The allowable deviation of the horizontal frame elevation of windows and doors is 5mm.
The allowable deviation of vertical deviation from the center of windows and doors is 5mm.
The strength of the profile is not enough.
The strength grade of aluminum alloy is divided according to the indexes such as tension, yield, hardness and so on.
The strength is not strong enough to be prone to deformation and damage in severe weather such as typhoon, which is a great threat to the safety of users' lives and property.
Generally speaking, consumers can observe with the naked eye, press with hands, shake and other methods, basically can identify whether the strength of door and window materials is enough.
