I have something very similar to that for my rolling shelves. Its great cause you can put the shelves where you need them. The shelving themselves hold a lot of weight with no problem. We also have them in the deli I work. Have about 400 lbs worth of meat and cheeses on multiple shelves and the store has been open for about 14 years now, using the original shelving. At home, I put the bulkier items on those types, like my five gallon buckets, oils, coffee cans, ect.
