300mm Thickness Prepainted Aluminum Trim Coil For Drip Edge Producing

 

Product Description

 
Prepainted Aluminum Trim Coil for Drip Edge: Production & Features
 
Prepainted Aluminum Trim Coil for drip edge is a specialized, corrosion-resistant material designed for roofing and construction applications, specifically to protect building edges from water infiltration. Here's a concise technical introduction (≤600 words):

1. Material Composition & Coating Technology

  • Base Material: High-quality aluminum alloy (typically 3003 or 5052 series), chosen for its lightweight, ductility, and natural corrosion resistance. Thickness ranges from 0.25mm to 0.6mm, balancing durability and flexibility for seamless installation.
  • Coating System:
    • Primer: A chromate-free epoxy primer (e.g., zirconium-based) enhances adhesion and corrosion protection, meeting environmental standards (RoHS/REACH-compliant).
    • Topcoat: Polyester (PE) or polyvinylidene fluoride (PVDF, e.g., Kynar 500®) coatings, offering:
      • Color Stability: 200+ standard colors (e.g., matte black, terracotta) with UV resistance (ΔE ≤2 after 3,000+ hours of QUV testing).
      • Weatherability: 10-20+ years of outdoor durability (depending on coating grade), resisting salt, humidity, and temperature extremes (-50°C to 80°C).
    • Thickness: Total dry film thickness 18-25μm (PE) or 25-35μm (PVDF), ensuring scratch and impact resistance.

2. Production Process

  1. Surface Pretreatment:
    • Degreasing → Chemical etching → Chrome-free passivation (e.g., zirconium/titanium salts) to create a micro-rough surface for optimal coating adhesion.
  2. Coil Coating Line:
    • Reverse Roll Coating: Precise application of primer and topcoat using automated lines (speed: 15-30m/min).
    • Curing: Forced-air ovens cure coatings at 180-230°C (PE) or 230-260°C (PVDF), forming a crosslinked polymer matrix.
  3. Slitting & Packaging:
    • Cut to custom widths (100-300mm) for drip edge profiles (e.g., L-shaped, stepped). Coils are wound on steel cores (ID: 406mm) with protective film and waterproof packaging.

3. Key Performance for Drip Edge Applications

  • Waterproofing: The coated aluminum resists rust and water penetration at roof edges, gutters, and fascia boards.
  • Formability: High elongation (≥20%) allows easy bending into drip edge shapes without coating cracking.
  • Thermal Stability: Expands/contracts with temperature changes (CTE: 23.6μm/m·K) without delamination.
  • Fire Safety: Non-combustible aluminum base meets ASTM E136 Class A fire rating.
  • Eco-Friendly: Recyclable aluminum (95%+ recovery rate) and low-VOC coatings reduce environmental impact.

4. Industry Standards & Customization

  • Certifications: AAMA 2603 (PE), AAMA 2605 (PVDF), ISO 12944 (corrosion class C3-C5), and ASTM B209/B221 for alloy quality.
  • Customization:
    • Profiles: Pre-formed drip edge coils (e.g., 270° bend, 15mm flange) for quick installation.
    • Textures: Embossed finishes (woodgrain, stone) for aesthetic roofing designs.
    • Sustainability: Low-carbon production options (e.g., solar-powered lines) for green building projects (LEED credits eligible).

5. Market Applications

  • Residential Roofing: Vinyl, asphalt, or metal shingle edges.
  • Commercial Buildings: High-rise fascia, skylight perimeters, and gutter systems.
  • DIY & Professional Use: Pre-cut coils for contractors (reducing on-site waste by 30%) and DIY kits with color-matched fasteners.
 
Conclusion
Prepainted Aluminum Trim Coil for drip edge combines corrosion resistance, aesthetic versatility, and ease of installation, making it a premium choice for durable roofing. With strict quality control and customizable options, it meets global construction demands while adhering to sustainability goals.

Packaging Requirements for Channel Letter Aluminum coil of Color Coated Aluminum in Marine Transportation

The packaging requirements for High Glossy Black Color Coated Aluminum Channel Letter Aluminum Coil in marine transportation typically involve protecting the coating from damage, preventing corrosion, and ensuring the product remains in good condition during transit. Here are some suggested requirements for the marine transportation packaging of color-coated aluminum:

External Packaging Protection:
High Glossy Black Color Coated Aluminum Channel Letter Aluminum Coil should be placed in sturdy external packaging to prevent impact, compression, or scratching during transportation.
Moisture Prevention Measures:
Consider incorporating moisture-resistant materials in the packaging to prevent the impact of humid conditions on the coating. Humidity can lead to issues such as corrosion and coating peeling.
Cushioning Materials:
Use appropriate cushioning materials such as foam or airbags to mitigate the impact of external shocks on the coating.
Packaging Labeling:
Clearly label the external packaging with information such as the product name, specifications, quantity, and weight.
Add easily recognizable labels, especially indicating situations where the product is sensitive to environmental humidity.
Protective Film:
Use a protective film to cover the color-coated aluminum in the packaging, providing additional protection against dust, pollution, and scratches.
Avoid Deep Stacking:
During transportation and storage, avoid excessive stacking of the coated aluminum coils to prevent deformation, scratches, or coating damage.
Corrosion Prevention Measures:
If High Glossy Black Color Coated Aluminum Channel Letter Aluminum Coil is being transported in a marine environment, consider using corrosion-resistant packaging materials to reduce the impact of marine conditions on the product.
Compliance with Standards:
Adhere to relevant international maritime packaging standards to ensure the packaging meets the requirements for transportation and storage.
Packaging Drawings and Instructions:
Provide detailed packaging drawings and usage instructions to ensure that packaging personnel correctly understand how to pack the coated aluminum coils safely and effectively.
These packaging requirements aim to ensure that High Glossy Black Color Coated Aluminum Channel Letter Aluminum Coil receives proper protection during marine transportation, minimizing the adverse effects of external environmental conditions on the product. Specific packaging solutions may be adjusted based on product characteristics, transportation distance, and mode of transportation.
