1. Multi-cavity structure profiles (bridge cut aluminum) effectively block thermal conduction, improving overall insulation.

2. Multi-channel sealing design (three seals) tightly fills gaps between the window sash and frame, preventing sound leakage.

Using 45° diagonal joints and corner code injection glue to ensure performance and safety:

• Ultra-high structural strength: Resists deformation and wind pressure.
• Ultimate sealing: Adhesive fills internal gaps, blocking air and moisture.
• Long-lasting: Weather-resistant colloid avoids noise and looseness.

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

1. Reliable Material: High-strength aluminum, zinc alloy, and stainless steel.

2. Exquisite Craftsmanship: Corrosion-resistant and scratch-resistant multi-layer coating.

3. System Matching: Precise adaptation to profile systems for performance compliance.

1. Reliable waterproof and leak-proof design prevents rainwater backflow.

2. Enhances air tightness and isolates external noise.

3. Concise appearance with hidden drainage holes at the bottom or side.

4. Dust and insect-proof covers protect the profile cavity.
