Which type of pvc for racks?

Been looking into building a pvc rack for a couple ball pythons. But am clueless as to what kind of pvc im actually looking for. I have 3 home improvement stores that sell pvc panels. Are any of these sheets suitible? And if so which one would you choose.

You want 1/2 expanded pvc or controlled density PVC.

I can't even seem to find PVC sheets near me. Home Depot near me says they are not in stock, they can't be shipped to me, nor are they available for order and store pickup. The other site you listed (Menards) shows estimated shipping of $247.72... I just don't see a possible way for me to even get the materials without spending way more then buying one from Animal Plastics, even with shipping.

Have to buy from a local plastic supplier.

Instead of using sheets, I use these PVC boards. Readily available at Lowe's (I'm guessing if you have a Home Depot and Menards, there should a Lowe's reasonably close?). I would guess also at Home Depot, but not sure. They are in the outside siding/finishing area near lumber.
