Commercial modular building manufacturers and dealers represent an annual multi-billion dollar industry. From classrooms to airport terminals, dormitories to weigh stations, emergency rooms to restaurants, MBI member companies manufacture, install, service, and lease every conceivable type of building, both temporary and permanent. While factory-built structures are already in use in every state of the U.S., all across Canada, and throughout the world, the commercial modular industry is one that only continues to grow.
