Better advantage, especially for overseas projects Caledonian customers for overseas projects, we can provide: professional color pages for the project; overseas projects for examination; product samples; provides third-party test report; sea, air, etc. may be used more than ways to transport; overseas Supervision, owners face-to-face communication and product demonstrations. Caledonian already successful cooperation with many national projects, including the system of airport runways, airport baggage system (BHS), power plant control system, highway control system, highway toll systems, high-speed railway locomotives, subway cable system, Sierra door, screen door , air conditioning, PIS, cctv system.
