Load Span Tables for 38mm (1 1/2") Wood Plan Deck

Load Span Tables for 38mm (1 1/2") Wood Plan Deck

Load Span Tables for 38mm (1 1/2") Wood Plan Deck

(OP)
Does anyone have a load-span table for 38mm (1 1/2") wood roof plank decking, random length continuous with SPF wood?  I can't seem to find anything for 38mm, all the tables I've found start at 51mm (2").

I have a building with plank decking spanning 6 ft between steel beams.  1 1/2" seems a little on the thin side, but my experience in wood is limited.

Thanks.

Actually, one thing I should clarify is that the original design drawings indicated 38mm wood decking.  I'm curious if this 38mm is the REAL thickness, and not the nominal thickness.  For comparison, most 2" wood decks are actually 1 7/16", correct?  Perhaps they specified 38mm as the real thickness, and it's a 2" nominal deck?

RE: Load Span Tables for 38mm (1 1/2") Wood Plan Deck

38 is the metric equivalent to 2" nominal and is 1-1/2" thick.

Agree with dikk.  Same as 2", 3", or 4" decking -  Nominal thicknesses for 1.5", 2.5" and 3.5" actual thicknesses.

This should work if you are using 20, 30 or 40 psf live loads.
