The five lies in the door and window industry, see if you have been deceived?
The first lie is that many doors and windows like to name themselves German doors and windows to pretend to be foreign brands, but the real situation is that there are neither German shares nor German technology, there may only be a certain hardware is a German brand, the real German broken bridge aluminum doors and windows ** in 3000-4000 yuan, don't be deceived.
Second, the top ten brand rankings, there is no authoritative unit in China to conduct door and window brand evaluation and ranking, what you search online is the door and window business money to play advertising, you search ten times may not be the same.
Third, imported hardware, most businesses will say that their hardware is imported, in fact, many well-known imported hardware brands have been localized, such as the United States Himec, Denmark Stanford, Germany Renas, etc., and there will also be some merchants with domestic counterfeit imports, so merchants tell you that imported hardware you have to ask whether it is domestically produced.
Fourth, the seamless welding process of the window frame is not that the seamless welding is not good, but that many manufacturers only work the surface of the window frame in order to follow the trend but do not have real technology, and the internal structure is actually still spliced with corner codes.
Fifth, the more cavities, the better, in order to enhance the value of doors and windows, many businesses like to start with the cavity, the cavity to 6 cavities, 7 cavities, but the number of cavities is not the main factor that determines the performance of doors and windows, but also through the sealing, glass thickness, aluminum quality structure, installation process and other joint effects, too many cavities may also affect the sealing and weight of the window frame.
