This ensures that the aesthetic and energy models created during design are accurately realized in the installed facade.

Engineered for High-Traffic Durability: Superior Structural Stability and Weather Resistance

The structural integrity of an aluminum glass door system is defined by its alloy composition, thermal design, and glazing specification. For commercial applications, the primary load-bearing components utilize 6063-T5 or 6061-T6 aluminum alloys, which provide a minimum yield strength of 160 MPa and 240 MPa, respectively. These profiles are engineered with thermally broken polyamide strips to achieve a thermal transmittance (Uf) as low as 1.6 W/m²K, preventing condensation and thermal stress that can compromise long-term stability.

Core Functional Advantages:

• Enhanced Load Management: Multi-chamber profile designs with internal reinforcement increase the moment of inertia, allowing for larger glass spans without deflection. Integrated stainless steel or galvanized steel core reinforcements at critical stress points (hinge and lock areas) ensure cyclic load durability exceeding 200,000 cycles.
• Superior Sealant Performance: Perimeter sealing employs triple EPDM gaskets with a minimum Shore A hardness of 70, providing consistent compression set resistance. This system achieves an air infiltration rating of Class 4 (≤ 0.5 m³/m·h per EN 12207) and watertightness of Class 9A (≥ 600 Pa per EN 12208).
• Corrosion & Impact Resistance: All exposed aluminum surfaces undergo a pretreatment (chromate-free) and electrostatic powder coating process, yielding a minimum film thickness of 60μm. This finish exceeds 1,000 hours of neutral salt spray testing (ASTM B117) without corrosion. Tempered or laminated glass, typically 10-12mm thick, is standard for impact resistance.
