For home, a beautiful set of furniture and a wonderful design are not as good as a high-quality external window. The hardware in the whole door and window system plays an important role in its performance.

First, affect the physical properties of doors and windows

The durability of physical properties of doors and windows is directly related to the structure and performance of hardware. After the flat-opening rotary window entered the building door and window industry in China, this window type has been gradually accepted by Chinese people because of its good physical and use performance. The test results show that the air tightness and water tightness of the open building doors and windows can reach the first-class level of the national standard. At present, the structure of this hardware and profile system used in the door and window industry in China is mostly the same as the current system in Europe. Its characteristic is that the four sides of the window sash can be locked at the same time, and the hardware system can realize the three-dimensional adjustment of the window sash relative to the window frame, ensuring the best performance of the doors and windows to the greatest extent.

Second, affect 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 single price competition and create a benign market environment is to continuously enrich product functions and expand product profit space with technological advantages. The important link that can enrich the functions of doors and windows products is hardware accessories. In addition to the above-mentioned flat turnover hardware, parallel push-pull hanging and lifting push-pull and skylight and middle hanging window fittings are all new hardware systems introduced from Europe to China in recent years. At the same time, the hardware with the same opening mode has different structural forms to match the corresponding profiles, and products with different materials also provide multiple choices for the market because of their different prices.

Third, affect the life of the whole window

The quality of hardware also affects the service life of doors and windows. Generally speaking, the service life of anti-corrosion and anti-rust hardware is 10 years, which is enough to meet the needs of normal building doors and windows. Experts pointed out that good hardware should look thick, and the surface gloss is good, the protective layer is dense, and there is no scratch. The most important thing is that it should be flexible to open.
