Preferably, the second support member includes a first inner support rod arranged on one side of the first oblique support rod, and a second inner support rod arranged on one side of the second oblique support rod.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The steel-plastic door and window profile with double steel inner bodies has a steel-plastic co-extrusion structure, which eliminates the need for an installation structure to connect the first steel inner body and the second steel inner body to the PVC outer shell, and allows for a direct, tight combination that is more stable. The first steel inner body and the second steel inner body are provided, greatly improving the structural strength of the profile. Meanwhile, the PVC outer shell can enhance the corrosion resistance of the first steel inner body and the second steel inner body.
