I’m gonna be the bigger person here. My apologies if I offended you.
Just trying to give the OP my opinions since I’ve used them before and have seen many others use them without issues.
@gm357 is right. It is not the best choice.
If you wanna know my personal choice for a stand it would be Framing Tech and yes definitely get it stress tested and know potential weak spots and pressure points. Aluminum 80/20 is very light and super strong.
“ All of our designs go through a structural analysis process to make sure that they will stay standing for years to come. If you need any assistance with your design, please reach out to us.”

These stands are typically more expensive than just a good ol’ 2x4 stand and if you want to save money I’d go the 2x4 route.
Metal stands are cheaper, but heavy.
