Broadwell has the largest dome in the world—a mining dome spanning the length of 10 football fields in Inner Mongolia. Our domes can be engineered to be as wide as 300’ and virtually limitless length.
Our Clean Air, Anti-pollution Domes
These domes are installed in many schools and sports facilities that exist in high air pollution cities. These domes filter out almost 100% of pollutants and bacteria in the air, significantly reducing the PM2.5 fine particle pollution counts in the air.

Monolithic Domes
Broadwell also produces these domes which are cement domes that can be used for homes, schools, churches and other structures. These domes are extremely energy efficient and strong--able to withstand F5 tornadoes and other disasters.
