Our tapered flagpoles and medal award flagpoles are combined with Chinese and Germany technology. We use imported electric program-controlled mini flag-raising devices to ensure that the time of flag-raising and the national anthem are synchronized, and that the flagpoles are fault-free in 10, 000 trials. As the flag pole supplier of the Beijing 2008 Olympic Games, YAOLONG company has made great contributions to the great development of the Olympic Games. The flagpoles are used in flag-raising events such as the flag-raising ceremony for the opening ceremony of the National Stadium (Bird Nest), the outdoor welcome flagpole occasion, the National Stadium, the National Convention Center, etc.
