There are many things in life that we often see and use, but when we hear the professional terms, we don't understand what they are. For example, the glued corner joint in system doors and windows. People who haven't experienced one or two renovations generally don't get it. Many enterprises regard the glued corner joint as a selling point and highlight to showcase. So here comes the question, what exactly is it? Which part of the door and window is it installed in? Why are major merchants trying their best to showcase it? Let's get to know the glued corner joint from the following three aspects with these questions.

The glued corner brace is a connecting piece used for door and window assembly, mainly composed of the corner brace body and the glue injection holes. The corner brace body is usually made of aluminum alloy, which has the characteristics of high strength and corrosion resistance. Its shape is a right angle, which can accurately match the profile cuts of the door and window frames and sashes. The glue injection holes are the key design of the glued corner brace. They are distributed at appropriate positions on the corner brace body, providing a channel for the subsequent glue injection operation.

In actual use, the corner connectors are embedded in the profile cavities of the door and window frames and sashes, and are initially fixed with screws to form a basic connection framework. Subsequently, special corner - joining adhesive is injected into the gaps between the corner connectors and the profiles through the glue injection holes using glue injection equipment. After injection, these corner - joining adhesives will quickly fill the gaps and solidify in a short time, firmly bonding the corner connectors and the profiles into a whole, greatly enhancing the connection strength and sealing performance of the doors and windows. They are widely used in various building doors and windows.
