What we see in Baidu query is basically the promotion staff of some brand enterprises promoting themselves, basically 9 big brands, and then one or two small brands, these two small brands are the people who send these promotion enterprises. Therefore, the credibility is greatly reduced. So we looked for it on GOOGLE again. Top ten famous brands of doors and windows, the query results you see are different, and the basic credibility is greatly improved.
We can see that some netizens said that the conditions for evaluating the top ten brands must have at least the following characteristics:
1. Decorative doors and windows
2. Insulation doors and windows
3. Sound insulation doors and windows
4. Ultra-low cost doors and windows
5. Electronic control doors and windows
Some people say that today's doors and windows are like computer assembly machines. Glass manufacturers provide glass (the quality of glass varies greatly), while door and window factories take goods by door & window profile such as fengaluminum and guangaluminum, take Back the profiles of Phoenix aluminum and guangaluminum, find matching rubber strips and hardware accessories in the market, and then assemble them as doors and windows. I don't think this is a brand, which is more in line with the name of door and window assembly factory/door and window assembly shop.
The so-called door and window brand is to open the mold and customize the aluminum with some aluminum factory, and use the domestic hardware accessories factory to reach an agreement with them to customize the hardware accessories. Glass is still produced by the glass factory. The lower the cost, the better. The appearance is high-end, elegant and classy. The quality of the accessories is not good, but the appearance is absolutely luxurious.
It's okay to go to the door and window exhibition and you will know that the door and window hardware accessories and appearance of 200 yuan are quite beautiful, and they are packaged into a brand through operation and promotion, then sell 2,000 yuan per square meter.
There is no brand for doors and windows! The packaged brands are just for selling higher prices! Those so-called brands, they can do doors and windows to find a small door and window factory can also do, even small door and window shops can do.
If you want me to recommend, the current casement window window screen one PVB laminated glass LOW-E glass is quite good. It can also be used as drift window, inner opening and inner falling, and opening bottom-hinged are all good. It is better not to use hollow glass.
But then again, there are still several brands worth recommend:
1. Hennessy doors and windows: because Hennessy doors and windows were formerly made of hardware accessories, they have strict requirements on sealing, heat insulation and sound insulation in the quality of doors and windows.
2. Imported brands are more famous in Germany Schüco, Italy Aluk, Italy rockdy (Ronchetti), Japan YKK, Norway Hydro. The general mode of doors and windows of these brands is to export aluminum formula. In China, we can find a relatively large aluminum substitute for processing, and wholesale profiles to door and window processing plants with relatively strong strength that have passed their company certification all over the country, once authenticated. These door and window factories can buy their company's aluminum materials, (some of which require relatively high profile materials to be imported from abroad) and use their foreign company's technology and production technology to process doors and windows and create their brands. Generally speaking, as long as the doors and windows of these brands are not fake, the doors and windows of these brands are actually made formally. The doors and windows are all very good, the quality is also reliable, and the price is of course relatively high. Therefore, most of the doors and windows of foreign brands are processed in China. A small number of doors and windows with extremely high requirements will be processed abroad and then imported into the whole window. This kind of doors and windows are generally tens of thousands per square meter, which we generally do not use.
Domestic first-line brands are usually door and window factories that process for these foreign door and window brands. Generally, they are relatively powerful local manufacturers. After gradually becoming foreign brands, they have learned foreign door and window technologies, develop (imitate) door and window technology and create a brand. The aluminum alloy materials used may not be as good as the formula of foreign brands, but they also use relatively good aluminum alloy materials with strength and cavity structure design optimization (the cavity structure imitating foreign brands is slightly modified).
Relatively good domestic brands such as Harbin senying (the product quality is very good, which can be said to be our pride made in China and has been exported to northern Europe and other regions ten years ago), dalian Zhengdian doors and windows (I have visited the factory and the factory quality management is very good).
