How much is the aluminum doors and windows of a square bridge?
The price of a ton of brand plastic steel door and window profiles is about 1000 yuan, and the price of a ton of brand broken bridge aluminum profiles is about 26,000 yuan. Because the prices and costs of these two materials are so different.
If the price of the broken-bridge aluminum doors and windows you buy is above 200-300 yuan per square meter, you can be sure that it is fake and shoddy broken-bridge aluminum, among which the heat insulation strip is the most adulterated. High-quality broken-bridge aluminum doors and windows are equipped with PA66 nylon insulation strips, and inferior broken-bridge aluminum doors and windows are equipped with PVC insulation strips. This kind of inferior insulation strip can be seen smooth and concave with the naked eye.
