I bought these about 15 years ago and they were marketed as Gorilla shelves. Each shelf is 4' x 9' x 18" and they break down into 2 units that are 4' x 4.5' x 18"; they're stacked (and made to be used that way). They hold a lot of weight, no problem with 500-600lbs per shelf. They are in excellent condition and always in my air conditioned shop.
