Alloy 3004 0.25mm Prepainted Aluminium Coil for Train Window Frames

Alloy 3004 0.25mm Prepainted Aluminium Coil for Train Window Frames
Alloy 3004 0.25mm Prepainted Aluminium Coil is engineered for high-performance train window frames, combining lightweight durability with exceptional corrosion resistance. This alloy features a manganese-magnesium composition (3004 temper H112), providing superior strength compared to standard alloys like 3003 7. The 0.25mm thickness ensures optimal formability for complex frame designs while maintaining structural integrity. Pre-painted with PVDF or PE coatings (16–25μm thickness), it offers UV resistance, weatherproofing, and color retention in harsh environments 26. Ideal for transportation applications, it meets rigorous standards for fire safety, impact resistance, and low maintenance 81, ensuring long-term reliability in railway systems.

Key advantages include:

  1. Efficient heat dissipation performance
  2. Lightweight and durable construction
  3. Corrosion-resistant coated surface
  4. Cost-effective thermal solution
  5. Easy fabrication and installation
  6. Long-lasting performance stability
  7. Environmentally friendly materials
  8. High-temperature resistance coating
  9. Enhanced surface aesthetics  
  10. Optimized for electronics cooling needs

 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.
