Security: High-strength slats (such as aluminum alloy, stainless steel, or thickened steel) combined with precision locks effectively resist external force damage such as prying and smashing.
Fire Resistance: Fireproof roller shutter doors automatically descend during a fire, forming a fire-resistant barrier with a fire resistance rating of ≥3.0 hours, preventing the spread of fire and smoke, and ensuring the safety of evacuation routes.
Wind Resistance: Internal wind-resistant keels and thickened materials can withstand strong winds and typhoon impacts, making them suitable for coastal or windy areas.
Environmental Isolation Functions
Dust, Insect, and Wind Protection: High-speed roller shutters reduce air convection through rapid opening and closing (0.5–1.6 m/s), maintaining workshop cleanliness.
Thermal Insulation and Heat Preservation: Some slats are filled with polyurethane foam or use a double-layer structure to improve energy efficiency.
Soundproofing and Noise Reduction: Sealed guides and brush strips effectively reduce noise transmission.
Convenience and Intelligent Functions
Electric/Remote Operation: Supports one-button start/stop and remote control; some models integrate radar and geomagnetic sensing for automatic opening and closing.
Firefighting Linkage: Fireproof roller shutters can be linked with smoke and temperature alarm systems, automatically descending in stages (e.g., first to 1.5 meters, then fully closing after a delay).
Emergency Manual Function: In case of power failure, can be operated manually via chain or crank, ensuring usability in emergencies.
