for many owners, the choice of high-quality aluminum alloy doors and windows is a major problem in decoration. Facing the vast information age, how to choose high-quality and cost-effective aluminum alloy doors and windows? In order to answer the doubts of the majority of owners, the following will show you three key elements of choosing aluminum alloy...

key element 1: strictly inspect the sealing performance of doors and windows

according to aluminum alloy door experts, owners must pay attention to its sealing performance when choosing aluminum alloy doors with inlaid glass, especially when choosing aluminum alloy doors and windows with hollow glass design. Because if the sealing of doors and windows is not good, it will lead to dirt in the hollow layer of aluminum alloy doors and windows, which will seriously affect the appearance. Not only that, ordinary wool tops will curl when exposed to water and lose their sealing effect. In winter, water absorption will also freeze, seriously affecting the smoothness of door opening and closing

excellent aluminum alloy brands will use silicified tops to make them more sealing. And with advanced hot pressing sealing technology for all-round sealing treatment, it can not only effectively prevent dust and water, but also play a very good sound insulation effect

key element 2: processing quality of aluminum alloy doors and windows

high quality aluminum alloy doors have fine processing and exquisite welding, especially some spliced parts are very hard and flat. The inferior aluminum alloy doors and windows are blindly selected with aluminum profile series and specifications, and the processing is rough. The positions such as door frame corners cannot be spliced smoothly, and sometimes there are even large gaps. When shopping, consumers should pay special attention to check whether there are welding defects, such as open welding, missing welding and so on

key element 3: whether the material of aluminum alloy doors and windows is bridge cutoff heat insulation aluminum profile, and the wall thickness of the main profile should be greater than 1.4mm; The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to buy; Check the surface of aluminum alloy profile, and there should be no depression or bulge; Aluminum alloy doors and windows should avoid purchasing profiles with open bubbles (white spots) and ash (black spots) on the surface, as well as obvious defects such as cracks, burrs, peeling, etc; The thickness of the oxide film should reach 10 microns. When purchasing, you can gently scratch the surface of the profile to see whether the oxide film on its surface can be wiped off

Yidun doors and windows pay special attention to quality. The strengthening of material thickness has significantly improved the load-bearing, deformation prevention and durability of this product
