First, materials. The thickness, strength and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows shall comply with the relevant national standards. The wall thickness shall be more than 1.2 mm, the tensile strength shall be 157 n / m2, the yield strength shall be 108 n / m2, and the oxide film thickness shall be 10 μ M. The above, if not up to the standard aluminum doors and windows.
Second, processing. High quality aluminum alloy doors and windows, fine processing, good sealing performance. Poor quality aluminum alloy doors and windows, blind selection of aluminum profile series and specifications, rough processing, saw cutting instead of milling processing, not according to the requirements of installation, poor sealing performance, switch is not free, not only air and rain leakage and glass burst phenomenon, but also encounter strong wind and external force, it is easy to pull parts or glass scraping or falling, damage and injury.
Third, price. In general, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of inferior aluminum alloy doors and windows due to its high production cost. Some aluminum alloy doors and windows with wall thickness of only 0.6-0.8 mm aluminum profiles have tensile strength and yield strength much lower than the relevant national standards, so they are not safe to use.
