Aluminum Profiles for Window Frame and Door Frame
Door and window frame aluminium profiles are divided into major frame aluminum profiles and supplemental aluminum profiles. The mainframe aluminium profiles are the basic extruded aluminum that forms the door and window frame. The supplemental aluminium profiles are additional profiles (such as glass beading, water draping, etc.) that are inlaid or fixed to the main aluminium profile bar in the door and window frame to provide force or function.
Door and Window Aluminium Profiles | Material
6000 series aluminium alloy is the main material for aluminium window and door frame. 6063 aluminium alloy is common used for such extruded aluminium profiles.
Door and Window Aluminium Profiles | Thickness
The main force of the aluminium profile for a door is 2.0mm; the thickness of the main force of the aluminium profile for a window is 1.4mm. All parts have a range of tolerance, and the smaller the dimensional tolerance, the better the aluminium profiles are.
Door and Window Aluminium Profiles | Finishing
Anodizing: The anodizing surface of the aluminum profile for door and window should have an average film thickness of at least 15μm. You can use the nail to lightly scratch the surface of the door and window. If the anodizing film can be wiped off, the thickness of the film layer is not up to standard.
Powder Coating: The thickness of the powder coating on the surface of aluminum profiles is at least 40 μm. The coating 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 Finish: The coating is divided into 2-Coat and 3-Coat. The 2-Coat requires an average film thickness of at least 30 μm, and the 3-Coat require an average film thickness of at least 40 μm. The coating on the decorative surface of the profile should be smooth and uniform, and no wrinkles are allowed. , flow marks, bubbling, cracks, etc. affect the defects used.
