Fire colar for flexible floor

Do you have a fire collar suitable for use within a 60-minute fire-rated flexible floor construction comprising light gauge steel framing sheathed with two layers of 15 mm Type F plasterboard, with 22 mm OSB boarding above?
We are looking to achieve a 60-minute fire resistance rating for a pipe penetration through this floor build-up and would appreciate details of any tested and certified collar systems you can offer for this application.
