i just installed a pull down stairway in my dads attic and the manufacturers papers states that it has a fire rating = to 5/8 sheetrock. can’t quite remember what that # is though.

I would question how plywood could achieve the same fire rating as 5/8 drywall. A drywall assembly gets its rating from a complete assembly which would consist of fire taping and in some cases fire caulking as well.
A wood pull down is not sealed around the perimeter so how can it achieve the same rating?

i think it’s a play on term so to speak. the manufacturer made the pull down, which they may have treaded, but they didn’t make the gap around it. it just showd up?

I had one that the owner had sheetrocked the bottom of the ladder and put strips of sheetrock over the perimiter. I checked with the state Fire Marshall and in his opinion, thought it would be OK.
The only thing wrong was when I opened it, the the sheetrock strip on the hinged end broke and fell off.
