Help with finding low fence-like barriers

Hi,

i was planning on upgrading my tortoise's habitat because she's growing and this one is getting too small. I was thinking of finding and buying something like a low, metal "fence" that wouldn't be taller than ~30 cm. I've looked on Temu to try and find something cheap because I'm a minor and parents are providing money and they weren't with the idea of upgrading, but the fact she's suffering in a habitat that's too small for her is eating me alive. I'll try once again, and thought they would like this idea more, because it's simpler.

Have you got any ideas where i could find something like this? The enclose is inside, holes shouldn't be too large. Height is max. 30 cm. Delivery should be available to Croatia.

I included a picture of what i had in mind, would anything like that work?
