What is AAMA 2605?
What is AAMA 2605?
The AAMA (American Architectural Manufacturer’s Association) has developed 3 standards by which architects and designers can easily identify the differences between finish performance on metals:
- AAMA 2603 = Good performance
- AAMA 2604 = High performance
- AAMA 2605 = Superior performance
Metal panels include 2 major parts, the substrate and the finish. While the finish color itself might be the seemingly most important feature of the panel, it actually is not. Nearly any hue, pattern, gloss, or texture can be achieved with certain metals and specific paint processes, but the longevity of the finish itself is the true key to specification.
These standards measure the finish on a variety of factors, including:
- Dry film thickness
- Humidity resistance
- Cyclic corrosion
- Color retention
- Chalk rating
- Gloss retention
- Coating erosion
- Outdoor weather exposure testing (South Florida 10-Year Test)
The key to achieving the highest rating of 2605 is passing the South Florida 10-Year Test. Panels must be exposed to the South Florida environment for 10 years before the other readings can even take place!
Finishes that meet the 2605 rating offer designers, and subsequently building owners, a low-maintenance solution for exterior cladding. This rating also ensures that the materials designers specify today will not differ in appearance in a few short years, especially for those installed in harsh climates. Opting for AAMA 2605 finishes during each specification, especially over natural materials, ensures a legacy of maintenance can be entirely avoided.
Pure + FreeForm materials are all AAMA 2605 rated for Superior Performance for Exterior Coatings. Coupled with a 20-year warranty, our finishes bridge the gap between beauty and performance. To see our AAMA 2605 testing results, check our Product Facts page and download our full report!

AAMA 2605 Aluminum Finishes
At Pure + FreeForm, all finishes meet AAMA 2605 standards, ensuring superior performance across architectural applications. Fabricated on Ultra High Performance Aluminum™, these finishes are designed to maintain color, gloss, and surface integrity over time while resisting corrosion and environmental wear.
This allows architects and designers to specify high-performance metal finishes with confidence, achieving both long-term durability and consistent visual results across interior and exterior applications.
Why AAMA 2605 Matters in Architecture
AAMA 2605 is critical for ensuring long-term building performance. Coatings that meet this standard provide:
- Exceptional resistance to UV radiation and color fading
- Protection against corrosion and environmental damage
- Long-term gloss retention and surface integrity
- Reduced maintenance over the life of the building
These benefits make AAMA 2605 ideal for façades, soffits, wall panels, and other exterior metal applications where longevity is essential.
AAMA 2605 and Pure + FreeForm Finishes
Applied to Ultra High Performance Aluminum™, our finishes are designed to resist fading, chalking, corrosion, and environmental exposure, delivering long-term durability with minimal maintenance. This level of performance allows architects and designers to specify finishes with confidence, knowing the material will perform as intended for years to come.
Beyond performance, Pure + FreeForm finishes offer a wide range of design possibilities. From metal and patina-inspired tones to woodgrain and custom-developed finishes, each option meets AAMA 2605 standards while supporting a cohesive architectural vision across walls, ceilings, façades, and custom applications.
Frequently Asked Questions
AAMA 2605 is the highest performance standard for coatings on architectural aluminum, ensuring superior durability, color retention, and resistance to environmental exposure.
AAMA 2605 indicates that a coating meets the most rigorous testing requirements for long-term exterior performance, including resistance to fading, chalking, and corrosion.
AAMA 2605 ensures that architectural metal finishes maintain their appearance and performance over time, reducing maintenance and improving long-term building durability.
AAMA 2605 requires more rigorous testing and longer weather exposure than AAMA 2604, making it better suited for long-term exterior applications.
