The specification size of aluminum alloy door and window profile is mainly marked by the height size of the profile section (used in aluminum alloy doors and windows to call it the thickness size of the door and window frame) and forms a size series. Aluminum Alloy door and window profile can be 40, 45, 50, 55, 60, 65, 70, 80, 90, 100mm and other size series. Among them, the size series used for aluminium windows is relatively small, while the size series used for aluminium alloy door is relatively large. Aluminum doors and windows are marked with the same size series, not necessarily aluminum alloy door and window profile of the cross-sectional shape and size are the same. The cross-sectional shape and size of aluminum alloy door and window profile of the same size series are quite complicated. It must be analyzed and treated according to the pattern.
Aluminum Alloy door and window profile according to the cross-sectional shape, it is divided into solid profiles and hollow profiles, and the application amount of hollow profiles is relatively large.
The wall thickness of aluminum alloy door and window profile is not less than 1.4mm for aluminium windows, and the aluminum alloy door is not less than 2mm.
The length and size of aluminum alloy door and window profile are divided into three types: fixed ruler, double ruler and irregular ruler. The length of the fixed ruler is generally not more than 6m, and the length of the irregular ruler is not less than 1m.
