In the market of Shanghai doors and windows, the design, manufacture and installation technology of bridge broken aluminum doors and windows are very mature. Generally, the price is 500 yuan per square meter. Xiaobian found that recently some friends only spent 300 yuan per square meter to buy the so-called broken bridge aluminum doors and windows, which must be of poor quality. Generally, the unit price of broken bridge aluminum doors and windows in Shanghai is more than 300 yuan per square meter. As for what is more than 300 yuan per square meter, it is absolutely impossible to make broken bridge aluminum doors and windows. It is OK to make plastic steel doors and windows. The aluminum cost of bridge breaking is there, so the aluminum doors and windows of broken bridges are put there If the window price is too cheap, don't believe it. There are many traps.
Shanghai broken bridge aluminum door and window price several hundred one square meter is not reliable!
Broken bridge aluminum doors and windows have entered the Shanghai market for many years, and the price has been very transparent, so there is no such a big gap. The total price of general brand broken bridge aluminum doors and windows plus hardware is 700-950 yuan per square meter. This is the configuration of imported hardware. If domestic hardware is used and the number of windows is small, the average price is 600-750 yuan per square meter It is impossible for the broken bridge aluminum to be true at the price of two or three hundred yuan per square meter. There is only one possibility of this kind of quoted broken bridge aluminum doors and windows, which is a price trap.
Because there are more than two or three hundred square meters of broken bridge aluminum doors and windows in Shanghai, even fake prices, such prices can not even buy broken bridge aluminum profiles, that is, the price of a plastic steel doors and windows, some businesses quote low prices, using inferior materials for processing, such as aluminum profiles made of recycled aluminum, or using profiles whose material thickness is far lower than the national standard. Poor quality bridge broken aluminum door and window profiles may use plastic instead of nylon in the middle of the broken bridge, which has serious consequences. First, it is not solid, second, it is easy to aging; third, it has a large deformation rate of thermal expansion and cold contraction, which reduces the thermal insulation coefficient. After a long time, the whole window is in danger of falling apart.
Remind everyone to choose reliable door and window manufacturers in decoration, so as to have safety protection.
