How to reinforce a screen on a steel door?

[Country4ever]

I have a steel door on my coop with a window that slides up and has a screen. I put a couple small spring tension rods behind the screen and some hardware cloth but a coon could push it through, I'm sure.
I never really worried about it before, but since I've had a coon attack, I realize I've been underestimating their abilities. Any ideas on how to make that screen window safer? I hate to close it in summer, because it helps with a breeze.
Suggestions?

I would replace the screen with hardware cloth. Use metal screws with washers to install it.. even coons can't get through properly installed hardware cloth.

Do you mean to drill holes in the steel door?

Yes you can drill holes and use a washer and nuts, use washers on both sides.

I'd build a wooden frame to hold the HW cloth, and use self drilling/tapping hex head screws to attach the frame to the door
