The bulk of the storage area is ceramic or porcelain tile, in wrapped boxes, on wood slat pallets.
However there are “some” vinyl floor tiles (packaged the same way) and “some” rolled rugs and carpet squares.

The Chapter 13 only covers plastic to storage to 5 ft in dedicated storage facilities or Miscellaneous Storage of Plastics to 12 ft. My understanding is that the area in question is designated for storage (ie. it is a 4600 sq ft warehouse area), so for plastics to 12 ft on racks you need to go to Chapter 17.

Roof is at 30’ and they want to store to 20’. They will have vinyl flowing and rolls of rug and carpet, as well as ceramic and porcelain tile. I believe I have determined that the vinyl and rolls of rug equate to Group A, non-expanded plastics. My question is this … is it permissible for the client to storage all their group A plastics on racks UNDER 12’ and their ceramic floor tiles on the racks OVER 12’ and to then calculate the roof system for the lesser, ceramic tile storage?
