Using PFC unrestrained over 3m

[Deluks]

Would there be any issues using PFC 200x90 over a 3 metre span with thin air underneath and 600oc trusses on top?

Actually it's 2 lots of 6m, but the centre and one end will be picked up by a steel column.

Roof covering, probably osb/ply/felt (yes osb AND ply) Might yet go with steel box profile instead of felt.

Just to confirm, single pfc, not back to back.
