  • GA EW50 Curtain Wall System – Engineering, Materials & Technical Specifications

    1. Overview of the GA EW50 System

    The GA EW50 Curtain Wall System by GLASS AROUND is a high-performance aluminum and glass façade solution, designed for commercial, residential, and high-rise buildings. It offers exceptional thermal and sound insulation, mechanical strength, and architectural flexibility, making it a preferred choice for large-scale and complex projects worldwide.

    This system is available in three main configurations:
    ✔ GA EW50 Standard – Features visible external caps with multiple decorative covers for a classic and modern appearance.
    ✔ GA EW50 Structural Glazing – Minimizes the visibility of aluminum from the exterior, creating a seamless glass façade.
    ✔ GA EW50 Linear – Combines Standard and Structural solutions to create a linear aesthetic effect, ideal for architectural precision designs.

    2. Material Composition & Structural Performance

    2.1. Aluminum Profiles & Properties

    The system is built using 6063-T6 and 6005-T5 aluminum alloys, offering high strength, durability, and corrosion resistance.

    Alloy Type Density (g/cm³) Tensile Strength (MPa) Yield Strength (MPa) Elongation (%) Hardness (Brinell HB)
    6063-T6 2.7 241 214 12 73
    6005-T5 2.7 260 240 10 85

    All profiles comply with ASTM B221 and EN 755-2, ensuring superior mechanical performance and weather resistance.

    2.2. Surface Finishing & Coatings

    All aluminum components undergo high-end pre-treatment and finishing processes for extended durability:
    ✔ Anodizing (25µm – 30µm, Class 1) – Provides UV protection, scratch resistance, and corrosion resistance
    ✔ Powder Coating (AkzoNobel, Axalta, Jotun) – Offers Qualicoat Class 2 certification, ensuring seaside-grade durability

    Available Finishes:

    • Standard Colors: RAL 9016 (White), RAL 9005 (Black), RAL 7016 (Anthracite Grey)
    • Custom Powder Coating Shades available upon request
    • Anodized Finishes: Silver, Bronze, Champagne, Black
