The current broken bridge aluminum door and window market can be said to be complex, broken bridge aluminum door and window how much money a square? Different manufacturers give different prices for bridge broken aluminum doors and windows. Some manufacturers offer aluminum doors and windows with broken bridges as low as plastic steel. Can the price of plastic steel really make broken bridge aluminum doors and windows?
The answer is: absolutely impossible. The price of a ton of brand plastic steel door and window profiles is about 10000 yuan, and the price of a ton of brand broken bridge aluminum profiles is about 26000 yuan. Since the price and cost of the two materials are so different, why is the price of bridge broken aluminum doors and windows so low?
If you buy the broken bridge aluminum door and window quotation in 200-300 yuan per square meter, it is sure that this is fake and inferior bridge aluminum, among which the most serious adulteration is thermal insulation strip. The high-quality broken bridge aluminum doors and windows are equipped with PA66 nylon heat insulation strip, and the low-quality and low-cost broken bridge aluminum door and window is equipped with PVC heat insulation strip, which can be seen smooth and concave convex phenomenon with naked eyes.
Xiaobian visited Nanhai District, the base of Duanqiao aluminum doors and windows in Foshan. This is the most concentrated place for aluminum doors and windows of broken bridge in Guangdong Province. After visiting more than a dozen manufacturers of aluminum doors and windows of broken bridge, they found that the prices of aluminum doors and windows of broken bridge produced by these manufacturers are low, most of the insulation strips are PVC insulation strips, and the production workshop is still in mass production, which should be used on some construction sites, because For some developers, in order to get cheap, steal materials and make huge profits, they order inferior aluminum doors and windows of broken bridge here.
So what is the main difference between PA66 nylon strip and PVC heat insulation strip for bridge broken aluminum doors and windows?
At present, the heat insulation strips of broken bridge aluminum alloy doors and windows are nylon heat insulation strips and PVC heat insulation strips. If the quotation is calculated according to one square meter, the price of nylon heat insulation strip is more than ten yuan compared with PVC heat insulation strip. Because some consumers are not very familiar with the broken bridge aluminum doors and windows, resulting in the purchase of cheap, manufacturers and in order to make huge profits, usually use PVC insulation strip to replace nylon insulation strip. Nylon strip not only plays the role of heat insulation, heat preservation and noise isolation, but also is high temperature resistant and non combustible. The use of nylon heat insulation strip can avoid the gap between heat insulation strip and metal due to thermal expansion and cold contraction. On the contrary, PVC heat insulation strip will cause gap between heat insulation strip and finance due to thermal expansion and cold contraction, so as to achieve the effect of thermal insulation and thermal insulation. How many aluminum doors and windows are broken Money per square meter? Although the price of the broken bridge aluminum doors and windows is low, compared with the high-quality broken bridge aluminum doors and windows, the effect of sound insulation, heat insulation and heat preservation is far from satisfactory.
