Is there an online resource for metal panels used for mounting glass for wall hanging? I see Hang Your Glass has some "coming soon". If I knew a local metalworker he/she would already be my best friend.

We have a local commercial hvac company which has all metal fabrication equipment as well as sheets of various metals. They have sheared sheets of theirs for me in the past. I believe you are near Knoxville, so there should be several similar companies there.

Alaska copper and brass has several outlets. I would give them a search.
They handle all kinds of sheet, rod and pipe metals.

I purchased a large sheet of aluminum (4'x8', i think) from a local metal company, and they cut it up for me in various sizes. I have enough to last me for quite some time, but those 30-some odd sheets I got were significantly less expensive (as in 10x) than buying what is being sold retail.

Dana, Did their cutting method leave smooth edges? That is a concern I had about going to metal shop.

They are very smooth (no burrs), but not rounded. I sand down the edges with a little sand paper, just like you would to take the edge off sharp glass.
