Product Description
3003 3004 3005 Durable Color Coated Aluminum Coil Roll for Gutter Systems
The most commonly used and ideal aluminum alloys for manufacturing gutter coils are AA3003, AA3004 and AA3005. Among them, AA3003 is the industry standard and primary choice for gutter applications. AA3003 is a typical heat-treatment-resistant aluminum-manganese alloy with composition approximately: manganese (Mn): 1.0 - 1.5%, copper (Cu): 0.05 - 0.20%, aluminum (Al): remainder.
Material Comparison for Gutter Systems
| Characteristics | AA3003 Aluminum | Galvanized Steel | PVC Plastic | Copper |
|---|---|---|---|---|
| Corrosion Resistance | Excellent (double protection) | Moderate (easily rusted at cuts) | Good (prone to aging and brittleness) | Excellent (forms green copper oxide) |
| Life Expectancy | Extremely long (40+ years) | Medium | Medium | Extremely long |
| Weight | Light | Heavy | Light | Heavy |
| Cost | Medium (initial cost) | Low (initial cost) | Low (initial cost) | Extremely high |
| Life Cycle Cost | Low (no maintenance required) | High (requires painting maintenance) | Medium (requires replacement) | High |
| Aesthetics and Design | Abundant | Limited | Limited | Classic but Singular |
| Environmental Protection | High (infinitely recyclable) | Medium | Medium | High |
From the comparison above, color-coated aluminum sheets represent the optimal choice for downpipe systems, combining superior material properties, performance, and economic benefits.
Materials Science & Corrosion Resistance
This is the primary reason why color-coated aluminum is used for downspouts:
- Natural corrosion resistance: Aluminum forms a dense oxide passivation film when exposed to air, preventing further contact with water and oxygen
- Dual protection coating: Physical barrier and chemical inertness provide complete isolation from water, acid rain, and pollutants
- Optimal alloy selection: Manganese-based alloys (3003, 3004, 3005) maintain excellent corrosion resistance while providing good formability
Surface Treatment & Aesthetics
Downspouts are important visual components that complement building facades:
- Extensive color options: Available in any RAL color range with wood-grain and stone imitation effects
- Long-lasting color retention: High-performance coatings resist UV degradation, maintaining brightness for decades
- Consistent coating quality: Automated roller coating ensures uniform thickness and color consistency
Mechanical Properties & Workability
Gutter coils require specific mechanical properties for roll forming:
- Excellent formability: Alloys in appropriate tempering states (H14, H24) bend into complex shapes without cracking
- Superior strength-to-weight ratio: Lightweight aluminum reduces installation labor and structural load requirements
- Flexibility: Withstands slight collisions and thermal expansion without permanent deformation
Service Life & Life-Cycle Cost
Color-coated aluminum downspouts offer exceptional economic advantages:
- Extended service life: High-quality coated systems last over 40 years with no maintenance
- Low total cost of ownership: Zero maintenance requirements and long lifespan provide the lowest life-cycle cost
Environmental Sustainability
Modern building materials increasingly emphasize environmental attributes:
- 100% recyclable: Aluminum can be infinitely recycled using only 5% of the energy required for new production
- No pollutant emissions: Rainwater flows uncontaminated through aluminum downspouts
