Quality parameters of aluminum alloy profiles

    1. aluminum alloy profile strength: tensile strength should be up to 157 Newton per square meter of 157 millimeters, yield strength to 108 Newton per square millimeter. When choosing, you can use the hand to bend the profile properly. After the pine hand, it can see if it can be restored to the original shape.

    2. aluminum alloy profile color: the color of the same aluminum alloy profile should be the same, if its color difference is obvious, then do not choose.

    3. aluminum alloy profile Flatness: check the surface of aluminum alloy profiles, aluminum alloy profiles should not be sunken or drums.

    ​4. aluminum alloy profiles: aluminum alloy profiles, avoid bubbles and ash on open surfaces, as well as obvious defects such as cracks, burrs or shedding.
