L’hexagone, specialist in cardboard honeycom construction

1890

Jean ROSSIGNOL (1867-1933) creates a sawmill at Argentré-du-Plessis (in Ille-et-Vilaine) to make use of his steam engine outside the harvest season. The engine was originally intended to power threshers in the fields around Vitré. After the First World War, Rossignol acquires some circular saws and builds a stable-block for the 21 horses that are used in skidding and transporting timber from the region’s forests.

1925

Alfred ROSSIGNOL (1910-1981) is joined by his son, Alfred, who develops the sawmill, diversifying into the manufacture of parquet, boxes and poplar crates for vegetable growers and egg-sellers such as « Bridel », the Breton dairy business. Alfred ROSSIGNOL also starts to use lorries for distribution, and they gradually take over the role traditionally played by horses.

1953

René ROSSIGNOL (1936-2015) joins his father to manufacture standardised flush doors, using the old stable block as his workshop. He begins by producing 15 doors a day.

In 1957 production has reached 220 doors a day, and in 1968, following successive extensions and building work, the factory covers an area of 5000 m2 and production hits 2800 doors a day. A sister factory is created in Pertre, close to Argentré-du-Plessis, producing door assemblies, entrance doors and garages.

1971

The company « l'hexagone » is created and takes over a small building that René Rossignol buys at La Guerche-de-Bretagne, not far from Argentré-du-Plessis. It is the first company in France to manufacture cardboard honeycomb, used to pack the inside of flush doors and plasterboard. Five people start work in production. René ROSSIGNOL Rossignol leaves the Rossignol family business at Argentré-du-Plessis in 1973 to focus exclusively on « l’hexagone » at La Guerche-de-Bretagne.

1979

He builds a honeycomb panel production line, mainly for the manufacture of cardboard pallets, and load spreaders for industry, dividers for the storage and protection of sheets of glass during transport, and shock-absorbent cushions for the dropping and parachuting of military equipment and vehicles.

1984

New machines are developed to manufacture customised packaging and inserts, and a range of different components and containers for industry. The company’s talent for innovation is acknowledged in 1984 and 1986 by the award of an « Oscar » by the packaging industry.

1990

François ROSSIGNOL (1968-) joins his father and starts working in the design office before installing the IT systems.

1995

René Rossignol reopens a paper mill in Saint-Michel-de-Castelnau (Gironde). The mill, « Papeteries du Ciron » provides a steady supply of raw materials to l’hexagone until the end of 2011.

2001

François ROSSIGNOL takes over at « l’hexagone ».

2004

The production workshops and offices are reunited on a single site, located just 100 m from the historic base.

2009

The three-phase method of manufacturing the honeycomb is abandoned in favour of a new production tool that can manufacture in a single phase.

2011

Significant investments are started to upgrade honeycomb panel production line, optimising productivity and manufacturing capabilities.

2015

The « clic-clac » pallet is developed, followed by the clic-clac box aimed at the POS market. A range of insulated pallet boxes made from « nidalu » honeycomb panels is created. The nidalu panel is refined to improve its thermal resistance performance. New investments result in enhanced productivity on the honeycomb panel production line.

2016

A new line is installed for cutting and stamping honeycomb panels.
