I don't understand. I got my reference images from articles showing galvanized aluminum or steel. Naturally I don't know if they're truthful, nor do I particularly know the difference and I could have called it galvanized steel and been just as happy.

Examples:

And...

http://en.wikipedia.org/wiki/Hot-dip_galvanization

Quote - Hot-dip galvanization is a form of galvanization. It is the process of coating iron, steel or aluminium with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 860 °F (460 °C).

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
