Expanded sheet metal is a sheet product that has been slit and then 'pulled apart' or stretched to create the diamond shaped openings. Our Expanded Aluminum sheet comes in two sizes, both are flattened. If you need more options we stock several more sizes in Steel expanded sheet metal, all of them also flattened except for our 3/4" pattern which is raised.
