The standard thickness of aluminum profile doors and windows is not less than 1.20mm.
Aluminum alloy doors and windows are made of aluminum alloy extruded profiles for frames, handles, and fan materials. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows made of aluminum alloy as a force rod (a rod and load that bears and transmits its own weight) as a base material and wood and plastic composites, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows.
The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), aluminum material surface treatment and internal processing quality, aluminum alloy doors and windows, etc.
Extended information:
Aluminum alloy door and window profiles mainly include: 35 series, 38 series, 40 series, 60 series, 70 series, 90 series, etc.
The so-called 35 and 38 refer to the width of the main aluminum frame being 35mm and 38mm respectively.
The size of aluminum door and window profiles is mainly marked by the cross-sectional height dimension of the profile (called the thickness dimension of the window frame on aluminum doors and windows), forming a size series. The size series of aluminum alloy doors and windows is relatively small, while the size series of aluminum alloy doors and windows is relatively large. The size series of aluminum doors and windows are the same, but the cross-sectional shape and size of the profiles may be different.
