What is the weight limit of this steel?

[Malcolm Schweizer]

By my calculation, each pallet is 60 lbs x 64 bags = 3840 pounds not including pallet. Imagine the stress on that steel and on those bolts holding it to the floor.

The bolts holding everything to the floor aren't stressed at all-
MY amazement is that each shelf is supported by a 2x2" steel post, full of holes no less, with 2 bolts/rivets per shelf:

But even plain old grade 5 bolts are really strong, with a shear strength of over 70,000 PSI...

[Adam Herman]

the posts are more like 4 in wide. and the 6 in tall cross beams are rated for something like 9k lbs per pair.
looks like 4 ft. between cross beams, so should be rated for about 20k lbs each leg. not knowing the specific diminsions and manufacture.

i think the home depot ones have 2 pegs plus the one that locks it in on each end of each cross member, so thats 12 pegs per shelf in shear.

That isn't something to be close to during an earthquake.

Athough I am sure different brands have different ratings, I looked up a few and this was the most industrial one I found. In this case it would be overloaded.

As for the bolts holding it to the floor, as long as it is perfectly vertical, they aren’t under stress, but bump it with a forklift and tilt it ever so slightly, and it’s a whole different story.

Just takes one bump in the right place…

I think those were bolted to the floor. But, no connection at thetop level to tie them together.
