First observe its surface; The quality is relatively good Broken Bridge aluminum doors and windows the surface is smooth and textured, and the color of the surface is also very uniform and smooth. However, the thickness of high-quality broken bridge doors and windows on the materials conforms to the national regulations, and its thickness can be measured at the time of purchase, generally not less than 1.2mm. Secondly, try the doors and windows when purchasing; See whether the workmanship is fine and whether the switch is flexible. Finally, you can also choose by cutting surface; The angle of high-quality Broken Bridge aluminum doors and windows on the cutting surface will be very accurate.
Broken Bridge aluminum doors and windows the selection method is as follows:
1. The quality selection of the product surface can be judged by observing the broken bridge aluminum doors and windows surface. Generally speaking, the quality is relatively good Broken Bridge aluminum doors and windows the surface is smooth and textured, and the color of the surface is even and smooth. However, the surface of doors and windows with poor quality is rough and the color is uneven, which makes people feel very uncomfortable.
2. Looking at its materials, the thickness of high-quality broken bridge doors and windows conforms to the national regulations. Its thickness should generally not be less than 1.2mm, its anti-strong pull should be more than 157 newton per square mm, and its oxide film thickness should be more than 10 μm. If the selected broken bridge aluminum doors and windows does not reach these, do not buy it.
3. Depending on the processing, check whether the workmanship is fine, whether the switch is flexible, and whether the sealing performance is good or not. Generally, inferior doors and windows are made of aluminum profiles. It is not only rough in workmanship, but also inflexible in switch, which often causes air leakage and rain leakage. While the quality is broken bridge aluminum doors and windows, the quality of its processing is needless to say. Finely processed. Good sealing performance and easy switch. Therefore, when purchasing, we should choose broken bridge aluminum doors and windows with reliable processing quality.
4. Look at the cutting surface, the quality is broken bridge aluminum doors and windows, the angle on the cutting surface is accurate, and the phenomenon of bending and twisting will not occur. However, the section of broken bridge aluminum doors and windows with poor quality is not so regular.
5. Depending on the price, generally, the production cost of broken bridge aluminum doors and windows with good quality is relatively high, and the price is much higher than that of broken bridge aluminum doors and windows with inferior quality. Therefore, we recommend that you purchase broken bridge aluminum doors and windows sold by regular manufacturers.
Method 2:
How should I choose broken bridge aluminum doors and windows?
To be honest, the price of broken bridge aluminum doors and windows is uneven on the market now, ranging from 300 yuan per square meter to 1500 yuan per square meter. Many consumers can't tell which is better or worse. When they come up, they ask the price, get it if it's cheap. This is actually wrong. For users, it is very necessary to purchase high-quality doors and windows. Choosing broken bridge aluminum doors and windows is not only about the price, but also the expensive broken bridge aluminum doors and windows is definitely suitable, the cheap broken bridge aluminum doors and windows is not necessarily really broken bridge aluminum.
Today, I would like to share with you how to choose broken bridge aluminum doors and windows:
See series:
Broken Bridge aluminum doors and windows has different series, like: Broken Bridge aluminum 60/70/80/90/108 series. The difference between these figures lies in the width of the profile section. 60 series represents a material width of 6cm, similarly: 70 series is 7cm, 80 series is 8cm......
The larger the number of series, the better the thermal insulation effect of broken bridge aluminum doors and windows? NO! This is a misunderstanding. If the merchant tells you that the 70 series is better than the 60 series thermal insulation, it must be that he is cheating you. The larger the number of bridge-cutoff aluminum alloy doors and windows series, the wider the corresponding window frame and the higher the price, but the better the thermal insulation performance is not necessarily.
Look at the heat insulation strip:
There are many aspects that affect the thermal insulation performance of broken bridge aluminum doors and windows. It is important to look at the thermal insulation strip.
1. Look at the material of heat insulation strip, is it cheap PVC or high quality nylon 66 heat insulation strip? The material of heat insulation strip is the basic guarantee of broken bridge aluminum doors and windows quality. Nowadays, many unscrupulous merchants use inferior PVC heat insulation strip to fill up the quantity in order to reduce costs, and the heat insulation effect is very small.
2. Look at the size of the insulation Strip. The larger the size of the empty insulation strip, the higher its insulation performance.
3. Look at the shape of the heat insulation strip, which is also called I-type heat insulation strip. Its heat insulation performance is not as good as that of C font heat insulation strip. I-shaped groove is easy to accumulate water, soaked with adhesive strips, and the adhesive strips are easy to age. C font is more expensive, but the cavity-type heat insulation strip has the best heat preservation performance.
Look at the wall thickness:
The wall thickness of broken bridge aluminum doors and windows is within the range of 1.4 mm-2.0mm, and the international standard thickness is 1.4mm. However, the broken bridge aluminum doors and windows of many bad merchants is aluminum alloy made of recycled aluminum, and the wall thickness is only 1.0 mm-1. Between 2mm, the strength of this aluminum alloy is not enough at all. For senior users, it will face potential safety hazards, which cannot withstand strong winds and is easy to deform. Therefore, when purchasing, you should show the merchant that the wall thickness is less than 1.4mm.
Look at the glass:
If you want good heat insulation and sound insulation, choose hollow glass. There are several specifications of broken bridge glass hollow glass, generally 5 9A 5,5 12A 5,5 20A 5,5 27A 5. Among them, the sound insulation performance of 5 9A 5 is the worst, and the sound insulation performance of 5 27A 5 is the best, and their general price difference is 30-40 yuan. Beware of the merchant's cute act, for example, it was originally 5+12+5 glass, but 4.3 glass was used instead of 5 glass, guangguang can make merchants earn 50 yuan per square meter. Tempered glass should be sure whether there is a 3C certification mark. If the sealant looks like a dog gnawing, Pass it quickly.
Look at the hardware:
A set of doors and windows are calculated to use a lot of hardware. Doors and windows often need to be opened and closed. If cheap hardware is used, it is estimated that it will break down in less than two or three years. Therefore, when purchasing broken bridge aluminum doors and windows, hardware must not be saved, and brand hardware should be selected. You can ask the merchant when purchasing, "What brand is your hardware?" If the merchant's reply is original hardware or original hardware, it must be hardware produced by a small workshop, and the quality will not be good. If the merchant answers big-name or imported hardware, it sounds good, but be sure to ask whether all the hardware or just the handle is worth it according to the quotation given by the merchant.
All right, let's talk about the selection of broken bridge aluminum doors and windows. My personal suggestion is that the requirements for sound insulation are not high, so it is enough to choose ordinary insulating glass (5 12A 5) and 60 series. If you have high requirements for sound insulation, the community is noisy, or the home is equipped with large floor windows and the floor is relatively high, you can choose 70 series, the price is generally 800-1200 yuan/㎡, for reference only.
