Bridge-cutoff aluminum alloy doors and windows there are many specifications. Mainstream profiles generally have 55 types, 60 types, 65 types, 70 types, 75 types, and 80 types. The mainstream profiles integrated with window screen generally have 80 type, 95 type, 100 type, 108 type, 125 type, 130 type and 150 type. Broken bridge aluminum doors and windows the market price is really messy. To what extent? Take the 55 broken bridge door as an example. The cheap one is only about 300 to 400 square meters, while the expensive one is 700 to 800 square meters, and there are even more than 1000 to 2000 square meters, what is the difference between these?
There is no difference between them from the outside, so where is the problem? Today, I will make a comparison between materials and techniques.
Material
1 profile
a. 55 the thickness of broken bridge profiles is now available in the market from 1.2mm to 1.8mm. Only one 6-meter-long profile has a price difference of 60.70 yuan only due to different thickness.
B. Big factories and small factories: due to equipment and technological reasons, the processing cost of profiles produced by small workshops is between 3,000 and 5,000 per ton, however, the processing fee per ton of large factories reaches 8,000 to 10,000 yuan, which is also a big difference!

generally speaking, good quality doors and windows are very elegant in choosing materials. There are mainly two kinds of aluminum materials circulating in the market, one is recycled aluminum, the cut and surface are rough, dull and the material is relatively "crisp"; The other is made of raw aluminum ingot, toughness, gloss, adhesion, the bearing capacity is relatively good, and the incision is flat, the density is high, and the hardness is strong.
2 hollow glass
glass mainly includes single-layer ordinary glass, single-layer toughened glass, hollow ordinary glass and hollow toughened glass. Each type has its own characteristics, such as hollow ordinary glass. The thickness of barrier on the market is generally 6mm, 9mm and 12mm. The glass is generally 4mm and 5mm. However, the impact resistance and bending strength of tempered glass are 3~5 times that of ordinary glass. Even if it is broken, the fragments will become honeycomb-like obtuse angle particles, which basically will not cause harm to human body.

when we choose glass of different materials according to our own situation, we should also observe the quality of the glass itself. Good quality glass, looking at it from the side, can't see spots, can't see ripples, good gloss, good transmittance.
3 Heat insulation strip
ordinary PVC insulation strips are generally about 6000 to 7000 tons, while nylon 66 insulation strips are as high as 28000 yuan per ton. You can calculate the difference between them!

4 Hardware
take a set of hardware for example, the low price is less than 100 yuan in the market, while a set of good quality is 200 or 300 yuan, especially for imported brands, it is as high as 400 or 500 yuan. This difference is four or five times.
In order to save production costs, many manufacturers will use inferior hardware accessories. But many people only care about the appearance and think it looks good. In fact, hardware accessories are related to the switch feel, flexibility, safety and service life of doors and windows. When purchasing, you must ask more questions and try more. The door lock broke down after less than a year. It should have been met by more than one person. Don't blame me for not reminding in advance. Some company locks are still equipped with that door, if the lock is broken, it may be difficult to find a matching change.

5 silicon sealant
in the installation broken bridge aluminum doors and windows in order to save money, some people use sealant for caulking for two or three yuan each, while others use structural adhesive on the outer wall to meet the quality requirements, each piece reaches more than 18 yuan. Take consumers as an example, do you want to use two or three pieces of glue to save money? Or use better quality structural adhesive for quality? You should also observe more when buying!
Craft
A complete set of production equipment in a small workshop costs 7 to 80000 yuan. However, only one high-precision double-head saw of a large factory reaches 6 to 70000 yuan. This kind of investment is not because the large factory has money, but because their cutting accuracy is indeed not at the same level! This is only to compare one device, and there are several other devices! Therefore, the investment of large factories is large, while that of small workshops is small! Who do you think is of good quality to produce products? High precision? To produce good products that meet the quality standards, hardware investment must first meet the standards. Only when hardware meets the standards can products that meet the standards be produced, and the cost is undoubtedly higher.

therefore, when choosing doors and windows, try to choose big well-known doors and windows brands. The workmanship is good in all aspects, and the quality must be guaranteed!
There are still many factors that affect the cost of doors and windows, so we are not here?? Aluminum? /p>
There is an old saying that it is called hundreds of customers in department stores. In fact, buying doors and windows products is much better than the current car market: 20 thousands or 30 thousands you can also buy a QQ car, but it has fewer functions, the space is smaller, the service life is shorter, and the running speed is slower; However, for hundreds of thousands or even millions of people to buy a Mercedes-Benz BMW, it only has more functions and stronger power, the safety factor is higher, and the interior is more luxurious. Whether you buy QQ or BMW depends on your family conditions and practical use.
Therefore, buying doors and windows products also depends on your own family conditions. If you are willing to solve the problem at one time, you can buy products with better quality. The price is higher, but the problem is solved at one time, no worries.
