Production of aluminium profiles for window and aluminium sliding doors is based on our NATIONAL STANDARD GB/T5237-2010. Based on our standard, we provide an aluminium profiles quality certificate for each order on the chemical component, mechanical properties, and finishing test. Our national standard is also workable for the market of the USA and EUROPE.
Material for Aluminium Window Profiles
6000 series aluminium alloy is the primary aluminium profile material for the aluminium window frame. Aluminium alloys 6063 and 6060 are commonly used in FONNOV ALUMINIUM to produce aluminium window profiles. The aluminium billet that we are using is with the national standard.
Thickness of Aluminium Window Profiles
The popular wall thickness of the aluminium profile for a door frame is 2.0mm; the thickness of the aluminium profile for a window frame is 1.4mm. All parts have a tolerance range, and the smaller the dimensional tolerance, the better the aluminium profiles are.
The different market prefers different wall thickness for aluminium window profiles and sliding door profiles. 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.4mm, 1.8mm 2.0mm are available.
Finishing Options for Aluminium Window Profiles
▹Powder Coating & Woodgrain Powder Coating
Powder coating is the most popular finish for aluminium window profiles, especially in residential projects of aluminium windows and aluminium sliding doors. 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 aluminium window profiles and sliding door profiles. Standard exterior and super-durable exterior are used for powder coating finish of aluminium profiles for the window. Some projects close to the sea will prefer super-durable coating.
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.
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.
