Pet Bird Magazine, Ezine August 1997 Magazine . I'm writing this to share the knowledge I've gained about zinc and the process of galvanizing. If it is coated with something else then it is anodized or plated. Galvanized implies zinc. The two most common methods of galvanizing are electroplate and hot dipped.
Sheet metal is usually electroplate.
This is a thin shiny finish with a criss cross, crystal looking pattern, like frost on a window. Wire is usually hot dipped, it's a thicker coating and dull in appearance. What is cheap and easy to find at the hardware store or home improvement store, is that screen looking stuff that comes in various sizes. It is called hardware cloth, and it is a grucky hot dip. It works fine for rabbits and chickens.
