Choosing the right aluminium profile is a critical decision that directly affects project success. Wrong profile selection can lead to installation issues, poor performance and budget overruns. Here are 7 criteria to evaluate when selecting aluminium profiles:
1. Alloy Selection
6060 is suitable for general architectural profiles. 6063 is preferred for decorative profiles requiring high surface quality. 6082 provides high strength in structural systems. Wrong alloy selection shortens profile lifespan.
2. Section Geometry
Profile section determines strength, weight and ease of installation. Complex sections may increase extrusion costs. ICS Aluminium offers extensive range different section options suitable for every project.
3. Surface Treatment
Anodising or Qualicoat-approved powder coating must be used for outdoor profiles. Powder coating is sufficient indoors for cost advantage. Minimum 20-micron anodising is recommended for coastal projects.
4. Thermal Insulation
Thermal-insulated aluminium profiles with polyamide barriers should be preferred for projects targeting energy efficiency. TW50, TW60 and TW76 series offer different Uf values.
5. Tolerance Requirements
Profiles compliant with EN 12020 tolerance classes should be requested for projects requiring precise installation. Standard is ±0.3 mm; ±0.15 mm can be achieved for high-precision projects.
6. Lead Time
Stock profiles can be shipped within the same week, while custom die profiles require 3–6 weeks lead time. ICS Aluminium offers expedited supply options for urgent projects.
7. Quantity and Budget
There is no minimum order requirement for stock profiles. For custom profiles, the minimum quantity to cover die costs is determined on a project basis. Unit price decreases as supply quantity increases.
Conclusion
By evaluating these 7 criteria, you can select the most suitable aluminium profile for your project. When in doubt, the ICS Aluminium technical team offers free consultancy and pricing.
