Set up in 1971, the nearby Grandpuits subsidiary originally specialised in transporting chemical products (ammonium nitrate in hot solution, alkali, nitric acid, urea). In 1992, Bruno diversified into cold products, while retaining his expertise in hot products. The company has been able to adapt and expand its range of activities by transporting LPG, bitumen and construction products. Today, its main activities are transporting bulk and packaged chemical products, and delivering air gases in tankers to industries, hospitals, and food and pharmaceutical companies.
