I doubt it's an RMC, there are so many issues I doubt it's them anymore. (Shout out to my 6 1/2 wait for Steel Vengeance this past Monday due to the transfer track not working)
But to answer your question, yes. A lot of modern "wooden" coasters use steel supports with the wood track for better maintenance. Go check out White Lightning at Fun Spot for an example of it. I can see them use the steel supports with the wood track.
