Since 1986, Bâtiments BUT has been designing and manufacturing prefabricated, transportable industrial buildings that are built to last and adapt to the most complex technical requirements. Whether in the port, airport, telecommunications, energy, or public services sectors, the company offers 100% customized, turnkey solutions.
Its signature: the use of high-performance materials—fiberglass, composites, and non-combustible steel—as well as a unique manufacturing process. Each building is designed, equipped (electricity, generators, specialized systems), assembled, and delivered according to the customer's specific needs.
A member of the Aeronav family since 2021, Bâtiments BUT combines local expertise, innovation, and industrial rigor to serve the Canadian and international markets with increased efficiency.

Every project is treated with the same rigorous approach, whether it is a technical shelter or a specialized structure for the airport sector. Through constant innovation, customer focus, and a passion for a job well done, Bâtiments BUT remains a leader in the manufacture of custom industrial shelters.
