Aluminum Profiles for Window Frame and Door Frame

beijing build decor exhibition - fonnov aluminium

Door and window frame aluminium profiles are divided into significant frame aluminum profiles and supplemental aluminum profiles. The mainframe aluminum profiles are the primary 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 primary aluminum profile bar in the door and window frame to provide force or function.

Door and Window Aluminum Profiles | Material

6000 series aluminum alloy is the primary material for aluminum window and door frame. 6063 aluminium alloy is common used for such extruded aluminium profiles.

Door and Window Aluminum Profiles | Thickness

The main force of the aluminium profile for a door is 2.0mm; the thickness of the main effect of the aluminum profile for a window is 1.4mm. All parts have a range of tolerance, and the smaller the dimensional tolerance, the better the aluminum profiles are.

Door and Window Aluminum 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 scratch the surface of the door and window lightly. 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 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. Woodgrain color is also a kind of powder coating surface, but with a wood-like texture and color.

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 requires 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.
