In home decoration, sometimes the aluminum alloy doors and windows may not be opened normally due to some reasons after the installation of doors and windows is completed. Boshi home doors and windows will share with you the reasons:
the first reason may be that when installing, the horizontal and vertical directions are not controlled, resulting in the aluminum alloy doors and windows being twisted and tilted, and finally the aluminum doors and windows fan cannot be opened normally. If there is sun visor on the doors and windows, too much concrete will be used in the construction process, which will cause the formwork supported by the concrete to be too low.
The second reason is that if the window frame of aluminum alloy doors and windows is too thick, the aluminum alloy window frame will be pressed against the hinge of aluminum alloy doors and windows, which will make the aluminum doors and windows fan unable to open.
Here, by the way, what should be paid attention to during the installation process? The key is that the operation must be standard. Make sure that the aluminum alloy doors and windows are horizontal and vertical, and do not skew. It is better to fix them well. If there is a concrete sun visor, the bottom template should be higher than the frame of the door and window.
