Chrome Plated Steel Construction.
This is a great cooling rack. It is sturdy and built to last. A simple essential in my kitchen. The squares are small so items don't lose their shape. Often times I will place the rack on a sheet pan to bake oven baked fried chicken. It may sound funny, but I also use it to drain and cool cooked lasagna noodles before I put everything together. Of course, it is great for cookies, breads, and cakes.
