Selection Suggestions and Precautions for 3003 Corrugated Aluminum Sheet
Selection Suggestions
Performance Matching
- For high-humidity environments, choose 3003-H24 temper; for coastal areas, PVDF coating is recommended.
- Load-bearing structures require stiffness calculation of wave type. For roof spans ＞6m, strengthened aluminum sheets with wave height ≥35mm are recommended.
Installation Points
- Use concealed clips or self-tapping screws for fastening, spacing ≤300mm, to avoid deformation caused by thermal expansion and contraction.
- Overlap length ≥150mm; sealant at joints must be compatible with aluminum base material to prevent galvanic corrosion.
Cost Optimization
- Bulk purchases can lower unit prices (e.g., discounts of 5–8% for orders over 10 tons), but a 10% allowance for loss should be reserved.
- Compare life cycle costs: initial investment of 3003 aluminum sheet is higher than color steel sheet, but maintenance cost is lower, offering better overall economic performance.
Precautions
Service Environment:
- For buildings in general corrosive environments (such as ordinary atmospheric conditions), 3003 alloy is usually sufficient.
- For harsher environments with higher humidity and stronger corrosion (such as coastal and industrial areas), consider more corrosion-resistant alloys such as 5052 or 5083 aluminum-magnesium-manganese alloys.
Strength Requirements:
- 3003 alloy has higher strength than pure aluminum but lower than 5000 series alloys.
- For higher strength or stiffness requirements (such as large spans or heavy wind/snow loads), consider thicker sheets or higher-strength alloys (such as 5000 series).
Corrugation Type:
Different corrugation types have varying load-bearing capacity, drainage performance, and appearance effects. Selection should be based on structural calculations and architectural design plans.
Surface Treatment:
- Mill finish aluminum: mainly used in anti-corrosion and insulation fields, focusing on corrosion resistance and physical properties.
- Color coating (PVDF, PE, etc.): used for building roofs and walls, providing multiple color options while enhancing weather resistance and decorative effects.
- Anodizing and film covering treatments can provide additional protection or special functions.
