(steel tubing is available on weekends and evenings too, fwiw)
I agree it's good enough for random aesthetic stuff, but even outdoor stuff is silly to use it for if you care about aesthetics. It really does rust pretty quickly these days. I have plenty of EMT that is 20 years old and not rusted, and plenty next to it that is 5 years old and rusty.
The latter is from different vendors, too. The specs over the years have gotten worse because nobody really uses EMT outdoors without painting it unless they are willing to accept it rusting to crap.
For your case, you could just use pvc pipe, cheaper, bends easier, cuts easier, can be glued directly, will never rust, you don't care about weight limits.
However, if you remember where we started, this article is about "structural pipe fittings" for EMT.
PVC pipe does not survive outdoors, and the failure mode is messy.
"Structural" does not necessarily mean "very strong".
I think we mostly agree here though. I've used EMT for lots of things, and it has never ever let me down even slightly. I have also chosen square steel tubing for (less frequent) cases.
Choosing carefully is the key. When EMT fits, it's great stuff and preferable in many ways.
I hear this in other comments, but I cannot reconcile it with my own direct experience with brittle white PVC pipes.
There are a few grades of white PVC, including Schedule 40. There must be a subset of options which are appropriate for outdoor use.
[Edit: FWIW A superficial web search agrees with me that standard white PVC will degrade in UV. A common recommendation is to use "furniture grade" PVC, or to paint or wrap the pipe to protect it. In this context I'm mostly thinking about options available at ordinary hardware stores, not special order stuff, but apparently there are options.]
Other reasons to choose EMT though: thinner, more heat-resilient, less prone to sag, stronger by thickness, subjectively more attractive.

That is a horrible horrible idea.
