There are four types of thickness aluminum alloy sliding windows: series, series, series and series. The series selection should be based on the size of the window opening and the local wind pressure value. Aluminum alloy sliding windows used for enclosed balconies should be no smaller than series.
Strength
The tensile strength should reach millimeter Newtons per square meter, and the yield strength should reach Newtons per square millimeter. When purchasing, you can bend the profile appropriately with your hands, and it should return to its original shape after letting go.
Color
The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to purchase.
Flatness
Check the surface of the aluminum alloy profile. There should be no dents or bulges.
Glossiness
For aluminum alloy doors and windows, avoid purchasing profiles with open bubbles (white spots) and ash (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.
Oxidation degree
The thickness of the oxide film should reach microns. When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.
