Hammered nickel and distressed steel... it reminds me of an iron foundry (or something that would be in Lord Iron's house in Michael Moorcock's Silverheart)
He has a number of other interesting designs.
Some very industrial looking...
Others a bit more rustic...
I really like this look -- trying to do something similar would be great for a fridge (more on that soon!), or a wall.
The site also has fireplace doors and screens, mailboxes, switchplates, and more fun things, but these were the most steampunk looking of the bunch.
