the 1990s: Metz, Paris, Nantes.


Keen to provide its customers with a comprehensive range of finished products, the OXYMETAL Group diversified at the beginning of the 2000s and broadened its range of services to welding, machining and mechanical assembly operations.


In 2007, with the takeover of the company OSC, the OXYMETAL Group added the manufacture of OSC® Test Weight Sets to its range, specific products designed for regulatory tests on lifting equipment and machinery, which are the subject of several patents.


Today, the OXYMETAL Group endeavours to maintain a highest level of quality for all of its activities and to provide the best solution to the constantly-increasing requirements of its Customers.


As such, investment in new and ever more efficient machines and in the ongoing training of its employees are strategic choices and priorities for the OXYMETAL Group.


Today, the expertise of the OXYMETAL Group is applied in numerous business sectors ranging from mechanical engineering to jewellery, as well as building and civil works, metal architecture, agri-food, energy, aerospace, railway transport and automobile. Highly varied and complementary areas of competence.


The sites are located across the entire French territory drawing on inter-site synergy and complementarity. All metals can be cut: steel, aluminium, copper or stainless steel, to mention only a few, with thicknesses ranging from 0.2mm to 260mm, using CO2 laser, fibre laser, YAG laser or flame cutting.
