1, hardware according to product classification
Aluminum alloy doors and windows accessories are classified by product: transmission mechanism with handles, screwed handles, hinges (hinges), transmission locker, slide brace, brace block, pin, multi-point locker, pulley, single-point locker and flush under-hung hardware, etc.
2、Classification according to the use
Aluminum alloy door and window fittings are classified into door hardware and window hardware by category. According to the use can be divided into sliding door and window hardware, casement window hardware, internal casement under-hung window hardware accessories.
(1) sliding doors and windows: aluminum alloy doors and windows are directly formed on the window frame profile, and the pulley system is fixed at the bottom of the door and window sash. The flexibility of sliding doors and windows not only depends on the quality of the pulley flush, but also on the straightness and processing accuracy of the profile and the accuracy of the window and door frame installation. Dust accumulation on the track and pulley wear and tear will also affect the sliding doors and windows open and close function. The locks of sliding doors and windows are generally latch-type locks, which can affect the effective use of their functions due to poor installation accuracy and dust accumulation. Sliding door and window handle is usually replaced by the switch part of the latch type lock, but there are also higher sliding windows will make an arc window profile to match the flexible use of the handle.
(2) ordinary casement windows: one of the accessories of casement windows is the hinge.

The stopper is a necessary part of an exterior window or door to prevent the wind from blowing the door or window sash around and bumping it frequently. However, the stability level of the fixed plane formed by two hinges and three points of the restrictor is limited.
(3) Inner casement under-hung window: The hardware of inner casement under-hung window contains top scissor connector, corner connector, lock, handle, connecting rod, multi-point lock, lower corner connector and bottom shaft of under-hung window, bottom hinge and bottom shaft of inner rotation. The inner flush down-hung window is a window that can both hang down and open inward and may open inward, but it is much more than that; at heart, it is a summation of various window control functions. First of all when this window is tilted inward, the purpose is to change the air. The top shear connector acts as a restrictor, and from the inside flush start, the top shear connector is a hinge, and the bottom hinge is at the same time a shaft for the inside overhang. In addition to meeting the view of the window, more importantly, it is easy to wash the glass.
