Why has aluminum casement door become the preferred choice for wind resistance in high-rise buildings?

1. High strength aluminum alloy: a perfect balance between lightweight and deformation resistance
Aluminum Casement Door adopts 6005-T5 or 6063-T6 grade aluminum alloy profiles, with a tensile strength of 160-240MPa, far exceeding plastic steel (60-80MPa) and ordinary carbon steel (120-150MPa). High rise buildings can withstand wind pressures of over 3.0kPa under strong winds

2. Broken bridge structure: blocks heat conduction and enhances structural stability
The broken bridge design of Aluminum Casement Door is achieved by embedding PA66 nylon insulation strips between the inner and outer layers of the profile, forming a physical isolation layer. This structure not only reduces heat transfer by more than 60%, but also tightly fixes the door leaf and frame through a multi-point locking system

3. Multi channel sealing system: eliminating leakage and noise
The wind-induced vibration effect of high-rise buildings can easily lead to the failure of door and window seals. Aluminum Casement Door is equipped with three EPDM sealing strips (inner and outer sides+middle pressure chamber), combined with a hidden drainage channel, which can withstand a pressure difference test of ± 6000Pa without leakage.

4. Weather resistance and anti-corrosion: responding to extreme climate challenges
The surface of Aluminum Casement Door is treated with fluorocarbon spraying or anodizing, with a salt spray corrosion resistance time of over 3000 hours (ASTM B117 standard), suitable for high humidity coastal areas.

5. High precision hardware accessories: the "invisible guardian" against wind pressure
The load-bearing hinge of the Aluminum Casement Door is forged from 304 stainless steel, and a single door can bear a weight of over 150kg, with a lifespan of 100000 opening and closing cycles. Multi lock point system (usually ≥ 3) combined with windproof and anti pry design can maintain a tight fit between the frame and fan even under negative wind pressure, avoiding door vibration caused by wind fluctuations.
