Now many people buy windows and doors, will choose to buy broken bridge aluminum alloy windows, and the market is also full of some fake broken bridge aluminum doors and windows, "true and false" broken bridge aluminum doors and windows how should I distinguish? What are the purchasing skills of broken bridge aluminum doors and windows? Next, let's take a look at the structural diagram of the broken bridge aluminum alloy window and the related selection skills of the broken bridge aluminum window, hoping to help you in the selection of the broken bridge aluminum window.
1、 Structural drawing of bridge broken aluminum alloy window
Section is also one of the standards to distinguish the quality of broken bridge aluminum alloy window. The geometric angle of the normal bridge broken aluminum section is very standard and beautiful, and the profile will not deform after cutting, so the stability is very good. For example, p70 type of broken bridge aluminum window, the thickness is 7 cm, and the strip is less occupied, so it is firm. But the fake bridge aluminum, will use a lot of threading to support, the weight is insufficient, the stability is poor.
The principle of the broken bridge aluminum alloy window is to use PA66 nylon to separate and connect the two layers of aluminum alloy Indoor and outdoor into a whole, forming a new type of thermal insulation aluminum profile. According to the connection mode, it can be divided into strip type and glue injection type. Using this kind of profile as door and window has superior heat insulation, and completely solves the fatal problem of aluminum alloy conduction and heat dissipation fast and does not meet the requirements of energy conservation The old and difficult problem of "aluminum alloy sliding window is not tightly sealed" is completely solved by adopting some new structure matching forms. The specific structural diagram of bridge broken aluminum alloy window is as follows:
2、 Purchasing skills of broken bridge aluminum doors and windows
At present, only white and champagne colors are produced by the original factory of "fengaluminum", and the other colors are sprayed by the processor himself.
Due to the large amount of impurities in the aluminum materials, the extruded bridge broken aluminum alloy window profiles generally have many marks.
No. 3. There will be brand spray code on the aluminum alloy window profile of "Fenglv" bridge break. The false spray code is easy to be erased, while the genuine one is difficult to remove even with some hard things.
The insulation strip in the middle of № 4 and "fengal" bridge breaking aluminum alloy window profile is nylon, while many counterfeit products are made of PVC. The difference between the two is that nylon material looks rough, while PVC is smooth and shiny.
The thickness of genuine window profile is about 1.4mm, and the thickness of door profile is about 1.6mm.
Due to the backward spraying technology, the surface of counterfeit products is generally rough, while the surface of genuine products is glossy without ripple.
It is very helpful to know the structural drawing of the bridge broken aluminum alloy window and the purchasing skills of the broken bridge aluminum window. When we buy the broken bridge aluminum alloy window, we'd better choose the famous brand flagship store to buy the broken bridge aluminum window, which has more guarantee in the after-sales and product quality.
