Trunk Divider Panel Board

How would I go about getting like a steel or aluminum version of a trunk divider panel board? where would I get one? I would like a steel one so I could bolt right in.I want to keep it stock but don't want to see into the trunk.I removed the back seats and don't plan on having any. thanks a lot hope to hear from you guys
