    Alloy 3004 0.65mm Prepainted Aluminium Coil for Railway Carriage Ventilation Grilles

    Alloy 3004 0.65mm Prepainted Aluminium Coil for Railway Carriage Ventilation Grilles

    Engineered for demanding railway environments, this 0.65mm Alloy 3004 prepainted coil combines lightweight strength with exceptional corrosion resistance. The manganese-enhanced alloy delivers robust mechanical properties (tensile strength: 140-180 MPa), ensuring structural integrity in high-vibration settings. Pre-coated with high-performance PVDF or polyester finishes , it provides superior weather resistance, UV stability, and color retention for long-term exterior use. Ideal for ventilation grilles, its formability allows intricate shaping while maintaining rigidity . The coil’s uniform coating thickness (~16–25μm) guarantees consistent aesthetics and durability, reducing maintenance costs throughout the rail carriage lifecycle.


    Key advantages include:

    1. High Strength-to-Weight Ratio
      Lightweight yet structurally robust .

    2. Superior Corrosion Resistance
      Withstands humidity, chemicals, and harsh environments .

    3. Excellent Formability
      Easily shaped into complex grille designs without cracking

    4. Durable Pre-coated Finish
      PVDF/PE coatings resist fading, scratches, and UV degradation.

    5. Low Maintenance Requirements
      Retains appearance and function with minimal cleaning .

    6. Fire Safety Compliance
      Meets railway flammability and smoke toxicity standards .

    7. Cost-Effective Production
      Reduces fabrication time and finishing costs .


    Application


    About Prepainted Aluminum Coil


    Prepainted aluminum coil, which is produced with aluminum sheet or (aluminum coil) and processed by coating with color. In common sense,

    there are two kinds of prepainted aluminum coil-PVDF and PE, which are widely used in aluminum plate, aluminum veneer, aluminum

    honeycomb panels,aluminum ceiling, shingles, scrap, pop-top, electronics.


    PVDF coatings are known for their durability and weather resistance. They provide a smooth and glossy finish, making them suitable for

    architectural applications. PVDF coated aluminum coils are available in a wide range of colors and are often used for exterior cladding,

    roofing, and signage.


    PE coatings offer good UV resistance and color retention. They are commonly used for interior applications where extreme weather

    resistance is not required. PE coated aluminum coils are available in a variety of colors and are used for indoor decorations, ceiling panels, and more.

    Product Advantages

    1.High flatness: the surface is flat and smooth, without obvious defects such as unevenness, wavy deformation, indentation or bulging.
    2.Uniformity of colour: The colour is uniform and consistent, with no obvious colour difference.
    3.Strong coating adhesion: good adhesion between the coating and the aluminium coil substrate makes it difficult for the coating to flake, peel or lose paint.
    4.Good weather resistance: PVDF coatings have a colour stability of more than 20 years compared to 10-15 years for polyester coatings. 5.Strong corrosion resistance: The natural oxidation layer of aluminium combined with a protective coating such as PVDF ensures long term durability in harsh environments.
    6.Malleability: complex bending and forming without cracking.
