The corner post are .050" same as the one's I assembled many of years ago, but the shelf supports that used to be .050" is much thinner (almost half the thickness) .028". When the pins go into the groove there is 20 thousands + loose which makes the not stay at the bottom of the hole, like they used to. The pins easily bend on the thin metal and cannot be installed into the slot without taking pliers and straighten them out. I tried using self drilling sheet metal screws to screw them together and it worked somewhat. There is no way the rack will meet it rating like this especially if it's 6 shelves high. The second rack I assembled, I used (2) 5/16" SS washers at the end of each shelf brace held in place by double sided tape, and it makes a secure joint (if you don't loose the washers). The other thing I did was separate the rack into 2 racks each with (3) shelves. This is the second set of racks I have purchased from Sam's within the last two weeks and both were no good. I have purchased and put together many of these same racks years ago before they started building junk. I would not recommend these to anyone, save you time, money and effort they are not worth it. It took a box of 100 self drilling sheet metal screws and a box of 5/16" SS flat washers and two days to put 2 6-shelf racks together where I should have been done with both withing 4 hrs or less. Oh yea by the way the joint to put the top section to the bottom is a joke, don't even try it.

Overall, a very poor design. Will work as a single tear, but you cannot stack it safely without it sliding over the shelves. You can be done, but you have to use bolts to secure it safely. I simply would not trust it otherwise. How are used it as two separate shelveing units and it worked decently for my needs. I definitely would not recommend go with the $200 unit. It’s far more sturdy, although nearly double the size. I should’ve went with the units instead of these.

Good price of $75 for 6 shelves. Purchased on june 2022. The shelves are indeed thin. Putting it together is indeed troublesome since it does need 2 people when building the top side. I'm not sure how it holds the top side securely but it manages to do that. Steel columns are thin compared to other racks I have built in the past from another brand I have bought two and they're holding up after 6 months for commercial restaurant environment. Holds sriracha boxes, mayo, spam, etc.

I'm usually handy at assembly but this one was rough. Assembly instructions should call for an assistant. The joining of the top and bottom is tricky but strong once joined. The rubber mallet was helpful in getting parts to mesh. Now that it is finally assembled I'm looking forward to loading it up.

I have built many different assembled shelving units over the decades. These are by FAR the worst design to assemble (specifically joining the uprights together). It takes more patience than logic to put these shelves together. Spend a little more and get something better to install.

Bought this a few years back to hold storage bins and some tools. This shelving system is a complete joke. It is unsafe as the bottom material that is the shelf warps causing the sides to bow out. We rigged it up with a giant zip tie just to keep the metal frame tight to hold the shelf…btw items on the shelf is under 300 lbs. and each is supposed to hold 600. The entire shelf system we have on it has about 600 lbs total if even that.

These are a super cheap version of the old shelves that Sam’s used to carry that look like these. They are not the same. Very light duty, flimsy. Almost feels like the rails are plastic. I am not returning because it was so incredibly difficult to put together. I do not have a whole lot of faith in putting anything heavy on the upper shelves. Would definitely not recommend.

Shelving is sturdy and easy to assemble

Putting one over top loose more height

Easy assembly and sturdy. I love it
