FyrePLATE: Cast in Collar Adaptor Plate for Steel Deck Floors

Home / All Categories / Product Ranges / Fire Rated Sealants / FyrePLATE: Cast in Collar Adaptor Plate for Steel Deck Floors


Traditionally, cast-in collars are nailed down to the formwork before the slab is poured, this can cause issues for permanent metal deck systems such as Bondek, Truedek, Kingflor, etc. There isn’t enough flat space to mount a collar, and the location of the required service may fall on a tricky spot on the deck.

For these situations Trafalgar has a fire-tested solution; the FyrePLATE is an adaptor for the FyreCOLLAR Cast-in High Top system that will suit any steel deck system with a profile up to 70mm deep and can locate the service in any required position in the deck.

Bend the FyrePLATE to suit the deck profile and fit it over the cut-out in the deck. Fix the FyrePLATE to the deck using 4  tek screws and use reinforced foil tape to cover any gaps >5mm to reduce concrete ingress. The system is ready for the concrete to be poured, the pipes can be run through the collar before or after this happens. Follow the installation steps in this manual for installation and other details.
