A family business created in 1945 by the former Senator-Mayor of Lyon Francisque Collomb, Chimicolor leaves its professional mark on all metal surfaces: the surface of the metal is chemically prepared (sulfuric anodic oxidation), the marking is done by screen printing, it is made durable by sealing or applying a protective varnish, the parts are then cut by numerically controlled punching.

The company also has extensive expertise in engraving processes (chemical, laser or mechanical).
