Robertson & Inryco Deck

Robertson & Inryco Deck

Robertson & Inryco Deck

(OP)
I would appreciate any information (load tables) for the floor deck in an old office building that I am trying to find the load capacity for (see photo). They used two 17" wide deck pieces between a 26" deck piece for electrical I'm assuming. The plans list two alternates:

17" N-22 / 17" N-22 / 26" 26NF-20-20 Inryco deck with 6.25" total thickness (deck + concrete)
OR
17" QL-21-22 / 17" QL-21-22 / 26" QL-NKX-20-20 Robertson deck with 6.25" total thickness (deck + concrete)

They have 3" flutes and are spanning 10'...

I know there is some information on Robertson decks when I search here or use Robertson's website, but I cannot any load tables for the QL-21-22 or QL-NKX-20-20 decking? Also, I can't find anything on the Inryco decking?

I guess I did find information on the QL-21-22 on Robertson's website, but I still have nothing on the other deck types....

RE: Robertson & Inryco Deck

I have an Inryco Composite Slab Design Manual 21-13 catalog from 1980, but the pans are at 8", 12", or 16" spacings, not 17" or 22".

M^2, the pans are at 8" o.c. They just used a 17" wide piece of deck with 2 pans per piece of deck...
