HJD HARDWARE is a factory with 31 years of production experience and 21 years of export experience.Today let me tell you how to choose hardware.Without good profiles as the cornerstone, no good doors and windows can be made with any kind of hardware.The selection of profiles and hardware should be considered comprehensively. Don't choose the profile and then choose the hardware. This situation sometimes leads to the lack of matching hardware due to non-standard profiles.
The key to determining the performance of doors and windows
Hardware accessories are the key components that determine the performance of doors and windows. The design of aluminum doors and windows is first of all the architectural design of the performance of doors and windows, to meet the functional requirements of the building as the goal, and reasonably determine the performance and related design requirements of aluminum doors and windows. When designing doors and windows in buildings, it is considered from the beauty of the whole house and the areas where it is located, such as wind resistance, water tightness, air tightness, heat preservation, heat insulation, and sound insulation. Hardware accessories are the parts responsible for tightly connecting the frames and sashes of doors and windows. Without it, the meaning of doors and windows would be lost.
1. Three major components of hardware accessories
lOperating parts
The handle of the operating parts is used for opening doors and windows every day. If it is not firm and the surface is damaged, the shaking gap is large, the hand feel is poor, the installation fixing screws are loose or falling off, the handle is loose, or even the fixing feet are broken, which will affect the service life of the doors and windows. According to industry standards, the service life of the anti-corrosion and anti-rust treatment of hardware is 10 years, which is enough to meet the use of normal building doors and windows. Good hardware should look thick, and the surface gloss should be good, the protective layer should be dense, no scratches, the most important point is that the opening should be flexible.
lLocking parts
The locking parts mainly include transmission parts such as lock points, lock buckles, actuators, and angle gears. The use of these accessories plays an important role in the physical performance of doors and windows, and they need to be anti-theft when they are locked. This requires hardware accessories to be firmly embedded in the profile, and only when they are firmly combined with the profile can they achieve the anti-theft function.
lFrame and fan connection load-bearing parts
Connecting load-bearing parts mainly include hinges, friction stays, and rollers. The selection of this component is particularly important, and it is related to the performance, safety, and life of doors and windows.
In terms of functionality, the hinge is an important part to realize the rotation and load-bearing of doors and windows. It is mainly used for inner casement windows and flat doors. Its firmness and anti-theft performance are the same as locking parts.
Friction Stay are applied to external casement windows and curtain wall external suspended windows. As the windows open outwards, the load-bearing requirements of the height, width and weight of the fan should be considered, and friction stay of the corresponding load-bearing level should be selected.
Rollers are used for sliding doors and windows. Realize the sliding movement function of doors and windows. Just select the corresponding load-bearing level.
