Drywall over metal support panel
This might be hard to explain, but here i go. I am almost finished with a remodel of our dining room. The wife decided to have me build all of our dining room furniture with the exception of the chairs. The theme is contemporay/industrial... Wood and brushed aluminum surfaces. The last thing she would like is ultra thin floating shelves made out of brushed aluminum. Perhaps 4-5 shelves going up the wall,3' long. I was originally trying to figure out a good way to fasten a 1" thick shelf to the wall! But now i have a better idea.
My idea is to have a vertical sheet of aluminum with perhaps 1/4" aluminum shelves welded perpendiculary to it.. I could then remove a large piece of drywall, fasten the support aluminum structure to the studs and recover over the aluminum back with new drywall. Once covered, and painted, the wall would look like it is magically supporting these ultra thin shelves.
Is there a way this us usually done, a way to take into the extra volume the backing would need? Is there a diffent way to try and do this? Perhaps something other than a sheet? Tubing between studs?
