Angular strength is one of the most important performance indicators for evaluating the quality of doors and windows! Door and window corner codes play an important role in doors and windows.

In the building environment, doors and windows are subjected to various forces, such as opening impact, wind pressure, temperature change stress, etc. The connection angle strength of the frame is insufficient, which can lead to corner opening and connection deformation, losing the basic frame retention ability of doors and windows, causing problems such as door and window leakage and inability to open normally, seriously affecting the sealing and safe use of doors and windows. Door and window corner codes maintain the basic frame stability of doors and windows, which is a prerequisite for all performance

      The frame and fan assembly angles of system doors and windows are generally connected at a 45 ° angle. There are at least five ways to connect door and window corner codes at a 45 ° angle: screw splicing, rivet splicing, extruded splicing, pulled splicing, and expanded splicing.

       Door and window frames, as well as sashes, are generally assembled using a 45 ° angle docking method. During assembly, corner codes are inserted into the assembled frames and sashes, and after inserting the codes, corner glue is injected. The connection between the corner codes and the frame and sash profiles is fixed. Currently, the vast majority of manufacturers use corner machines to squeeze the corners of the window sashes. The function of corner adhesive is to firmly bond the corner code and aluminum profile after the corner assembly of aluminum alloy doors and windows, assist in reinforcing the bonding force in the corner area after punching and riveting, and eliminate stress concentration at the punching and riveting points. Make the corner code firmly and reliably bonded to the aluminum profile.
