GHM specialises in metallurgy. It was founded before 1840 and is the heir to four art foundries from the 19th century: Durenne, Val d’Osne, Ducel and Dommartin.
GHM currently employs a workforce of almost 650 people in France. Located in Champagne and Lorraine, its four main factories convert cast iron, aluminium, bronze and steel. They also handle the machining, assembly and finishing operations.

Today, GHM employs its expertise in foundry, boiler making, metalwork and metal machining. In this last specialty, the company distinguishes itself in the trade by its mould modelling operations and the hand moulding and casting of complex parts. The model for the mould is created using sand from the model plates, then proceeds to manufacturing and the fusing of the cores to create the hollows. Once the assembly is closed, the alloy is poured into the mould. After cooling is completed, the mould is broken (shake out), the piece is separated from the flow from casting (deburring) then ground to obtain a first level of finish. The majority of orders come from local authorities and public contracts obtained directly (cities of Lyon, Nice, Nantes) or via companies (Vinci Energies, ENGIE-INEO, Bouygues, Spie, etc.) for the cities of Nice, Dijon, Paris, Nancy, Reims, Strasbourg, Chaumont, etc.

The company regularly takes part in the restoration of heritage items: illuminations at the Louvre, the gates of the Jardin des Plantes, the Guimard metro entrances.
