We're renovating and adding on to a building built in the 60's and the roof deck spans almost 27'-0". I'm concerned about drifting snow that our addition may add to the existing roof. Does anyone have information on this metal roof deck. It is 7 1/2" deep ... I'm assuming based on the callout that it is 16 ga deck. I can't seem to find any info on this so any help would be appreciated.

I've got a old Robertson Catalogue. It has a DC and ADC 7.5 roof deck that's made up of two sections welded together. There's eight combinations of 18, 16, 14 and 13 gauge plates. If it's 16/16, the top Sections Modulus is 4.56 in^3 for a 24 inch wide section and the bottom is 4.92 in^3. See the attached scan.

Thanks for the quick responses and for the scan from the catalog. The decking is very similar to this except that there is no pan at the bottom. Each inverted U shaped section of deck is connected at the bottom and you can see the voids from below ... it is very similar to Deep-Dek 7.5 by the Metal Dek Group. Is there anything else in the catalog without the 24" wide pan at the bottom?
