The reasonable assembly process is the key to produce uPVC doors and windows with excellent performance. In European bulidings , the connection of uPVC window frame profiles and transom profiles adopts soldering and bolting. Because of its losw cost , convenient operation and firm installation, it is widely used by many manufacturers of uPVC Windows. uPVC windows adopt screw joint, thus feeding fast, assembly easily. There is no need to cut the V-shaped mouth. It's very convenient and easy. It can use the four- angle welding machine with high work efficiency .The strength of uPVC window is much higher than that of welded structure, especially in the cross connection between the transom profile. The high performance of screw structure is more prominent. UPVC profiles with screw joint are not easy to deform when making large windows.
