[0002] Plastic steel profiles and doors and windows are important components of modern buildings, and are a kind of composite material integrating the advantages of plastic and steel. They are widely used due to their aesthetic appearance, durability, energy saving and other characteristics.
[0003] According to the related technology, the existing steel profiles and doors and windows usually adopt various methods to improve their strength and stability. For example, a common method is to add reinforcing ribs or reinforcing plates inside the profile to increase the overall stiffness by increasing the material thickness or changing the cross-sectional shape. In addition, some design schemes adopt different types of connection methods, such as welding, adhesives or mechanical connections, to enhance the connection strength between the profiles.

In particular, in some key parts such as the middle support, due to the limitations in design and production process, the strength is still insufficient. This makes the profile prone to deformation, cracking and other problems during actual use, seriously affecting the overall stability and service life of the door and window. Therefore, how to further improve the strength of the steel profile, especially the strength of the middle support, has become a technical problem to be solved. CONTENT OF THE INVENTION
