      The window frame and sash are both composed of four aluminum corner brackets spliced together, and the connecting fasteners of the four sided profiles are called corner brackets. According to the different levels of window technology, corner brackets are divided into movable corner brackets and expansion glued corner brackets. The selection of expansion glue corner code determines the performance of the system doors and windows and the improvement of the connection performance between the two parts of the door and window profiles.
