In broken bridge aluminum doors and windows what should be paid attention to when choosing the above, we should comprehensively consider the wall thickness of profiles, hardware, air tightness of materials, water tightness, sound insulation and thermal insulation performance and glass. Next, let's take a look at it specifically.
I. Look at the wall thickness of the profile
the thickness of the profile wall should be greater than or equal to 1.4mm. If it is lower than this value, it is the profile produced by small manufacturers, and there are potential safety hazards in terms of quality. Consumers can go to the manufacturer to inspect and measure the wall thickness of the profile with calipers when necessary.
II. Hardware
hardware, which is the hinge when it is opened Broken Bridge aluminum doors and windows, imported hardware such as grid House, Noto, and Scarlett are trustworthy. However, domestic hardware, such as Zhongwang, Jianlang and DBS, are of good quality.
3. Air tightness, water tightness, sound insulation and thermal insulation
air tightness, watertightness, sound insulation and thermal insulation are more troublesome. It needs to be tested by professional departments, but regular manufacturers are within the required numerical range, which can be assured. However, it is not necessarily a small workshop on the roadside. This consumer has to polish his eyes.
IV, hollow glass
there are several models of hollow glass now, including 5 9A 5, 5 15A 5, 5 22A 5 and other models, depending on which series of broken bridge aluminum are used by consumers.
There are only a few points that should be paid attention to when choosing broken bridge aluminum doors and windows. In the final analysis, consumers must remember that no matter what brand or model of broken bridge aluminum is made, they must order from regular manufacturers, it not only saves the middle ring of the building materials market, but also guarantees it.
