Hello, the big difference is mainly due to the following reasons

(1) Main profiles used

1. Broken bridge profiles of the same model and specification (such as household aluminum alloy The 60 series and 70 series commonly used in doors and windows are now available in the market with thicknesses ranging from 1.2mm to 2.0mm. The price difference for a 6-meter-long profile is as much as 60 or 70 yuan just because of the different wall thickness of the material.

2. Differences between large and small factories: Due to equipment and process reasons, the processing fee per ton of profiles produced by small workshops is between more than 2,000 and 3,000 per ton, while the processing fee per ton of large factories is Reaching 5,000 to 6,000 yuan, this is not a small difference!

3. Insulating glass: The insulating glass used in broken bridge aluminum doors and windows includes: non-tempered glass insulated glass, single-sided tempered insulating glass, double-sided tempered insulating glass, non-tempered insulating glass per square meter Meter is about 70 yuan, while double-sided tempered hollow is more than 100 yuan per square meter.

The specifications of insulating glass also vary. For example, the 70 series commonly used in household broken bridge aluminum doors and windows can be equipped with 5 12A 5, 5 15A 5, 5 18A 5, 5 22A 5. These four Among the specifications, 5 12A 5 has the worst thermal and sound insulation performance, and 5 222 5 has the best thermal and sound insulation performance, and their prices will vary between 25 and 30 yuan per square meter.

The other is the production process of insulating glass. The glass processes produced by small glass factories and large glass factories are different. The finished glass products of large glass factories are produced with high quality and high standards, and the glass precision is high. , good gloss and good sealing environment.

4. Insulation strips of broken bridge aluminum: Ordinary PVC insulation strips are generally around 6,000 to 7,000 per ton, while nylon 66 insulation strips are as high as 28,000 yuan per ton. You can calculate What is the price difference between them?

5. Hardware: Take a set of internal-opening hardware as an example. The price is less than 100 yuan on the low-priced market, while a good-quality set costs two to three hundred yuan. Especially for imported brands, the price is as high as four to five hundred yuan. This difference is four to five times. Of course, what is even more chaotic in the market is the use of counterfeit imitation hardware to pass off as imported hardware, which makes customers even more frightened and spend money without buying the real thing.

6. Glass glue: When installing broken bridge aluminum doors and windows, some people use sealant for caulking that costs two or three yuan a piece in order to save money, while some people use it to save money. To meet the quality requirements, the structural glue used on the exterior wall costs 18 yuan or more than 30 yuan per stick. As a consumer, do you want to use two or three yuan of glue each in order to save money? Or use a better quality structural adhesive for the sake of quality? Of course, the mid-range brand of exterior wall structural sealant that costs more than 18 yuan a tube used by Yun Zhicai’s editor is not charged separately and is included. It will not increase the customer’s cost because of the use of good glue.

2. The production process of broken bridge aluminum doors and windows

A complete set of production equipment in a small workshop only costs 70,000 to 80,000 yuan; while a large factory only has a high-precision double-head saw It amounts to 60,000 to 70,000 yuan. This kind of investment is not because the big manufacturers have money, but because their cutting accuracy is indeed not at the same level! This is just one device for comparison, there are several other devices! Therefore, the investment in large factories is large, while the investment in small workshops is small! When a product is produced, which one do you think has the best quality? High accuracy? To produce good products with quality standards, the hardware investment must first meet the standards. Only when the hardware meets the standards can we produce products that meet the standards, and the cost will undoubtedly be higher.
