Galvanized steel - Page 2

post #21 of 37
I bought a roll of galvanzied aluminum flashing to line the inside lid of my offset to maintain better heat should i go with regular aluminum and return the galvanized?

Yes. You don't want galvanized anywhere near food.

If the heat inside the cooking chamber is less than the melting point of zinc (787F) you'll be fine. The zinc won't vapourize until the temp hits around 1665F. As long as the galvanized metal isn't in direct contact with food, I wouldn't worry about it.

I kept seeing that company advertising their galvanized grates in people's threads. I seen it in like 3-4 threads yesterday. I thought there was one in this thread also

I've never heard of galvanized aluminum. I have heard of anodized aluminum. Are you sure of which you are writing? I think it's more likely that you have galvanized steel or anodized aluminum.

Coated Sheet

GALVALUME® Sheet

U. S. Steel GALVALUME® Steel Sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot-dip process. The nominal coating composition is 55% aluminum and 45% zinc. A small but important addition of silicon is included in the coating alloy. It is added not to enhance the corrosion performance, but to provide good coating adhesion to the steel substrate when the product is roll-formed, drawn, or bent during fabrication.

So that's galvanized steel, correct?

Not exactly..... It's Galvalume..... aluminum and zinc coating...... Galvanized is zinc coated....

But it's not galvanized aluminum. It's steel that has been coated using the process known as galvanization, but with a modified molten liquid. Correct?

I think another term for it is aluminized steel. I read an article the other day about baking pans being what they called aluminized and the process sounded the same as the process in the paragraph he just stated.

I don't know the process.... I think Alumax developed it back in the '70's... I'm sure it was patented but who knows who bought the patents...

The process was described in what you quoted earlier. It's basically hot dip galvanization.

I wouldn't use it for a food contact surface,

How about aluminum beer cans alblancher? lets hope they don't cause Alzheimers or a lot of us will be in trouble.
