Enhanced Security
• "Four-Side, Six-Point Locking" Patent: Multi-directional locking mechanism embedded in the frame, significantly improving anti-burglary performance.
• Reinforced Structure: High-tensile aluminum alloy profiles with diamond grille reinforcements deter forced entry.
Superior Insulation & Weather Resistance
• Thermal Barrier Design: Multi-chamber profiles with 44mm-wide PA66 nylon thermal breaks minimize heat transfer (U-value ≤1.8 W/m²K), reducing energy loss by up to 40%.
• Triple-Seal System: Hydrophobic gaskets and precision drainage channels achieve IP54-rated waterproofing and airtightness, preventing leakage in extreme weather.
• Acoustic Performance: 27A double-glazed units (5mm glass + 27mm air gap + 5mm glass) reduce noise by ≤35dB, ideal for urban environments.
Durability & Low Maintenance
• "Samsung" Green Building Material Certification: Compliant with China’s highest eco-standard, using recyclable aluminum and low-emission (Low-E) glass.
Durability & Low Maintenance
• Corrosion-Resistant Alloy: Surface-treated with nano-coating for UV and oxidation resistance.
• Premium Hardware: German-engineered components from HOPPE (handles) and G-U (hinges) ensure smooth operation and longevity.
