Finishing Options for Aluminum Window Extrusion Profiles
▹Powder Coating & Woodgrain Powder Coating
Powder coating is the most popular finish for aluminum window extrusion profiles, especially in residential projects of aluminium windows. It brings a durable finish with a wide range of colour options. White, black, brown, grey, and beige are the most popular powder coating colours for aluminum window extrusion profiles. Standard exterior and super-durable exterior coatings are usually used for aluminum window extrusion profiles. Some projects close to the sea will prefer super-durable coating for aluminum window profiles.
Wood finish is based on the powder coating process. It provides a timber look and makes the aluminum frame looks like wood. A wide range of wood colours is available in FONNOV ALUMINIUM.
The thickness of the powder coating on the surface of aluminum window extrusion profile is at least 40 μm, and the standard thickness should be 60-80um. The layer on the decorative surface of the profile shall be smooth and uniform, and no defects such as wrinkles, flow marks, bubbling, or cracks shall be allowed.
Some landmark commercial projects prefer PVDF coating for aluminum window extrusion profiles, which can provide a more extended warranty than powder coating. The coating can be 2-Coat and 3-Coat. The 2-Coat requires an average film thickness of at least 30 μm, and the 3-Coat requires at least 40 μm. The coating on the decorative surface of the profile should be smooth and uniform, and no wrinkles, flow marks, bubbling, or cracks are allowed.
