The doors and windows made in this way are called plastic-steel doors and windows.

[0003] When installing plastic-steel doors and windows, first clean the dust and mud on the windowsill, use a tape measure to measure whether the width and height of the windowsill are consistent with the size of the window frame, then place the window frame on the windowsill, and use a tape measure to measure whether the distance between the window frame and the edge of the windowsill is consistent, so as to make sure that the window frame is installed flat, and then fix the window frame to the windowsill with expansion screws, and then apply sealant to the edges of the window frame and windowsill to seal, wait for the sealant to dry, and finally install the window sash in the groove of the window frame.

[0004] While waiting for the sealant to dry, the wind may cause mud and sand to enter the grooves on the window frame, which can easily clog the drainage holes and affect the installation of the window sashes. It is necessary to use a protective plate to protect the grooves. Utility Model Content
