I'm considering using Unistrut for my wall shelving. It's used a lot in industrial commercial applications and has tons f bracket options, etc.
I thought about screwing the Unistrut to the wall studs and making o buying my own shelf brackets,
Anybody else used it for their garage shelving?
Well, you don't specify what you will be putting on those shelves.
That said, I would use this product before Unistrut:

It's all made in USA and available at Menards in my area.
Just put the hang track along the top plate for the whole wall.
Then put the wall standards wherever you need it. They make couplers to join them if needed. Put some blocking in the stud cavity to hold the standard if it doesn't line up with a stud.
Brackets are offered in several depths and styles. The supported brackets will hold lots of weight.
Bend up some shelves.
That's what I did, but I used 20ga galvanized.
Unless you are getting it for free, the Unistrut hardware will cost you a small fortune. And then you are still using Chinese nuts and bolts to put it all together, unless you find USA stuff.
I used SPAX screws to hold my Sterling hardware to the wood. Made in USA or Germany right on the box
Picture isn't my garage, but I did the shelving.
Not "cheap"- about $300 in hardware and metal. But, it won't warp or absorb oil. And, you can take it down easily.
The hanging stuff is another little project. That was about $600 in hardware (strut and rod not pictured). The shelf along the back is just over 20' long, and each side comes out almost 8'. About 144 square feet of shelving.
