span tables for laminated 2x4 deck
 

span tables for laminated 2x4 deck
years ago i recall coming across span tables for warehouse floor decks fabricated from laminating 2x4, 2x6 etc. on edge -(nails staggered @ 16" o.c.}
if memory serves me correctly, the spans were quite long when loading was light.
am wondering what can be spanned with a 2x4 roof deck - 20# snow load design factor.
thanks!
