I saw this brand in an advertisement before and heard that it is like the brand used in the National Grand Theater, so I think the quality of big brands can be assured naturally. I learned that the price of Zhi Shang doors and windows is about 700 or 800-meter. This is what my friend uses. I think the color is very beautiful and the material is very strong. You can consider it recommend. Some people say it is 800 yuan per square meter for online check. If it is this price, it should not be too high in the whole industry. At the same time, Zhi Shang doors and windows do have their own manufacturers in Foshan. They used to be engaged in aluminum alloy processing. The products are good enough and reliable.
