What Is AAMA 2604?

AAMA 2604 is an architectural powder utilized in the finishing of metal surfaces. It is a high-performance coating that offers superior durability, weather resistance, and color retention. This coating is used in the architectural and construction industries to finish metal building components such as window frames, door frames, and curtain walls. There are thousands of applications that you can powder coat, but in general, AAMA 2604 is designed for high-traffic areas.


AAMA stands for the American Architectural Manufacturers Association, a trade association that develops and publishes standards and guidelines for the architectural and construction industries. In 2020, the AAMA and IGMA (The Insulating Glass Manufacturers Alliance) unified as the FGIA – The Fenestration and Glazing Industry Alliance. AAMA 2604 is one of the standards developed by this association, which specifies the requirements for organic coatings applied to architectural aluminum extrusions and panels.

Superior resistance against harsh weather conditions

One of the main benefits of AAMA 2604 powder coating is its superior durability. This coating can withstand the harsh outdoor environments in which building components and outdoor equipment are exposed, such as rain, wind, and sunlight. It is also resistant to chalking, fading, and cracking, which helps maintain the coated surface's appearance over time.

Enhancing Your Building

Another benefit of AAMA 2604 powder coating is its excellent weather resistance. This powder coating resists damage from UV radiation, salt spray, and other environmental factors that can cause corrosion and degradation of metal surfaces. It also provides good resistance to chemicals and solvents, which helps to protect the underlying metal from corrosion and other forms of damage.

Excellent Color Retention

AAMA 2604 powder coating is also known for its excellent color retention properties. This coating maintains its color and gloss over time with colors that match any facade or application. AAMA 2604 ensures that the building components look pristine for many years, even in harsh outdoor environments.

Architectural Powder Coating Process

All metal is processed similarly through our state-of-the-art Power Coating Paint line. It starts with a 5-stage wash system that provides surface pretreatment for corrosion protection, paint adhesion, and salt spray. After going through a dry oven to ensure a thoroughly dry surface and that no moisture remains on the surface, it proceeds to our automated paint room. The powder is applied using an electrostatic spray process automatically. Manual stations are also used depending on the specific item. The coating is applied as a dry powder and baked at high temperatures to cure and form a hard, durable finish. This process helps to ensure that the coating adheres well to the metal surface and provides excellent coverage and protection.
