Corrosion Resistance Aluminum Alloy 5005 For Roofing Sheet
5005 aluminum alloy is widely used for architectural roofing systems, especially in commercial,
industrial, and residential applications where aesthetic appearance, durability, and corrosion re
-sistance are important. Thanks to its excellent surface quality and superior anodizing performance,
5005 is preferred for visible, long-span roofing structures.
Common Tempers
| Temper | Treatment Process | Characteristics & Applications |
| O | Annealed | Softest state; suited for deep forming. |
| H12 | Partially hardened (~25% CW) | Balanced strength/formability (general sheet metal). |
| H14 | Half-hard (~50% CW) | Moderate strength (architectural panels). |
| H32 | Stabilized (H22 + low-temp anneal) | Stress-corrosion resistant (outdoor use). |
| H34 | Hard (~75% CW) | Higher-strength parts (e.g., vehicle trim). |
Performance Advantages of 5005 in Roofing Applications
♦ Excellent Corrosion Resistance
5005 performs well in coastal, industrial, and urban environments, resisting oxidation, acid rain,
and pollution — extending roof lifespan with minimal maintenance.
♦ Superior Anodizing Quality
The alloy allows for uniform, color-consistent anodized finishes, making it ideal for visible archit
-ectural roofing where appearance is important.
♦ Lightweight
Aluminum is significantly lighter than steel, reducing structural load, making it easier to install and
suitable for lightweight framing systems.
♦ Good Strength-to-Weight Ratio
5005 offers enough strength for typical roofing needs while still being easy to handle and shape on-site.
♦ Excellent Formability
Easily fabricated into standing seam panels, corrugated sheets, shingles, and custom profiles, even in
complex curved roof designs.
♦ Non-sparking and Fire Resistant
Aluminum does not produce sparks and has a high melting point, enhancing safety in industrial or high
-risk areas.
