Ugh! All these questions.

Galvanized is zinc coating on steel
Non anodized the aluminum oxides and rubs off black
Anodized is chemically oxidized and makes a hard (and dyeable and durable) coating that has a stronger surface than plain aluminum. That's why they use it on pretty bicycle parts and cookwear
