Is this safe?

I do Brew in a Bag (BIAB) and would like to keep the bag off the bottom of the kettle when I apply heat. I was looking at various Cooling racks and Steamer racks. The Steamer rack has the advantage of being 2.5 inches tall, which I think is useful for keeping the base over the dip tube.

I am worried that even though it says Stainless Steel, this is from China, and for all I know its Nickle plated Lead, with Arsenic.

Any suggestions on what I could use at the bottom of the pot, to keep the bag off when I apply heat??

A small stainless steel colander/strainer?

Yes, Thats what it is. But is this material safe to put in the mash where it's exposed to a slightly acidic environment for 1+ hours.
I am wondering if it will leech anything harmful. The Amazon site says it can rust, which seems odd, and worrysome.

I would believe the review that says "not stainless steel." Real SS doesn't need a nickel-plated coating. I would buy something else that is actually made of SS.
