I have several of these solid steel bakery racks for sale. They are dirty, but solid. They would be great for shelving on a farm, seed starts etc. I have many old baking sheets for sale for $2 each that can be used as shelves. The racks are about 6 feet tall and they fit the baking sheets from either end. A baking sheet is roughly 24 x 16. These have a footprint of 24 x 32 ish
