Worst comes to worst...he can buy a box of cheap 3/4" nuts and simply weld em on the top of the end of the bars. Its not great..but it works...most of the time.
weld em upright..on a flat with the hole facing the material.
And he can use them to seperate the supports when the shelves collapse
So when you toss up that piece that breaks the camels..errr stock rack's arm and it cascades down .. you are standing right beside it?
BRRRRRRRR!!!!!
'In the first place, we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the person's becoming in every facet an American, and nothing but an American... There can be no divided allegiance here. Any man who says he is an American, but something else also, isn't an American at all. We have room for but one flag, the American flag... We have room for but one language here, and that is the English language.. and we have room for but one sole loyalty and that is a loyalty to the American people.' Theodore Ro osevelt 1907
1.5x1.5 stock, at those lengths, are not particularly strong, when one starts putting MANY hundreds of pounds on it. Id suggest a simple diagnol brace from the main upright to the front or middle of each arm. The middle would probably be ok, if the brace is at a 45'ish angle. It wont interfer with his loading them up and it may keep him alive and undamaged.
Did I mention I work in factories all over So. Cal, and have seen stock racks, home made ones, collapse like the World Trade Center?
But hey...I was only making observations. Take em or leave em. Shrug
And yes..you can overload anything. Sometimes however..its harder to do when its properly braced or made of the proper materials. Shrug again.

Engineering Bromide: an overstressed system will relieve its stresses eventually. But wouldn't you rather do it in a controlled manner?

You don't even know what he is storing. His rack could easily be filled to capacity with thin wall tubing. Not to mention how heavily he intends to load it.

Then it will no longer be an over stressed system.
It is like the question to ask about medieval Cathedrals "When did the tower collapse?" The ones which remained were the ones which had enough stone piled up to keep from exceeding the stress limits.
