What are the top ten brands of system doors and windows? Want to know which is more cost-effective?

The top ten brands of system doors and windows are Huangpai doors and windows, Gao Chuang doors and windows, Paiya doors and windows, Xinhaoxuan doors and windows, Xuannisi doors and windows, Feiyu doors and windows, Xu Ge doors and windows, and most of them are Guangdong brands. To say cost-effective, I personally compared two or three brands, and finally chose Gao Chuang doors and windows. Because Gao Chuang doors and windows can be customized by the whole system, the discount is also great. My balcony window, bedroom living room window, kitchen sliding door and bathroom sliding door are all made by their family. Their home provides free home measurement renderings, and the installation is completely free. I don't have to bother with the whole process, and the cost performance is quite high.
