The aluminium door accessories and aluminium window accessories are an important part of it. Its performance and quality have an important impact on the function of doors and windows. As the aluminum alloy is easily passivated under natural conditions, the hardware is selected from general metal materials.

Because the service life of hardware has a great influence on the life of doors and windows. Unqualified hardware, doors and windows become empty furnishings.

In the door and window hardware, there is a part which looks inconspicuous, but it has an important link with the door and window opening and closing, sealing, anti-theft - the door and window handle, that is, the door lock handle used on the flat door and window.

We will classify it from the function as follows:

1.Multi-point lock handle

Multi-point lock handle is the most common use of the most extensive hand-held system. By changing the position of the aluminium door handles, a variety of opening functions are realized. The operation is convenient, and the impact resistance is simple. The lock body itself has an encryption function, and it is difficult to emulate and the safety performance is high.

2.Single-point handle

Such as the spinning handle is one kind of single-point handle.

By turning the handle, the window can be opened and closed, and the function locking device can be realized. From the aspect of structure and function, it is relatively simple. By turning the handle, the opening, closing and locking of the actual window can be realized, and a device such as a transmission rod (transmission lock) is not required . It can be understood straightforward for a rotating latch.

3. Linkage handle

The linkage handle is composed of two upper and lower switch locking devices, a linkage linkage mechanism and a handle connected with the lower locking device. Can be locked when plastic sashes are opened or closed. It mainly solves the problems of using a single handle switch sash to cause poor sealing of the upper and lower parts and inconvenient operation with two single handles.
