(good doors and windows, choose new Dihao) nowadays, the door and window market is mixed. If you want not to be trapped, it is necessary to understand a little common sense of current aluminum alloy doors and windows. Next, I will teach you how to distinguish the advantages and disadvantages of aluminum alloy doors and windows

first, look at the surface quality of the profile

the quality of the profile can be observed from the surface of the bridge cutoff aluminum alloy profile. The surface of the good bridge cutoff aluminum alloy profile is glossy and textured, and the surface spraying color treatment is also very natural, which makes it feel smooth; The secondary broken bridge aluminum alloy doors and windows have rough surface, no gloss, and look unnatural. After a period of time, the poor broken bridge aluminum alloy doors and windows will change color or fade, and the color is not full

second, look at the profile section structure

good bridge broken aluminum alloy door and window profile section geometric angle is accurate, the profile will not be bent, twisted, and the angle is correct. Moreover, the thickness of the section is sufficient, such as the customized 60 model broken bridge aluminum alloy doors and windows. 60 means that the thickness of the profile is 6 cm, and this 6 cm is full broken bridge aluminum, and the proportion of threading is small; However, for the secondary bridge broken aluminum doors and windows, the 60 profile with virtual support will be used, and the threading strip will be used to support this thickness, so the aluminum material is less

III. look at the thermal insulation strips of profiles

thermal insulation strips are divided into imported and domestic. Most of the domestic thermal insulation strips are made of plastic PVC, and the imported thermal insulation strips are polyamide, that is, nylon thermal insulation strips. High quality bridge cutoff aluminum alloy doors and windows adopt imported heat insulation strips, which have better high temperature resistance and low temperature resistance, low heat conduction value, and can better achieve the effects of heat insulation, heat preservation, environmental protection and energy conservation, and can save energy by 20% - 30%
