With the application of thermal insulation technology on aluminum alloy profiles, the thermal insulation properties of aluminum alloy doors and windows have been greatly improved, which is one of the main reasons why insulated aluminum alloy doors and windows are favored by more and more builders. In addition, the other components of the aluminum alloy door and window system also have different effects on its comprehensive performance. The following is a brief introduction from the impact of hardware on the performance of aluminum alloy doors and windows.
1. The influence of the selection of hardware on the physical properties of aluminum alloy doors and windows has a direct relationship with the durability of the physical properties of the doors and windows and the structure and performance of the hardware. After the swing open window enters the door and window industry of China, due to its good physical and performance properties, this window type has gradually been accepted by the people. The test results prove that the airtightness and watertightness of the building doors and windows of this kind of opening mode can reach the national standard level, and the hardware components with reasonable structure and perfect function play a vital role. At present, the structure of such hardware and profile systems used in China's door and window industry is mostly the same as the current system in Europe. The feature is that in addition to the four sides of the sash can be locked at the same time, the hardware system can realize the three-dimensional adjustment of the sash relative to the window frame, and the maximum performance of the door and window is guaranteed to the best.
2. The impact of hardware on the economic performance of doors and windows There is also fierce market competition in the building door and window industry. One of the important ways to get rid of the single price competition to create a benign market environment is to continuously enrich product functions and expand product profit margins with technological advantages. The important part that can enrich the function of door and window products is hardware accessories. In addition to the above-mentioned flat-turning hardware, the parallel push-pull up-and-hanging and lifting push-pull and skylight and mid-hung window fittings are all new hardware systems introduced into Europe by Europe in recent years. At the same time, the hardware of the same opening method has different structural forms and corresponding profiles, and the products of different materials also provide multiple choices for the market due to their different prices.
3, hardware selection and production and storage management typical hardware not only good quality and high performance should also have good versatility. The same components are used for the door and window system of different opening methods as much as possible, so that the complexity of the production process can be maximized on the basis of ensuring the use function, and the stock goods can be reasonably flowed at the same time. This is also a development trend in European door and window and door and window hardware manufacturing.
4. Hardware is the main factor determining the quality of the whole window. The surface treatment of the hardware affects the service life of the whole window. The test results of the Stanbyin Surface Treatment and Environmental Technology Institute in Germany according to the DIN50021SS standard show that the surface coating corrosion resistance of the door and window hardware is as high as 570 hours, and some iron-based galvanized parts do not even appear white oxide, which is the whole window. The service life provides a reliable guarantee. For aluminum alloy door and window systems, the application of the current FDS mounting screws from Germany is also an effective way to improve the safety of doors and windows.
