Thanks Robert.
I have the dimensions and section properties.  I will only be using it for axial tension members only.  So, all I need is a conservative estimate of allowable tension stress.

Try Allied Tube.  Also, you can get dimensions of EMT from the McMaster Carr website or the Grainger Catalog website, and calculate your own section properties. 


I frequently design miscellaneous struts from EMT as you are doing.  I conservatively use 20 ksi allowable bending stress, but usually column buckling controls and the actual stress is much less.


I like the stuff because it is very ductile - it has to be so Sparky can bend all those offsets and such.

Does anyone know where I can find the structural properties for EMT tubing?


It is proposed for use as duct support and bracing.
