1. Multi cavity structure profiles (bridge cut aluminum) can effectively block the thermal conduction of the profiles themselves, which is the key to improving insulation.
2. Multi channel sealing design (such as three seals) can tightly fill the gap between the window sash and the window frame, preventing sound leakage.

45 ° diagonal joint, using corner code injection glue to ensure the overall performance, service life, and safety of doors and windows:

1. Ultra high structural strength: The corner code provides mechanical support, and the dedicated structural adhesive achieves molecular level bonding, effectively resisting window frame deformation, settlement, and wind pressure.
2. Ultimate sealing performance: The adhesive will completely fill all internal gaps, completely blocking the possibility of air and moisture leaking from corners.
3. Durable and long-lasting: The cured colloid has excellent weather resistance, is not easily aged, and avoids abnormal noise and looseness caused by metal thermal expansion, contraction, or vibration.

Effectively avoid harm to the human body, especially children, caused by internal fan angles.

1. Reliable Material: Key components are made of high-strength aluminum alloy, zinc alloy, and stainless steel to ensure durability.
2. Exquisite craftsmanship: The surface is treated with multiple layers of electroplating, powder coating or anodizing to form a dense protective layer, which is corrosion-resistant and scratch resistant.
3. System matching: Emphasize the precise adaptation of the entire solution to specific door and window profile systems, ensuring easy installation, functional implementation, and performance compliance.

1. Waterproof and leak proof are more reliable: Rainwater is effectively discharged outward. Reduce the risk of rainwater 'backflow' during strong wind weather.
2. Improve air tightness and sound insulation: Reduce air convection channels, enhance the air tightness of windows, help strengthen insulation and isolate external noise.
3. More concise and beautiful appearance: The drainage holes are hidden at the bottom or side of the profile, almost imperceptible from the outside.
4. Dust and insect proof, easy to maintain: The drainage holes are equipped with invisible drainage covers or windproof covers, which can prevent mosquitoes and large particles of dust from directly entering the profile cavity.
