I going to run 1/2" EMT conduit on the bottom of a joist. The standard straps I have are too wide to get both nails/screws in. I would prefer to run the conduit down the center of the joist. I wouldn't be able to do this with a single nail/screw strap. I was thinking of using a thick metal tape with holes every inch or so in it. I have some holding up my gas line. Do they still make it? If so, what is it called? Or could I used plastic zip lock ties instead?

I would not use EMT at all. It is not weatherproof. Those compression couplers (you know, the not-setscrew ones) are not for weatherproofing, they are for better grounds. I would either go with thickwall with threaded connectors which I would teflon or dope for watertightness, or preferably PVC, which is cheap and easy to work with.
You want a PVC-to-threads adapter as depicted below (presumably 3/4" to match the size of the knockouts on your box, with a 1" to 3/4" PVC reducer used to adapt the LB's 1" to the adapter's 3/4").
You then use PVC from the LB to the adapter/reducer pair, and a locknut to hold the adapter to the box.

It is called perforated strapping and it comes in steel or a plastic material. That would be OK to use.
