With good prep and paint it will last a long time. The key to painting
aluminum is to seal off the aluminum, kinda like a coat of shellac on problem
wood.
Best methods come from the aerospace industry, zinc chromate primer followed
by a urethane type paint (Imron is my favorite). Not something you usually
can do at home without a lot of preparation.
Anodizing can be pricey and you would get the best results if done after
making all the cuts, otherwise you could buy pre-anodized strips and figure a
way to blend in the areas where you disturb the surface.
If price is secondary, brass or copper would look nice and it would 'age'
with a nice patina. Steel, although cheap, would require something like a
chop saw to prep, but it also can be painted (think automotive paints) or
with some creativity can get a nice patina with gun bluing techniques or
heating with a propane torch to get some neat colors (then clear coating).
