Generally, we think that the main components of aluminum alloy doors and windows are glass, door and window frames and hardware accessories. The glass is mostly tempered glass, and the door and window frames are made of aluminum alloy profiles with broken bridge structure. Hardware accessories play an important role in aluminum alloy doors and windows, which are mainly divided into three categories: hardware, sealing materials and auxiliary parts.
The process of opening and closing doors and windows and pushing and pulling doors and windows must be completed with the help of hardware accessories. Not only that, but also the quality of the performance of doors and windows also has a very important impact on hardware accessories.

The opening mode of the sliding door and window is formed by the track and the pulley fixed at the bottom of the door and window leaf. The smoothness of the sliding door depends on the quality of the pulley, the straightness of the profile, the processing accuracy and the fineness of the door and window frame installation.
General sliding doors and windows adopt bolt type lock, which will affect the use effect due to the installation accuracy and surface cleanliness. The handle of sliding door and window is partly replaced by the switch of bolt type lock. Some sliding doors and windows make an arc of window leaf profile to match the flexible use of handle.

One of the accessories of the flat door and window is hinge. The hinge is installed in the open, that is, the inner door and window hinge is installed indoors, and the outer door and window hinge is installed outdoors. In general, door and window lock is usually assembled with a swing lock. The limiter is a necessary component for opening doors and windows to prevent frequent collisions caused by wind. However, the stability level of the fixed plane formed by two hinges and three points of the limiter is limited.
