Sale with the professionals

The company Janvier Gruson Prat has been making cold-stamped copper items since 1840. It sells its products under the names Artmetal and Framex.

It also sells metal buttons under the name Coinderoux (TWW). The company provides stamped items for costume jewellery, gold work, lighting, furnishings, decoration, insignia and medals, as well as metal buttons for fashion and civilian and military uniforms.

The collection has over 120 000 models, with a wide choice of engravings from buttons and filigree items to jewellery claws or galleries, including patterns, animals and flowers. 


The  3000m2 factory in Savigny-le-Temple has stamping and cutting, welding, assembly and surface treatment (vibratory finishing, shiny and mat pickling, gilding and silvering, enamelling) workshops. The items, in copper, without nickel or lead, can be made to order in gold, silver, copper or tin.


The company’s know-how is rare in France and covers engraving and stamping, making punches, matrices and tools for outlining, cutting out and pressing, as well as stamping, turning and burnishing metal buttons. Its know-how is unique.


Recognised stylists, jewellers, luxury French and international department stores and interior architects order Artmétal, Framex and Coinderoux models, which appear on podiums or in prestigious venues in European capitals.

The company is currently seeking ISO 14001 certification.
