Ronéo is a historic manufacturer of metal office furniture, founded in the early 20th century around administrative equipment (filing, typing, duplication) and with a strong presence in France from the interwar period onward. It is renowned for its filing cabinets and cabinets made of stamped sheet steel, designed for town halls, factories, and railways: robust construction, hinged fronts with label holders, internal stops, and standardized sizes. In the 1950s–70s, Ronéo widely distributed its product lines (in gray, "workshop" green, and hammered finishes), which have since become icons of industrial style. These pieces are distinguished by their modularity (stackable columns), durability, and a highly sought-after patina. When properly restored, they offer generous and stylish storage in a contemporary interior, office, or shop.
