The aluminium profiles for the window are aluminium window profiles or aluminium window frame extrusions. They can be used to fabricate aluminium sliding windows (vertical and horizontal), aluminium sliding doors, aluminium casement windows, hung opening windows, tilt and turn opening windows, and aluminium folding doors. Not only are the mainframes for aluminium windows and sliding doors. We also produce supplemental aluminium profiles for glass beading and water draping that are inlaid or fixed to the frames.

Wood finish is based on the powder coating process. It provides a timber look and makes the aluminium 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 aluminium extrusions 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.

▹PVDF Coating

Some landmark commercial projects prefer PVDF coating for aluminium window 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.
