Hard-wound rapid door

The hard spiral rapid door, also known as the turbine hard rapid door, is a high-end metal high-speed industrial door, distinct from ordinary PVC rapid rolling shutters and rapid stacking doors. Its core innovation lies in the spiral turbine track storage structure. The double-layer aluminum alloy hard door panels separate and rotate to be retracted along the curved spiral track. There is no adhesion or friction between the door panels, achieving high-speed, quiet, wear-resistant and long-lasting operation.

The opening and closing speed can reach 0.6–2.0m/s. It supports 800–1200 high-frequency uninterrupted passage per day. It integrates five core performance features: anti-theft, high-strength wind resistance, bridge insulation, full-sealed dustproof, and ultra-fast intelligent opening and closing. It is applicable to indoor and outdoor scenarios and is the preferred high-end door type for modern intelligent factories, cold chain, high-end garages, and clean workshops. Tianjin Hongtuo Leke can customize standard models, low-temperature cold storage models, and explosion-proof and anti-corrosion models of hard spiral rapid doors according to customer needs.
