If you have typical metal deck, then you have to fill the "flutes" with mineral wool or something similar. Panel construction requires heat doesn't pass over the top of the members. Typical metal deck will allow that to happen if the spaces aren't filled with a noncombustible material.

I have a room with exposed deck ceiling, the framing is wide flange beams about 11'-0" on center. The walls of the room will section the beam pockets into areas less than 300sqft. I can still consider this obstructed construction. Jerry Van Kolken Millennium Fire Protection Corp. 2950 San Luis Rey Rd. Oceanside, CA 92058 (760) 722-2722 FX 722-2730
