With the application of thermal insulation technology in aluminum alloy profiles, the thermal insulation performance of aluminum alloy doors and windows has been greatly improved, which is one of the main reasons why thermal insulation aluminum alloy doors and windows are favored by more and more builders. In addition, other components of the aluminum alloy door and window system also have different effects on its comprehensive performance. The following is a brief introduction to the influence of hardware on the performance of aluminum alloy doors and windows.
1. The influence of hardware selection on the physical properties of aluminum alloy doors and windows. The durability of physical properties of doors and windows is directly related to the structure and performance of hardware.
After entering the building door and window industry in China, this type of window has been gradually accepted by Chinese people because of its good physical and service performance. The test results show that the air tightness and water tightness of the building doors and windows with this opening mode can reach the first level of the national standard, and the hardware accessories with reasonable structure and perfect functions play an important role. At present, the structure of the hardware and profile system used in China's door and window industry is mostly the same as that in Europe. Its feature is that in addition to the four sides of the window sash can be locked at the same time, the hardware system can realize the three-dimensional adjustment of the window sash relative to the window frame, which can ensure the performance of the door and window in the best state.
2. The impact of hardware on the economic performance of doors and windows. There is also fierce market competition in the construction door and window industry. One of the important ways to get rid of single price competition and create a benign market environment is to continuously enrich product functions and expand product profit space with technical advantages.
And can enrich the door and window product function important link is the hardware fitting. In addition to the above horizontal opening and turning hardware, parallel push-pull upper suspension and lifting push-pull as well as skylight and middle suspension window accessories are new hardware systems introduced into China by Europe in recent years. At the same time, the hardware with the same opening mode has different structural forms to match the corresponding profiles. Products of different materials also provide multiple choices for the market due to their different prices.
3. Hardware selection and production and warehouse management typical hardware parts should not only have good quality, high performance, but also have good versatility.
The same parts can be used in different opening modes of door and window system as far as possible, so as to realize the maximization of the complexity of production process on the basis of ensuring the use function, and facilitate the reasonable flow of inventory goods. This is also a development trend of doors and windows and hardware manufacturing industry in Europe.
4. Hardware is the main factor to determine the quality of the whole window. The surface treatment of hardware affects the service life of the whole window.
According to din50021ss standard, the test results of steinbein surface treatment and Environmental Protection Technology Institute of Germany show that the anti-corrosion performance of the surface coating of door and window hardware is as high as 570 hours, and some iron-based galvanized parts do not even appear white oxide, which provides a reliable guarantee for the service life of the whole window. For the aluminum alloy door and window system, the application of FDS mounting screws from Germany is undoubtedly an effective way to improve the safety performance of doors and windows.
