Process characteristics and outstanding advantages of steel-plastic coextruded doors and Windows

Process characteristics of steel-plastic co-extrusion doors and Windows:

The main technical feature of the steel plastic co-extrusion doors and Windows is that the doors and Windows are tightly screwed with the steel lining at the four corners of the frame and fan using special plugings such as 1.2-1.5mm thick corner core plate, and the end of each stressed rod is regarded as a fixed end support, and the bending moment can be distributed to the connected rod when the rod is cut by wind load, thus effectively improving the wind pressure deformation resistance of the door and window.

At present, the stress rod of plastic doors and Windows popular in the market is a plastic profile, an interpolated open steel lining, a plastic profile welded into a window by the corner, and the steel lining is not connected to the steel lining. It causes severe deformation and lack of strength of the plastic steel window. As shown in Figure 2, the structural mechanical differences between the two materials are extremely obvious, and the strength and rigidity of steel are many times stronger than that of plastic profiles, and the advantages are very obvious.

The outstanding advantages of steel-plastic co-extrusion doors and Windows:

(1), no deformation, good rigidity

The deformation of doors and Windows is the most headache for users, and the deformation of doors and Windows mainly has the following conditions

(2) Plastic deformation

If the solid belly steel Windows and unmodified wood doors and Windows have been eliminated, the deformation of inferior plastic Windows is more obvious.
