There are six main aspects of materials for reference:
Thickness
There are 70 series and 90 series in aluminium alloy sliding door, and 70 series can be used for aluminium alloy sliding door inside the house. The number of series indicates the number of millimeters of the door frame thickness construction dimension. Aluminium alloy sliding window has four types: 55 series, 60 series, 70 series and 90 series. Series selection should be based on the size of the window hole and the local wind pressure value. The aluminium alloy sliding window used as a closed balcony shall not be less than 70 series.
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 bend the profile moderately, and you should be able to recover after loosening your hands.
Chromaticity
The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable to buy.
Flatness
Check the surface of aluminum alloy profile, there should be no depression or bulging.
Gloss
Aluminum alloy doors and windows avoid choosing 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
Oxide film thickness should reach 10 micron. When purchasing, you can draw the profile surface lightly to see if the oxide film on the surface can be wiped off.
