What is the difference between them? There is a big difference.

What is a broken bridge aluminum door and window?

Broken bridge aluminum is also called thermal insulation broken bridge aluminum profile. The essence is aluminum alloy window, which is added with a thermal insulation strip in the middle. Because aluminum alloy is a metal, heat conduction is relatively fast, so when the indoor and outdoor temperature difference is a lot, its heat insulation performance is not good. The broken bridge aluminum is the aluminum alloy is disconnected from the middle, it uses heat insulation strips to connect the disconnected aluminum alloy into one body, we know that nylon heat conduction is obviously slower than metal, so the heat is not easy to pass through the whole material, the heat insulation performance of the material is also improved, this is the name of "broken bridge aluminum (alloy).

broken bridge aluminum doors and windows are not only heat preservation and heat insulation, but also fire prevention, anti-theft, sound insulation and anti-dryness, high comprehensive performance, long service life, good decorative effect, more and more favored by consumers. But now the market is full of various prices of broken bridge aluminum, 500 to 1000 price of the majority. Some people ask, what is the difference in this price? What is the difference between them? The difference can be as big as

. What are the differences?

The black sealing strips of 1. connecting profiles are different

. In order to attract customers to buy at a cheap price, some manufacturers use PVC material instead of PA66 material (nylon strip) in the middle. PVC costs only a few thousand yuan per ton, while PA66 is 20000 yuan per ton. It is estimated that the price difference per square meter is 50 yuan.

2. profiles have different purity, width and thickness.

primary high-purity aluminum ingot produces windows with higher quality than recycled aluminum and impurity aluminum. The primary aluminum ingot section is high gloss, and the recycled aluminum section is dark.

and the thickness and width of the window are different, the 100 profile is definitely a little wider than the 90 profile. Broken bridge aluminum window minimum thickness of 1.4mm, below this standard can be considered unqualified products. According to the calculation of 6m profiles, each 1.2mm profile is as much cheaper than 1.8mm 70 yuan. (The price difference per flat price is about 70 yuan)

3. hardware accessories are different

. Take a set of internal hardware as an example. 100 yuan cannot be sold in the market with low price, while a set with good quality can reach 200~300 yuan, especially for imported brands, which is as high as 400~500 yuan. According to an average of 3 square meters to open a window, the price difference per square meter is about 150 yuan. Inferior accessories have no code spraying or LOGO. The workmanship and materials can be seen at a glance. The difference can be distinguished as soon as you take them. Good hardware is heavy in your hand.

4. process costs are different

A set of production equipment in a regular large factory is usually in the hundreds of thousands or even millions, while a set of production equipment in a small workshop is only 6 or 70000. Process costs are not only reflected in the equipment, the design costs of regular large factories, utilities, etc., are all small workshops. Reflected in processing costs, small workshops average about 2000~3000 yuan per ton, while large factories need 5000~6000 yuan per ton. The difference is huge.

Correspondingly, the high precision, high quality, and high standards that can be achieved by products produced by expensive equipment are not comparable to small workshops. We can see the huge difference in price, but we can't always ignore the difference in quality. Therefore, the process cost is reflected in the price, usually a difference of 100~200 yuan per square meter is also very common.

There are differences in 5. installation quality

Whether the installation quality is good or not? First look at the beauty, second look at the firmness, third look at the sealant, fourth look at whether the opening is smooth, fifth look at whether the window is properly adjusted. Some installers did not pay attention to it. In order to save time, they did not debug the windows, resulting in unsmooth push-pull opening and serious abnormal noise. This is definitely not possible. Brand doors and windows installation after-sales personnel are through the formal training, the installation of professional level is more secure.

Different sealing strips (50 yuan) Different profiles (70 yuan) Different hardware fittings (150 yuan) Different process installation (200 yuan) = 470 yuan, which does not count the different costs of hollow glass, screen windows, etc.

Why do the aluminum doors and windows of the broken bridge next door only need 500, but some need to be 1000?
