Open mesh floor

I've got a mix of mesh types and would like to check which are stainless steel and which aren't … any clue how to do this? The black epoxy coated stuff is obvious. The galvanised mesh sold by Thorne's is also obvious. However, I've got some that looks like the stainless stuff linked in the email from Kitta but I'm sure I'm sure I didn't pay stainless steel prices.

I have all 3, the epoxy coating seems a reasonable cheap option, the galvanised mesh can't take the varroa chemicals and has lost the zinc coating in a year and will need to be replaced. Stainless is still ludicrously expensive

If you get SS in bulk from the company Kitta linked to above it becomes slightly less eyewateringly expensive. I'm thinking of splitting the costs with friends.
