Broken bridge aluminum doors and windows are the preferred materials for sealing balconies in the market now. Many owners find that the price difference of broken bridge aluminum doors and windows is relatively large in the process of purchasing. From the quoted price of 300 yuan per square meter to 800 yuan per square meter, there are even broken bridge aluminum doors and windows with a quotation of more than 1000 yuan. What are the conditions that affect the price of broken bridge aluminum doors and windows? Let's analyze them together.
The thickness, strength, oxide film and service life of aluminum profiles used for high-quality bridge broken aluminum alloy doors and windows should conform to the relevant national quality inspection standards. The profile wall thickness should be more than 1.4 mm to be considered as high-grade bridge broken aluminum alloy doors and windows products. The tensile strength should reach 157 Newton per square millimeter, the bending strength should reach 108 newton per square millimeter, and the oxide film The thickness should be up to 10 microns. If it fails to meet the above specifications, it is a defective bridge broken aluminum alloy door and window, which cannot be used.
The use of high-quality aluminum bridge doors and windows is more expensive than the general use of glass doors and windows.
Accessories are hardware lock accessories. Advanced bridge breaking aluminum alloy door and window products use imported hardware accessories, while relatively low-level bridge breaking aluminum alloy door and window manufacturers use hardware of some small domestic manufacturers. Generally, the price of imported hardware is more expensive than that of domestic hardware. Now the best hardware used in the market is imported hardware accessories from Germany.
High quality bridge broken aluminum alloy doors and windows, precision processing, elegant device, good sealing function, switch self. For defective bridge broken aluminum alloy doors and windows, the aluminum profile series and standards are blindly selected, and the processing is done in a shoddy way. Instead of milling, sawing is used instead of milling. If the device is not installed according to the requirements, it not only leaks air and rain and presents glass burst phenomenon, but also encounters strong wind and external force, and the push-pull part or glass glass will simply blow off or collide, causing damage to people.
