Innovation is in our DNA

At Saint Jean Industries we have primarily focused our expansion efforts on the market for aluminum parts as this metal offers advantages in terms of weight and mechanical properties. Considerable investment in Research and Development has helped continuously push the boundaries of design and manufacturing, resulting in significantly lighter vehicles. By incorporating new technologies, the scope of innovation was widened to include other areas. These are covered by four key concepts.
