Yes, there is a roof deck above that is sprinklered. I have put
sprinklers below the grating using shields on the sprinklers. Just
second guessing myself.

We have used stove bolts with a large head and a long thread. That minimizes
the possibility of a trip hazard as there is only a small bump on top of the
grating.

What are everyone's thoughts on the above?
It is being used to comply with 50% open for "open rack".
However, it seems very much like fiberglass-reinforced polyester. (Group A,
nonexpanded)
Even comes up under a search.
So then comes the Class jump question due to presence of plastic pallets.
Thanks everyone,
It is actually considered an open grid ceiling (Thanks for directing me to
Sec.8.15.3).

George,
I believe it's all grating. The dimensioning of how much covered to
open area and size of openings is for egg crate ceilings.

I think NFPA 13 differentiates between steel grating and open-grid ceilings
due to the very real potential that steel grating can have something placed
on top it to create an obstruction - such as some type of storage, plywood,
