Are there aluminum extrusions available for the side door ?

I'm having a hard time comming up with a good design for my side doors!! I would like to have an aluminum frame, as well as an aluminum edge on the door. I want my tear to look like it was factory made. I know that overlapping the door is an easier way to do it, but I like the looks of a flush side door. Thanks, Dan
