Usually, we are often misled by the "matching" of accessories. Over time, we form the misunderstanding that door and window hardware is a "supporting role". Our understanding of door and window hardware accessories is only a secondary and ineffective thing.

Some manufacturers have a vague understanding of the main role of door and window hardware accessories and do not pay attention to them. When designing, the grid size is often too large, or unnecessary weight is added to the window, or even the configuration of hardware accessories is changed at will, resulting in wind pressure resistance, Insufficient water-tightness and air-tightness may lead to accidents such as air leakage, rain leakage, or even falling off.

Door and window accessories (locks, pulleys, hinges, handles, sliding stays, etc.) are key components that determine the performance of doors and windows. The design of aluminum alloy doors and windows is first of all the architectural design of door and window performance to meet the functional requirements of the building. The goal is to reasonably determine the performance and related design requirements of aluminum doors and windows.

When designing doors and windows in a building, the aesthetics of the entire house and the area's wind pressure resistance, water tightness, air tightness, thermal insulation, heat insulation, sound insulation and other properties are considered. Just imagine, based on the physical properties of doors and windows (wind pressure resistance, water tightness, air tightness, sound insulation, thermal insulation, heat insulation, etc.) and mechanical properties (opening and closing force, repeated opening and closing), which one is better than the doors and windows? Doesn't it matter if the hardware accessories?

Hardware accessories are responsible for tightly connecting the frames and sash of doors and windows. Without it, doors and windows will only become dead sash, and the meaning of doors and windows will be lost. Let’s analyze the role of hardware accessories on doors and windows from the performance and functions of doors and windows:

1、Physical performance indicators of doors and windows.

The physical performance indicators of doors and windows include: wind pressure resistance, air tightness, water tightness, thermal insulation, heat insulation, sound insulation, and wind pressure resistance.

When the inner casement window is subject to positive wind pressure: the hardware locking points are stressed, so it is advisable to adopt a multi-locking point form. The more locking points there are, the smaller the force exerted by each locking point on the center stiffener, and the smaller the deformation relative to the deflection. When the inner casement window is subjected to negative pressure: the frame is stressed.

When the external casement window is under pressure: the locking point is stressed, so it is advisable to adopt a multi-locking point form. The more locking points there are, the smaller the force exerted by each locking point on the center stiffener, and the relative deflection of the deformation will be smaller.

When an external casement window is subject to positive wind pressure: the frame is stressed.

To sum up, the role of hardware accessories on the wind pressure resistance, the primary performance of doors and windows, determines the success or failure of doors and windows; similarly, air tightness, water tightness, thermal insulation, heat insulation, and sound insulation are all related to the doors and windows in which hardware accessories are involved. About sealing. Hardware lock points and lock seats are distributed around the entire door and window. When the door and window are locked, the lock point and lock seat are firmly buckled together, and cooperate with the hinge (hinge) or sliding brace to jointly generate a strong sealing pressure, causing the sealing strip to elastically deform, thereby providing the door and window with sufficient sealing force. Sealing performance, integrating the sash and frame can greatly improve the performance of doors and windows. Similarly, opening and closing requirements such as door and window folding mechanical performance indicators (opening and closing force, repeated opening and closing performance) are also inseparable from the requirements of hardware accessories.

2、The key to thermal insulation of doors and windows.

Doors and windows are lightweight components, and their energy consumption accounts for more than half of the building's energy consumption. They are the top priority for building energy conservation. When designing, the energy-saving issues of doors and windows must be fully considered, that is, thermal insulation and thermal insulation. If there are no multi-point lock hardware accessories, no matter how good the doors and windows are, their thermal insulation and heat insulation properties can be imagined.

3、Anti-theft.

The anti-theft performance of doors and windows is also the most sensitive and concerning issue in home life. In this regard, the anti-theft performance of hardware accessories plays an important role, especially in the development of components for smart anti-theft doors and windows.

4、Functional application and play of doors and windows.

Doors and windows have a variety of window shapes and structural forms, and the various functions of the window type all depend on the configuration of hardware accessories. Without hardware accessories, how can a casement-opening bottom-hung window achieve the functions of both casement-opening and inward-turning? How to achieve both sliding and folding functions in sliding and folding doors and windows? Internal push-pull, movable louvers, etc. all rely on hardware accessories to achieve unique and specific functions.
