Many customers pay more attention to the size of the broken bridge aluminum door and window profiles, the origin of hardware, the quality and price of large components such as glass manufacturers when choosing to seal balconies with broken bridge aluminum doors and windows, often ignoring the splicing method of door and window corners. However, in reality, the strength and stability of broken bridge aluminum doors and windows are not only related to the door and window profiles, but also closely related to the door and window assembly process. Usually, a complete broken bridge aluminum door and window needs to be assembled from frame and leaf structural profiles, and the key to connecting profiles is the splicing of their corners (i.e. using corner brackets to rivet two profiles together at a 90 ° or 45 ° angle). The corner assembly process of broken bridge aluminum doors and windows is also called corner connection process. these aluminum triangle brackets use extrusion process in Fine Processing, which is also use powder coat paint. these products used 6063 in the Metals And Alloys. Meanwhile, we also provide custom aluminum extrusiond basis to your drawing.
