Insulated bridge cutoff Aluminium alloy door The outstanding advantages of the window are high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life, good decoration effect, and the use of * * * bridge cutoff aluminum alloy door window , is the preferred product of * * * building windows.
Windows bring us light, and in the cold and windy winter, windows also shield us from the cold. Their sealing performance has become an important index for people to choose windows. In the past, when people chose windows, they might pay more attention to their opening performance. In fact, they understand their thermal insulation performance, window materials Glass , hardware and so on are essential. The thermal insulation bridge cutoff aluminum alloy window is an improved type launched on the basis of the old aluminum alloy window to improve the thermal insulation performance of doors and windows. The aluminum alloy profile is divided into internal and external parts to block the heat conduction of aluminum by strengthening the nylon spacer strip. The material and quality of reinforced nylon spacers directly affect the durability of insulated bridge cutoff aluminum alloy windows. This is the reason why more and more people choose the bridge cutoff aluminum doors and windows.
1. Materials: the thickness, strength and oxide film of the aluminum profiles used for high-quality bridge cutoff aluminum alloy doors and windows should comply with the relevant national standards. The wall thickness should be more than 1.4 mm, the tensile strength should reach 157 N/mm2, the yield strength should reach 108 N/mm2, and the oxide film thickness should reach 10 microns. If the above standards are not met, it is inferior aluminum alloy doors and windows, which cannot be used.
2. Look at the processing: high-quality bridge cutoff aluminum alloy doors and windows, with fine processing, exquisite installation, good sealing performance, and free opening and closing. Poor quality bridge cutoff aluminum alloy doors and windows are blindly selected from the aluminum profile series and specifications. The processing is rough and does not meet the requirements. Saw cutting is used instead of milling, and the installation is not carried out according to the requirements. The sealing performance of the product is poor, and the switch is not free. The drawbacks of poor quality products begin to be exposed. Not only are there air and rain leaks and glass cracks, but also the push-pull parts or glass are easy to be blown off or knocked off by strong winds and external forces, which can damage people. Therefore, when we buy doors and windows, we must buy reliable brands. We should not try to be cheap for a while to avoid unnecessary trouble in the future.
3. Price: In general, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of low-quality aluminum alloy doors and windows due to high production costs. Some bridge cutoff aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 1.2-1.3 mm have tensile strength and yield strength much lower than the relevant national standards, which is very unsafe to use. So when buying, never try to be cheap.
Mercer Aluminum Doors and Windows Co., Ltd. reminds you that choosing a regular bridge cutoff aluminum manufacturer is the guarantee of your happy life.
