Will aluminum alloy rolling shutter doors really not deform in hurricane weather?

Whether aluminum alloy rolling shutter doors deform in hurricane weather depends on many factors, including the material of the rolling shutter door, structural design, installation quality, and the strength of the hurricane. The following is a detailed analysis of this issue:

1. Material characteristics of aluminum alloy rolling shutter doors
Aluminum alloy rolling shutter doors are usually made of high-strength aluminum alloy materials, which have the following characteristics:

High strength: Aluminum alloy has high strength and can withstand large wind pressure. For example, the tensile strength of 6063T5 aluminum alloy rolling shutter doors can reach 300-500 MPa, which can effectively resist the impact of strong winds.

Corrosion resistance: Aluminum alloy has good corrosion resistance, and a dense oxide film will form on the surface, which can effectively prevent the material from corroding in bad weather.

2. Structural design of aluminum alloy rolling shutter doors
The structural design of aluminum alloy rolling shutter doors is crucial to their wind resistance:

Reinforcement ribs and support structures: Some high-quality aluminum alloy rolling shutter doors will add reinforcement ribs and support structures during design to improve the stability and wind resistance of the door body. For example, the effective width of the DAK77 double-layer aluminum alloy curtain blade is 77mm. The unique sound-absorbing leather strip design between the curtain blades makes the door body truly silent when rotating; the unique mechanism of thickening and widening the aluminum alloy guide groove plays a role in the wind resistance of the large-span door body.
Sealing performance: Good sealing performance can not only prevent the invasion of rain and wind and sand, but also improve the overall strength of the door body. Aluminum alloy rolling shutter doors usually use double-row sealing sound-absorbing wool strips and bottom rubber seals to form a four-sided airtight structure, which effectively prevents the circulation of internal and external air when closed.
3. Wind resistance of aluminum alloy rolling shutter doors
Depending on different designs and materials, the wind resistance of aluminum alloy rolling shutter doors is different:

Ordinary aluminum alloy rolling shutter doors: The wind resistance of ordinary aluminum alloy rolling shutter doors can generally reach about level 10. Under the conditions of a level 10 hurricane (wind speed of about 89-102 kilometers/hour), ordinary aluminum alloy rolling shutter doors can usually remain stable and will not deform easily.
High wind-resistant rolling shutter doors: Some specially designed aluminum alloy rolling shutter doors, such as hard fast rolling shutter doors, can have a wind resistance level of 12 or even higher. These rolling shutter doors adopt a broken bridge insulation structure design, which not only has good thermal insulation performance, but also has light weight, high strength and strong impact resistance.
IV. Performance in practical applications
In practical applications, the performance of aluminum alloy rolling shutter doors in hurricane weather is as follows:

Performance after Typhoon “Bebejia”: After Typhoon “Bebejia”, some buildings equipped with aluminum alloy rolling shutter doors performed well, and the rolling shutter doors did not show obvious deformation or damage. This shows that under 10-12 level hurricane conditions, high-quality aluminum alloy rolling shutter doors can effectively resist the impact of wind.
Application in coastal areas: In coastal areas, aluminum alloy rolling shutter doors are widely used in factories, warehouses, commercial buildings and other places. Buildings in these areas are often threatened by hurricanes, and the wind resistance of aluminum alloy rolling shutter doors has been verified in practice. For example, the aluminum alloy rolling shutter doors installed in a factory in a coastal area withstood the test in a level 14 hurricane without deformation or damage.
5. Factors affecting the deformation of aluminum alloy rolling shutter doors
Although aluminum alloy rolling shutter doors have high wind resistance, they may still deform in some cases:

Hurricane strength: If the strength of the hurricane exceeds the design wind resistance level of the rolling shutter door, the rolling shutter door may be deformed or damaged. For example, a Category 17 hurricane (wind speed exceeding 250 km/h) may cause serious damage to ordinary aluminum alloy rolling shutter doors.
Installation quality: If the rolling shutter door is not installed firmly, the guide rails and bottom beams are not firmly connected to the wall, the rolling shutter door may loosen or fall off in a hurricane. Therefore, it is necessary to ensure that all parts are firmly connected during installation.
Maintenance and care: Regular maintenance and care can extend the service life of the rolling shutter door and ensure its performance in hurricane weather. For example, regularly check the sealing strips and connectors, and replace damaged parts in time.
Conclusion
Aluminum alloy rolling shutter doors are usually not easily deformed in hurricane weather, but their wind resistance depends on the material, structural design, installation quality and hurricane strength of the rolling shutter door. High-quality aluminum rolling shutters can remain stable in hurricane conditions of 10-12, but in higher-level hurricanes, they may be deformed or damaged. Therefore, choosing a high-quality rolling shutter and ensuring it is properly installed and maintained is the key to ensuring it performs well in hurricane weather.
