Project Overview
Air-supported structures are widely used in cement plants, coal storage facilities, coal trading centers, and mining projects. These enclosed structures help reduce dust emissions, improve working conditions, and support environmental compliance.
LEFAST HSD4322Q High Speed Spiral Doors are commonly installed at vehicle access points in such facilities, with reference projects including Qilian Mountain Cement, Shanxi Coal Storage Domes, Wensu Coal Trading Center, and Guotai Xinhua Mining.
Challenge
Bulk material storage domes rely on internal air pressure to maintain structural stability. During vehicle movements, pressure fluctuations must be minimized, requiring reliable interlock control between multiple doors.
At the same time, doors are continuously exposed to internal pressure and wind loads. Conventional door panels may deform over time, creating higher demands for structural strength and long-term reliability.
LEFAST Solution
LEFAST provides HSD4322Q High Speed Spiral Doors with interlock control capability, enabling coordinated operation with air-supported structure management systems and helping maintain stable internal pressure.
Designed specifically for long-term pressurized environments, the reinforced panel structure of HSD4322Q delivers enhanced wind resistance and deformation resistance while maintaining cost efficiency, supporting openings up to 12 meters wide.
