Now broken bridge aluminum doors and windows it is more and more popular with people, and it is more and more common to use broken bridge aluminum profiles, because its section is in the form of broken bridges, which can effectively organize the conduction of hot and cold energy, thermal insulation, sound insulation and sealing are better than other profiles, but with the widespread use of broken bridge aluminum, the market broken Bridge aluminum profile there are more and more brands. In addition to several major brands known to everyone, there are also independent brands of various door and window manufacturers. How should we distinguish whether the broken bridge aluminum is good or bad?
I. Look at the surface quality of profiles
the quality of the profile can be observed from the surface of the Broken Bridge aluminum profile. The good Broken Bridge aluminum surface is shiny and textured, and the surface is sprayed with natural color treatment. It feels smooth without any trace, however, the surface of the Broken Bridge aluminum with poor quality is rough, uneven color, no luster, and looks unnatural. After a period of time, the worse broken bridge aluminum will change color or fade, and the color is not full.
Second, look at the profile section structure
good broken bridge aluminum doors and windows the geometric angle of the section is accurate, the profile will not be slightly bent, and the angle is correct. It depends on whether the profile wall thickness and thickness meet the standard (1.4mm,1.6mm,1.8mm), poor quality doors and windows, it will adopt the form of threading to meet the profile model. The material of aluminum is less. Of course, the use effect is not so good, and even the service life is reduced.
3. Look at the configuration of profiles (insulation strip, sealing strip)
broken Bridge aluminum, we all know that the heat insulation strip is used to divide the profile into two interfaces inside and outside, so as to achieve the remarkable effect of cold insulation. The heat insulation strip in the middle plays a particularly important role, so the heat insulation strip is very important, good broken bridge aluminum doors and windows use pa66 nylon strips, while inferior Broken Bridge aluminum doors and windows use pvc insulation strips. pa66 surface is a matte texture color blackened, while pvc looks smooth and white.
