3000LBS Storage Shelves,48" W Garage Shelving Heavy Duty Metal Adjustable Garage Shelves, Shelving Units Industrial Shelving for Warehouse,48" W x 24" D x 69" H,Black

This item comes in many pieces. Material is mostely Roll formed steel . The shelves have a spot welded stiffner on the bottom. The unit assembled without any trouble using a Phillips screw driver supplied . However I had a problem with the diagonal braces on the end legs. When assembling the diagonal brace the end legs become Trapazoidal . I read the instructions several times and “counted holes” but nothing worked. I finally just used the bottom screws only and let the brace seat against the upper horizontal brace and put the bolt in the hole to keep the brace in place . The last picture shows the bottom shelf with steel wheels,brake drums,brake rotors stored and it seems to hold up ok . There are no provisions to bolt this unit to the floor but these can easily be made as there is holes available to fasten to . BH

EDIT: the company reached out to me and we negotiated a partial refund in lieu of a return. Original review will be tweaked to be more fair in light of this.Do not buy. No matter how flimsy other reviews led you to believe it was, trust me, it's flimsier than you imagined. I didn't get two minutes into unboxing before I found sheet metal shelves with egregious bends in their corners. I started a return, only to find I'M liable for return shipping on this heavy package. Instead, I had to send the seller a bunch of pictures of my damage and settle for a partial refund.Assembly was possible, but the through bolts had a tough time fitting through both ends of the warped uprights. It would benefit the assembly process immensely if try would switch to square openings and carriage bolts. The end result is ugly from all the bent shelves. Oh well, it's just going in my equipment shed.Mind you, this "5000 lbs capacity" shelving unit is built from the same gage of sheet metal as a residential AC duct, so even an undamaged unit deserves to be returned on grounds of gross misrepresentation of the product.

I work in a factory and let me tell you this is put together and built the same exact way the shelving that holds 40,000lbs at work is! The shelves themselves are thin metal but we put several 3d printers on them and they are stable and very strong! I have not one complaint with this! It was a little complicated to put together at first but once you had one side down the other was so simple. If you're looking for a very heavy garage shelf maybe not this one just because of what the shelves actually are, sheet metal, but they also make shelves with heavy duty grates that would be perfect! Amazing size for exactly what I needed and I gotta say a great price!

this is a great deal heavy duty. the box is heavy had to unpack to move but that being said once put together you can store a lot on it.

The directions were not easy to follow. I must have taken it apart six times. They could have made the assembly instructions easier to follow but once we got it together it’s a great shelf for the garage.

My original review would have been either 1 or 2 stars because these are not at all as they are made out to be in the pictures or description.For starters, the uprights are not constructed like every other heavy duty shelving unit I've purchased around this price point. Instead you have to bolt them together and the result is an extremely flimsy upright that twists easily and never feels truly secure.The metal is FLIMSY. I mean, extremely flimsy. The photos show how it is comprised of multiple layers and it absolutely is not. It's paper thin sheet metal that has been powder coated to look more stout than it is.The shelves themselves are effectively useless and you can really only hold something that distributes its weight at the very edges of the shelf. Anything heavy you put in the middle will fold the shelf and make it unusable. It's going to take some plywood cut to dimension to make these usable.The idea of these things holding 5,000 lbs. is laughable and in my opinion, downright dangerous.I tried to return them, but the seller wanted to charge me return shipping. Then the seller offered me a 10% refund to keep them. Then the seller finally offered me a 35% refund to keep them which I accepted as I was tired of going back and forth and I'll reinforce them with plywood.I wouldn't buy them again. I think they're valued at about half of what they cost currently and I think it is irresponsible that the seller continues to sell them for this much.

Why did you pick this product vs others?:They were the perfect size for my shed, looked well built

This product is nothing like the picture. Talk about a marketing scam. These pictures and what you get are totally different. That’s what I get for trying to save a buck. If you’re looking for large sturdy shelving stick with Costco or Lowe’s. Their advertisement shows elephants walking on these things. The ad makes it seem like you’re getting those nice sturdy shelves that you see in Costco or Lowe’s.They are so thin and light. There’s no way they hold up to 3000 pounds like the ad says. If you’re looking for some light storage, they’re not bad, but when you look at their ad, you think you’re getting something sturdy. Couldn’t be further from the truth. But for light storage, if that’s what you’re looking for and not to take up too much space then I guess this would be OK. By the time you get them and unpack them it’s too much hassle to send them back, so I just kept them and I’ll find a use for them. Looks like I was scammed. Won’t buy something like this again on Amazon. Cheap China made product. PERIOD!
