I bought two of these for my food pantry. They are holding up well with a great deal of weight from canned food. I have other shelves that have sagged due to weight but these are so strong I don't have to worry. They are well constructed and assembly was not hard, but it is easier with two people only because they are so big. Last but not least, the paint finish is holding up very well and I see no signs of rust, at all. If you're looking for strong, we'll built shelving, then these are worth the investment.
