Aluminum alloy doors and windows are favored by more and more people, so how to choose the material of aluminum alloy doors and windows, I will talk to you here:   1. Thickness: There are 70 series and 90 series for aluminum alloy sliding doors. The 70 series is sufficient for alloy sliding doors. The series number indicates the millimeter of the thickness 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 the series should be determined according to the size of the window and the local wind pressure. The aluminum alloy sliding window used to close the balcony should not be less than 70 series.  2. Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can use your hands to moderately twist the profile, and it should be able to recover after letting go.  3. Chroma: The color of the same aluminum alloy profile should be the same. If the color difference is significant, it is not suitable for purchase.   4. Flatness: Check the appearance of the aluminum alloy profile, there should be no depression or bulging.  5. Glossiness: Aluminum alloy doors and windows prevent the purchase of profiles with obvious defects such as open bubbles (white spots) and slag (black spots) on the outside, as well as cracks, burrs, and peeling.  6. u200bu200bDegree of oxidation: The thickness of the oxide film should reach 10 microns. When purchasing, you can cut off the surface of the profile lightly to see if the oxide film on the surface can be wiped off.
