The ability to support the weight of all the canned goods in my pantry is what I appreciate this shelf for. Since this material is stainless steel wire mesh, I wouldn't worry about rusting issues at all. This actually solves our problem as we have stored a lot of groceries in the pantry and we are worried about the wooden shelves that are about to collapse. That's why we finally decided to add a sturdy storage rack to our pantry. I find the price reasonable for storing heavy shelves. It comes with six hooks and the wheel design makes it easy to move from one place to another. In addition, the wheels are equipped with locks to prevent slipping. It also doesn't wobble compared to other wire shelves. Easy assembly and easy to understand instructions. Overall I am happy and satisfied with my purchase. It keeps my pantry organized and easily accessible when I need to get something.
