High-speed spiral door

HSD high-speed spiral door is a new type of metal industrial door that integrates speed, energy saving, sealing, wind resistance, and environmental protection. It has strong reliability and practicality, and its operating speed is more than 6 times that of industrial sliding doors. With work efficiency, hard fast doors are gradually replacing industrial sliding doors.

The door panel is produced on a large-scale assembly line using French technology. The interior of the door panel is filled with flame-retardant polyurethane industrial insulation material, and the bridge breaking design can isolate indoor and outdoor temperature loss, effectively insulation and energy-saving. The two ends are connected by hinges, and the door panels are connected by double-sided sealing strips to ensure sealing and effectively resist strong convective wind pressure.

High-speed spiral door can prevent outsiders from entering while also resisting weather changes. They can block indoor and outdoor air convection and are used in frequent access channels, making them an ideal choice for industrial energy conservation and consumption reduction.

Widely used in equipment manufacturing enterprises, automobile manufacturing enterprises, food processing enterprises, construction, commercial real estate, fire protection, underground garages, etc., as exterior doors for factory buildings, entrance doors for automobile production lines, frequent logistics channels, and entrance and exit doors for large garages, it meets various requirements of customers for wind resistance, insulation, speed, dust prevention, and energy conservation.

The first spiral high-speed door in China was born in Lefast

In 2009, China's turbine hard fast door was developed and produced in Lafayette, which was like the dawn of dawn, announcing a new chapter in China's turbine hard fast door market. This product breaks the monopoly of international brand fast door products in the domestic high-end market and fills the gap in the domestic industrial fast door market. In the same year, Lafayette Turbo hard fast door entered the Great Hall of the People, which marked the rise of China's hard fast door technology and the increasing influence in the domestic market.
