With the current market, integrated doors and windows are becoming more and more popular. Choosing aluminum doors and windows has become a headache for every home decoration. Let’s take a look below. Those brands on the market that are relatively cost-effective. :

For aluminum doors and windows, the brand is very important, and the production is even more important. There are too many broken bridge aluminum brands on the market, and the number is dazzling. How should we choose from so many broken bridge aluminum brands? ? The prices of different brands of broken bridge aluminum doors and windows vary greatly. Today, the master will tell you which brand of broken bridge aluminum should you choose? Don't waste your money on off-brand aluminum.

The bridge-broken aluminum brands currently on the market are mainly divided into two types: one is well-known brands and unknown brands, and the other is self-created brands. The bridge-broken aluminum brands we refer to are often referred to as Aluminum brands, such as Feng aluminum broken bridge aluminum doors and windows, are broken bridge aluminum made of Feng aluminum aluminum.

1. Well-known brands: Well-known brands of broken bridge aluminum doors and windows mainly include Fenglu, Zhongya, Xingfa, Jianmei, Jinpeng, Nanshan, Asia Aluminum, Weiye, Weichang, Xinhe, and Luopu Sijin, Minfa, Guangya, Guangzhou Aluminum, Huajian, Dongliang, etc., these are all well-known aluminum brands, but the really good bridge-breaking aluminum brands in the market are only the first few. For example, many well-known brands such as Feng Aluminum, Zhongya, Xingfa, and Jianmei have never been heard of by many consumers.

What are the benefits of choosing brand broken bridge aluminum materials? At least the material quality is more guaranteed. The wall thickness of the broken bridge aluminum materials produced by large manufacturers will be produced in accordance with the national standards. Whether it is wall thickness, paint film thickness, material flatness, and gloss, they all meet the national standards. In terms of materials, consumers can feel more at ease. They will not worry about quality problems with the aluminum, or that the aluminum is too thin and not strong, etc.

2. Unknown brands: This is what we call broken bridge aluminum materials produced by small factories. Such aluminum factories are mainly distributed in Shandong, Hebei, Liaoning, Jiangxi, Hubei, Guangxi and other places. At present, the unknown bridge-breaking aluminum brands on the Beijing market mainly come from Quito, Shandong and Hebei. The materials of this type of brand include national standard materials and non-standard materials, that is, they can be produced in any specifications and wall thicknesses that customers need. , which is completely tailored to produce broken bridge aluminum materials according to customer requirements, rather than strictly producing according to national standards. This type of aluminum material factory can provide 1.2mm or even thinner material production, and can also OEM. For example, if you want a German company If a certain brand is used, they can label it a certain German brand.

3. Self-created brands: refers to brands created by manufacturers themselves. Door and window manufacturers purchase aluminum materials and then paste their own trademarks on the aluminum materials. Door and window brands are well-established domestic brands. There are: Meritor, Philharmonic House, Yangyi, Moser, Senying, Shubiao, Liangmudao, Xinbiao, Huangpai and so on. In addition, there are also some small factories that create their own brands, such as brands with "De, Ka, Dun, Sri Lanka, Wei, Ge, Lang" and so on. Many of them are small factories, and the aluminum It is difficult to guarantee the quality of materials. According to some so-called "German brands" that the editor has visited, I found that many of them have broken bridge aluminum materials with several wall thicknesses. The national standard wall thickness is 1.4mm. Several manufacturers I visited found non-standard materials that were lower than the national standard, and the wall thickness was only 1. Amidst the wailing sounds, the math teacher walked in with a stack of test papers.

It seems that because of the cold weather in winter, the physical education teacher caught a cold.

So it became two math classes and a test at the same time.

The math teacher’s name is Ou Dao, a very mathematical name, with black-framed eyes all year round.

Papers are being distributed one after another.

As a poor student, Su Mu reluctantly took out the mathematics reference materials and wanted to try his luck to see if he could find the original question.

"Ding! I checked the math questions, math points +1, current points 1/100, level: Level 1"

Suddenly, a voice came out of my mind. He was so startled that he almost fell off his stool.

The tablemate Yan Xiaoke on the side couldn’t hold back her laughter.

Ou Dao glared at Su Mu fiercely.

"?..."

Su Mu's eyes widened, a little in disbelief.

"What the hell is this? Is this a system? Is there really such a thing as a system?"

Su Mu continued to flip, and the same sound appeared again.

"Ding! You checked the math questions, math points +1, current points 2/100, level: Level 1"

He just glanced at it and actually increased the points. ?

Su Mu felt that his mind was clearer.

These unfamiliar mathematics questions seem to be somewhat familiar.

He became more and more excited.

These are the changes that really appeared before his eyes!

Su Mu flipped through the book faster and faster, and his points accumulated more and more. It was not until Ou Dao came over and stood in front of him that he realized and quickly took it back.

At this time, his points have reached 81/100.

He did not panic, but continued to check the questions on the test paper.

Finally, the system received a new prompt sound.

"Ding, your math points are enough, level: Level 2, current points are 0/1000!"

At this moment, Su Mu seemed to be enlightened. Mathematics problems seem to have become friends for many years!

He is!

I understand!

I understand! !

I actually understand it! !

Su Mu's heart suddenly burst into tears, and he felt that all the hardships had come to an end.

As if to test his results, Su Mu's mind was completely silent on the test paper. This was a scumbag's desire for knowledge.

Time passed bit by bit, and even Su Mu himself didn't notice it.

Unfortunately, although his mathematics has reached Level 2, there are still some questions that he cannot solve.

"Ding..."

This time it is not the system's prompt tone, but the bell for the end of get out of class.

This was the first time that Su Mu felt that time passed so quickly.

The two hours that were once so long still left him feeling a little unfinished.

Is this what it feels like to be a top student? He thought silently.

Su Mu felt that he should have scored 103 on this test paper.

Because he didn’t know the questions he didn’t know.

As for those simpler questions, Su Mu had a kind of mysterious confidence.

The answer he came up with must be the correct answer!

......

"I'm going to study hard."

Suppressing the excitement in his heart, Su Mu corrected himself
