We have completed a new shipment of aluminum sheets intended for curtain wall and building facade applications. These sheets are processed to meet the requirements of architectural cladding, offering a combination of light weight, corrosion resistance, and design flexibility.<\/p>\n\n\n\n

Common Alloys for Curtain Wall Panels<\/h3>\n\n\n\n

Three alloy series dominate the curtain wall market, each chosen for specific performance requirements: <\/p>\n\n\n\n

Key selection notes:<\/strong><\/p>\n\n\n\n

AA5052<\/strong>\u00a0\u2013 Chosen for higher strength requirements, such as tall buildings or coastal projects exposed to salt spray.<\/p>\n\n\n\n

AA1100 H14<\/strong>\u00a0\u2013 Best formability for deep-drawn or sharply curved panels.<\/p>\n\n\n\n

AA3003 H16<\/strong>\u00a0\u2013 Standard workhorse for general exterior cladding, balancing strength and workability.<\/p>\n\n\n\n

AA5005<\/strong>\u00a0\u2013 Preferred when an anodized finish is specified, as it produces a consistent, streak-free surface.<\/p>\n\n\n\n

Standard Dimensions and Tolerances<\/h3>\n\n\n\n

The following dimensions are commonly requested for curtain wall panel production:<\/p>\n\n\n\n

\u0422\u043e\u043b\u0449\u0438\u043d\u0430<\/strong><\/th>Width<\/strong><\/th>Length<\/strong><\/th>Tolerance Class<\/strong><\/th><\/tr><\/thead>

Most requested combination:<\/strong> 2.0 mm thickness x 1250 mm width x 2500 mm length in 3003 H14.<\/p>\n\n\n\n

Thicker panels (3.0 \u2013 4.0 mm) are typically used for larger unitized curtain wall systems where panel stiffness is critical without adding excessive weight.<\/p>\n\n\n\n

Dimensions Based on Recent Orders<\/strong><\/p>\n\n\n\n

The following dimensions have been frequently requested by our clients for curtain wall panel production. This shipment includes a range of sizes to accommodate different project requirements.<\/p>\n\n\n\n

Surface Finishes and Coatings<\/h3>\n\n\n\n

Aluminum sheets for curtain walls are often supplied with a mill finish for in-house coating, or pre-coated with:<\/p>\n\n\n\n

    \n
  • PVDF (polyvinylidene fluoride) coating<\/strong> \u2013 Excellent weather resistance, color retention, and UV durability. Standard colors include silver, bronze, dark grey, and custom RAL shades.<\/li>\n\n\n\n
  • Polyester powder coating<\/strong> \u2013 Cost-effective option for interior applications or less exposed facades.<\/li>\n\n\n\n
  • Anodized finish<\/strong> \u2013 Provides a metallic appearance with good scratch resistance, available in clear, bronze, or black.<\/li>\n<\/ul>\n\n\n\n

    For this shipment, the sheets were supplied in mill finish, allowing the client to apply their own coating system locally.<\/p>\n\n\n\n

    Key Applications in Building Construction<\/h3>\n\n\n\n

    Exterior Curtain Walls<\/strong>
    Non-structural cladding systems attached to the building frame. Aluminum panels provide a modern appearance, wind load resistance, and thermal efficiency when combined with insulation.<\/p>\n\n\n\n

    Spandrel Panels<\/strong>
    Used to conceal structural elements between floors. Aluminum sheets are formed into trays or flat panels and often match the color of vision glass.<\/p>\n\n\n\n

    Column Covers and Soffits<\/strong>
    Decorative cladding around structural columns and under eaves or canopies. The formability of 1100 and 3003 alloys allows for curved or folded profiles.<\/p>\n\n\n\n

    Louvers and Sunscreens<\/strong>
    Perforated or solid aluminum panels used for solar control and ventilation. 5052 is preferred for longer spans due to its higher strength.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Quality Control Points<\/h3>\n\n\n\n

    Each sheet is checked for:<\/p>\n\n\n\n

      \n
    • Thickness tolerance:<\/strong> \u00b10.02 mm for standard grade<\/li>\n\n\n\n
    • Flatness:<\/strong> Suitable for roll forming or press brake bending without oil-canning<\/li>\n\n\n\n
    • Surface condition:<\/strong> No roll marks, scratches, or dirt that would affect coating adhesion<\/li>\n\n\n\n
    • Edge condition:<\/strong> Trimmed square, no burrs or jagged edges<\/li>\n<\/ul>\n\n\n\n

      Mill test certificates per EN 10204 or ASTM B209 are provided with each shipment. <\/p>\n\n\n\n

      Our Guarantees<\/strong><\/p>\n\n\n\n

      Guaranteed 90-degree bending without cracking(H14):<\/strong>\u00a0All sheets supplied for curtain wall applications are tested to withstand a 90-degree bend (inside radius equal to or greater than 1.5x thickness) without any surface cracking, ensuring reliable performance during panel forming and installation.<\/p>\n\n\n\n

      Guaranteed sheet quantity:<\/strong>\u00a0The exact number of sheets specified in the order is delivered. Shortages or overages are strictly controlled, and each package is counted before sealing.<\/p>\n\n\n\n
