The quality of Yidun aluminum alloy safety doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), the quality of aluminum surface treatment and internal processing, and the price of aluminum alloy doors and windows

the quality of Yidun aluminum alloy safety doors and windows also depends on the quality

look at the materials. The thickness, strength and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows should comply with relevant national standards. The wall thickness should be more than 1.2mm, the tensile strength should reach 157 Newtons per square millimeter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns

high quality aluminum alloy doors and windows, with fine processing, exquisite installation, good sealing performance and easy switching. Poor quality aluminum alloy doors and windows, blindly select aluminum profile series and specifications, process rough, use sawing instead of milling, do not install as required, poor sealing performance, uneasy switching, not only air and rain leakage and glass cracking, but also encounter strong winds and external forces, it is easy to scrape or bump the push-pull part or glass, and damage objects and hurt people

in general, due to the high production cost, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of low-quality aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have tensile strength and yield strength much lower than the relevant national standards, which is very unsafe to use. In addition, at present, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce costs, Jerry built products, shoddy products, the hidden dangers of larger products, generally should not be used. It is best to choose the products of regular aluminum alloy door and window manufacturers
