I've never seen checkerplate that thin before. I think the thinnest was 1/16". Even that was just paper that you can very easily bend with your hands. You can find alum that thin; but it wont be checkerplate.
Would 1/16" not work?
What is this going to be used for anyway? Id offer some suggestions; but without having any vague idea of what the project is I really cant help.
