Storage rack weight capacity

[Sincerd]

So I built this thing, it's probably one of the most useful and used items I've ever made for the garage. Tucked out of the way and very solid, made out of 11g .75x1.5 tube I believe all of the weight is transferred to the floor. The only weight that should be on the framing is the lean, wanting to fall forward. What I'm trying to figure out is what is the capacity of something like this? I figure I've seen thinner products support tons of weight. Figure I'm probably around 2 tons with the thick steel plate on the bottom racks

That is nicely done. No engineer here so no idea on max cap. I abandoned my horiz material shelves and made a wall rack. You could easily unload a portion of your shelves an do the same. The rack with a couple safety chains would secure things. Mine will take 10’. How high is your wall?

Holy storage racks, Batman! Are you storing steel or all 2x lumber? If it's just lumber you have a LOT of margin.

I made these lumber rack brackets and they hold at least 250 lbs. each without any deflection and they're not as beefy as what you built. My guess on yours is probably 300-500 lbs. per bracket without any noticeable deflection.

You would need to give details on how it is attached to the building structure and how that wall is framed. I've read a lot about being careful to not to overload wall studs in bending as they really are not sized and designed for that type of loading.
