Constructed with thermally broken aluminum alloy, resistant to corrosion, warping, and extreme weather (-30°C to 80°C).

2. Space-Saving Accordion Design
Multi-panel 180° folding mechanism maximizes usable space with 90% clearance efficiency.

3. Enhanced Thermal/Sound Insulation
Triple-seal gaskets and argon-filled glass reduce noise (38 dB) and energy loss (U-value ≤1.2 W/m²K).

4. Anti-Burglary Security System
3-point stainless steel locks and laminated glass meet ASTM standards, resisting forced entry.

5. Customizable Aesthetic Flexibility
50+ RAL color finishes and configurable panel layouts (e.g., 2+3 or 4+2) for modern interiors.

Sungye Aluminum 73 Folding Door: Key Advantages & Selling Points


  1. Ultra-Durable Aluminum Alloy Frame


High-strength, corrosion-resistant alloy ensures decades of structural integrity.
Sungye’s 73 Folding Door uses aerospace-grade aluminum alloy, thermally broken and powder-coated for extreme weather resistance. The frame undergoes rigorous stress testing (ISO 9001-certified) to withstand wind loads up to 120 km/h and temperature fluctuations (-30°C to 80°C). Unlike standard aluminum, its reinforced corners and anti-warping design prevent deformation, making it ideal for coastal or industrial areas.



2. Space-Optimized Folding Mechanism


Smooth, multi-panel folding maximizes usable space in compact settings.
The door’s patented hinge system allows seamless 180° folding with minimal clearance. Precision ball bearings and nylon rollers ensure silent, effortless operation even for large panels (up to 3m tall). Ideal for balconies, patios, or room dividers, it opens/closes 40% faster than sliding doors while freeing 90% of the doorway space.



3. Advanced Thermal & Sound Insulation


Triple-seal gaskets and argon-filled glass cut energy costs by 25%
Multi-chamber aluminum profiles and dual-layer tempered glass (optional Low-E coating) block heat transfer (U-value ≤1.2 W/m²K) and reduce noise by 38 dB. The airtight design eliminates drafts, maintaining consistent indoor temperatures. Perfect for eco-conscious homes or noise-prone urban areas.



4. Anti-Intrusion Security Features


Reinforced locking points and shatterproof glass meet ASTM F2090 standards.
The door integrates 3-point stainless steel locks, anti-drill hinges, and laminated glass with PET interlayers. Stress-tested against 1500N force, it resists crowbar attacks and forced entry. Optional smart locks add fingerprint/RFID access control for commercial or high-security residential use.



5. Low-Maintenance, Eco-Friendly Design


Self-cleaning coatings and recyclable materials reduce upkeep and environmental impact.
The frame’s hydrophobic powder coating repels dirt, while stainless steel hardware resists rust without polishing. All components are 100% recyclable (LEED-compliant), and the modular design allows easy part replacement, extending lifespan by 15+ years versus traditional doors.



6. Customizable Aesthetic Options


50+ finishes and configurable panel layouts adapt to any architectural style.
Choose from woodgrain, metallic, or matte finishes (RAL color-matched) and glass types (frosted, tinted, or decorative). Panels can be asymmetrically grouped (e.g., 2+3 or 4+2) for unique layouts. Slim sightlines (frame width: 65mm) enhance modern minimalist interiors.



7. Effortless Installation & Warranty


Pre-assembled components enable 3-hour installation with a 10-year warranty.
Sungye’s plug-and-play system includes laser-leveled tracks and pre-drilled frames, minimizing on-site adjustments. Comprehensive warranty covers hardware, glass, and finish against defects. Remote technical support via AR-guided troubleshooting ensures long-term reliability.
