the price of doors and windows is really too messy. To what extent is it messy? For 55 broken bridge doors, the cheap ones are only about 300 to 400 per square meter, while the expensive ones are 700 to 800 per square meter, and even there are more than 1,000 per square meter, what is the difference between them? On the surface, there is no difference between them, so what is the problem? Today's editor makes a comparison between materials and crafts.
I. Materials
1. Profiles
a. 55 broken bridge profiles are now in the market? Shrimp? . 2mm to 1.8mm are available, only a 6 m long profile only due to different thickness, the difference is as much as 60.70 yuan.
B. Division of large factories and small factories: due to equipment and technology, the processing cost of profiles produced by small workshops is between 2,000 and 3,000 per ton, however, the processing fee of a large factory reaches 5,000 to 6,000 yuan, which is also a big difference!
2. Hollow glass
a, 55 broken bridge hollow glass has non-tempered hollow, single-sided tempered hollow, double-sided tempered hollow, non-tempered hollow about 70 yuan per square meter, while double-sided tempered hollow is more than 100 yuan per square meter.
B. 55 there are three types of hollow glass that can be assembled with broken bridge glass, namely 5 6a, 5 9a, 5 12a 5. Among these three types, 5 6a 5 has the worst sound insulation performance, 5 12a 5 has the best sound insulation performance, and their price difference is between 25 and 30 yuan per square meter.
3. Heat insulation strip
ordinary PVC insulation strips are usually about 6000 to 7000 tons, while nylon 66 insulation strips are up to 28000 yuan per ton. You can calculate the difference between them!
4. Hardware accessories
in terms of a set of hardware accessories, low price market? Are you afraid of being bad? 00 yuan, and a set of good quality reaches 200 or 300 yuan, especially? The brand is as high as 4,500 yuan. This difference is four or five times.
5. Silicon sealant
in? 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?? Is it better structural adhesive for quality?
II. Craft
the whole set of production equipment for small workshops costs 7 to 80000 yuan. However, only double-head saw of each high-precision factory reaches 6 to 70000 yuan. This kind of investment is not because the factory is rich, but because their cutting accuracy is indeed not in 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 the quality of the products produced? High precision? To produce good products that meet the quality standards, the hardware investment must first meet the standards. Only when the hardware meets the standards can the products that meet the standards be produced. The cost is undoubtedly higher.
