The sheet metal is a little on the thin side, it is adequate for what I am using them for but not much more. The measurements given in the description were off by 1" on the length and the width which made me have to change my construction project to adjust for the difference. There were no assembly instructions for the shelving which was not a big deal because they are pretty straightforward but they may not be so easy for everyone. There were a couple more minor issues that cost me a couple of hours of extra work that I was not happy with and they were a little pricey for what they are, but everyone is going cheap these days!!!!
