AAMA 2605 Powder Coating: What Distributors Should Ask For (and Why It Matters)

Update:2025-12-17
Abstract:

Powder coating is often the hidden difference between a “looks good today” railing and a program that performs for years. Here’s a distributor-focused breakdown of what AAMA 2605 means, what to request from a supplier, and how to reduce coating-related claims in the field.

AAMA 2605 Powder Coating: What Distributors Should Ask For (and Why It Matters)

For exterior aluminum fence and railing programs, coating performance affects everything: long-term appearance, corrosion resistance, and—most importantly for distributors—claim rates and program stability. When you see “AAMA 2605,” treat it as a starting point for verification, not a slogan.

What AAMA 2605 means?

AAMA 2605 is a performance standard commonly referenced for high-performance architectural coatings. For distributors, the takeaway is simple: it sets a higher performance expectation than basic exterior coating claims.

The 5 questions distributors should ask any supplier

  1. Is the coating line automated and process-controlled?
    Controlled lines reduce variation from batch to batch—critical for long-term SKU programs.

  2. What pretreatment process is used?
    Pretreatment is where many coating failures start. Ask for process description and QC checkpoints.

  3. What is the coating spec range (film thickness, gloss, adhesion checks)?
    Distributors should standardize acceptable ranges for program consistency.

  4. What documentation is available for program onboarding?
    Request a coating statement, process summary, and any relevant test documentation.

  5. How do you handle color consistency across repeat orders?
    Program success depends on repeatability. Ask about color control and lot tracking.

 

If your goal is long-term growth, coating isn’t cosmetic—it’s risk management. The supplier that can show process control and documentation is the supplier that protects your brand.
