Aluminum alloy is a kind of metal raw material widely used in various modern industries. Especially in the door and window industry in the modern construction industry, it is widely used. The high-quality aluminum alloy doors and windows not only have a gorgeous appearance, but also exquisite workmanship and long service life. The inferior aluminum alloy doors and windows not only have no texture, but also show the owner's life taste, and the service life will not be too long. How can I buy high-quality aluminum alloy doors and windows in the process of selecting aluminum alloy doors and windows? Today Xiaobian is here for your analysis!
Tips and methods for buying aluminum alloy doors and windows:
It is preferred to check the materials of the merchant products. The aluminum profiles used for high-quality aluminum alloy doors and windows, thickness, strength and oxide film should meet the relevant national standards. The wall thickness should be above 1.2 mm and the tensile strength should be less than mm per square meter. For 157 Newtons, the yield strength should be 108 Newtons per square millimeter and the oxide film thickness should be 10 microns. If the above standards are not met, it is inferior aluminum alloy doors and windows, which cannot be used.
Secondly, we must pay attention to the processing quality of the products, high-quality aluminum alloy doors and windows, fine processing, careful installation, good sealing performance, and freely switch. Inferior aluminum alloy doors and windows, blindly selected aluminum profiles and specifications, processing rough and shoddy, sawing instead of milling, not installed according to requirements, poor sealing performance, switch is not free, not only leaking wind and rain and glass burst phenomenon, but also encountered When it comes to strong winds and external forces, it is easy to scrape or knock down the push-pull parts or the glass, causing damage to people.
Finally, we must pay attention to the price of the product. Under normal circumstances, high-quality aluminum alloy doors and windows are about 30% higher than the inferior aluminum alloy doors and windows due to the high production cost. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have much lower tensile strength and yield strength than the relevant national standards. The use is very unsafe, but the price of such aluminum alloy doors and windows is naturally more expensive. The price of inferior aluminum alloy doors and windows is naturally much cheaper.
Whether it is to do the sun room, seal the balcony, decorate the house, doors and windows are essential, so Xiao Bian suggests that you choose a regular aluminum alloy door and window manufacturers, in order to make you feel at ease, use comfortable.
