Aluminum Window Frame Extrusions & Door Frame Extrusions

beijing build decor exhibition - fonnov aluminium

Aluminum window frame extrusions and aluminum door extrusion are divided into significant frame aluminum profiles and supplemental aluminum profiles. The mainframe aluminum extrusions 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.

Material

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

Thickness

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

Finishing

Anodized Finish

The anodizing surface of the aluminum extrusion for door frame and window frame should have an average film thickness of at least 15μm. You can use the nail to scratch the surface of the door frame and window frame lightly. If the anodizing film can be wiped off, the thickness of the film layer is not up to standard.

Powder Coating & Woodgrain Powder Coating

The thickness of the powder coating on the surface of aluminum extrusions 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 Coating

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.
