Al-Mg Series 5005 Aluminum Alloy Sheet 5005 Aluminum Sheet For Roofing
5005 aluminum alloy belongs to the Al-Mg series (5xxx series) of rust-proof aluminum alloys. It
offers excellent corrosion resistance, moderate strength, and good workability, making it widely
used in construction, decoration, transportation, and other industries.
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). |
| H34 | Hard (~75% CW) | Higher-strength parts (e.g., vehicle trim). |
Performance Advantages 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.
♦ Non-sparking and Fire Resistant
Aluminum does not produce sparks and has a high melting point, enhancing safety in industrial or high
-risk areas.
Typical Applications
♦ Commercial and public building rooftops (airports, stadiums, schools)
♦ Modern residential housing roofs (especially in coastal areas)
♦ Long-span industrial warehouse roofing
♦ Lightweight modular roofing systems
♦ Curved, architectural roof designs
