Anshan broken bridge aluminum, who made it well?

It should be that Tianyi's family did it very early. I remember that in 25, I went back to Anshan from other places to decorate my parents' house and wanted to use the broken bridge aluminum window. At that time, only his family could do it. Many manufacturers don't know what broken bridge aluminum is. A few days ago, I made some windows, only to notice that Anshan Broken Bridge Aluminum has been made by many manufacturers. After making a comparison, I chose Tianya B for two reasons: first, the quality is the best; second, I feel very kind, a bit like an old friend. The result surprised me. The selection of quality work accessories was better than that I made in Beijing. The professional quality of the installer is very high, and I also think it is Tianyi.
