What should we pay attention to when buying aluminum alloy doors and windows? Xiaobian believes that many people will encounter such difficulties, do not know how to identify the quality of aluminum alloy doors and windows. In order to help you to solve this problem, I brought you about the aluminum alloy door and window purchase skills, I hope to help you to select high-quality aluminum alloy doors and windows products.
1、 Look at the surface texture
When we buy aluminum alloy doors and windows, we can use the naked eye to detect to see whether there are some obvious scratches on the surface of aluminum alloy doors and windows, especially pay attention to the corner, whether there are bruises and so on. In addition, look at the surface gloss of aluminum alloy doors and windows, to see whether the surface of the door has serious paint off paint, bulging. Finally, we should pay attention to the name of the manufacturer, date of production, QS logo and so on. We have bought three products without doors and windows, but there is no quality guarantee.
2、 Feel the texture
When we are looking at the aluminum alloy doors and windows, we can also touch them with our hands at the same time to see how the texture of the aluminum alloy doors and windows is. Some concave and convex defects that may not be seen may be detected by hand. Aowei doors and windows tell you that good quality aluminum alloy doors and windows feel smooth and delicate.
In addition, manually pull the handle and other hardware to see if there is a loose situation, or the use is not smooth. If you can't buy more hardware, you don't have to spend too much time on the cheap ones. You don't have to spend too much time on the cheap ones.
3、 Look at the thickness of the profile
The thickness standard of aluminum alloy doors and windows, such as aluminum alloy and broken bridge aluminum, is 1.4mm, and the quality is not up to standard if the profiles of 1 mm and below are used; many manufacturers of bridge broken aluminum doors and windows may use 1.2mm thick profiles for processing, which is generally not the normal bridge breaking aluminum.
If the thickness of profile is not enough, the strength is not enough, that is to say, it is easy to deform and has short service life.
4、 Selection of glass materials
It is suggested to choose double-layer tempered glass, which is safer, stronger and not easy to break.
5、 Look at the installation
Installation is also very important for aluminum alloy doors and windows. If the installation is not in place, it is easy to have deformation or hidden danger in the later stage. We must remember to leave some expansion joints in the window frame, because they have thermal expansion coefficient. Only by leaving enough expansion joints can the deformation of doors and windows be ensured. In order to ensure the performance of waterproof and sound insulation, the expansion joint should be filled with elastic material.
6、 Look at the service
At the time of purchase, we should ask the manufacturers of aluminum alloy doors and windows about the maintenance and warranty of later period, so as to avoid unnecessary trouble in the future.
