About Us
: The Triangle Group
The Founding of the "
Le Triangle" Group
Le Triangle began as a farming cooperative: Gilles Deshayes and his two brothers founded their GAEC (Groupement Agricole d'Exploitation en Commun). The trio thus began their business on a triangular plot of land, hence the name of the current company. In 1988, he invented a waste-reducing collar for his poultry farm and began mass-producing his invention.
In 1990, he decided to manufacture his own buildings, which he would also develop for his fellow farmers. The company’s business is now focused on the manufacturing and construction of agricultural buildings. The turning point for solar energy came in 2009: he installed photovoltaic panels on the factory roof and was convinced of their value. He then began offering his customers the option to install them as well, and the initiative was a resounding success.
Gilles surrounds himself with employees, creates new subsidiaries to serve different markets, and continues to grow the group. Today, Gilles is joined by his sons, Rémi and Vincent, who are taking the reins of the company.
