metal objects

i would like to make wallmount for torches and chandelier and banisters and iron doors in to different metals
like copper or silver chandelier would be nice
think it is not too difficult to do
it works with wood
oh and iron chests too
and metal windowframes and stairs
and not to forget metal planks and beams like wood
same for plaster and concrete(planks and beams)
hope this will be added in the game
