Historical Robertson Deck Load Tables

[Rabbit12]

I'm in need of a bit of help finding loads for a deck in an existing building. The building drawings are from 1969.

I found the following note on the drawings: "3"x18GA steel deck shall be Robertson QL-21 and QL-NKX, or Inland Hi-Bond 3N or 3NF".

I found this old thread with a link to Inryco deck load tables.

They are 3N and 3NF. Any chance this is the same deck but the company changed names? At any rate, I have 18 ga deck and the load table in the thread is 20 ga.

Anyone out there have existing deck load tables for either of these decks? Thanks in advance for any help.

Bump. Anyone out there have any info?

Go to Slide Rules site. I think he has info on Robertson Deck. It was from a previous post entitled "Robertson Steel Deck (1960 vintage)".
The deck company may now be Robertson Irwin or HH Robertson.

Thanks Ron.

I looked there after you posted but didn't see anything specific to QL-21 or the others you listed.
