The number of series represents the number of millimeters of the thickness and structure of the door frame. There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The selection of series should be determined based on the size of the window hole and the local pressure value. The aluminum alloy sliding window used as a sealing platform should be no less than the 70 series.
2.Strength
Tension strength should reach 157 nunton per square meter mm, and yield strength should reach 108 nunton per square meter. When purchasing, you can use hand-fitting curved profiles, which can restore the state after releasing.
3. Color level
The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not advisable to choose.
4. Flatness
Check the surface of the aluminum alloy profile, and there should be no depression or bulge.

2. Good performance, especially good sealing. Its air density, watertightness and sound insulation are better than ordinary doors and windows. Therefore, aluminum alloy doors and windows are more suitable for buildings that install air conditioning equipment and buildings with special requirements for dust prevention, sound insulation, and heat insulation.

The aluminum alloy doors and windows have high strength, good performance, durability, and the parts will not be damaged for a long time. They are flexible and easy to open and have no noise.
5. Convenient to conduct industrial production. The processing, production, decoration and trial of aluminum alloy doors can be carried out in the factory, which is conducive to the implementation of product design standardization and serialization, universal spare parts, and commercialization of products.
