If you take some hot rolled steel - or stainless for that much -
and put it in the kitchen oven at 350 degrees F. Wait for a couple of hours
or have the oven at that temp and wait 30 minutes - it will be golden.

The colors are based on the temperature.

We are doing a survey on some incredible custom homes. I will take some
pictures and post them at flickr next week.

These gates are one of a kind custom, and all appear to be made of steel.
But they use flat panels of 26ga. or so that have lots of hues in them.
Some appear that they have been discolored by heat, going to a purplish
tint. Some look golden, but more like light copper than actual gold. They
are all shiny on the surface, indicating clear coating. They are all sorts
of designs from suns to Indian symbols to abstracts. They are a combination
of tubular frame and flat panel inserts.

I was wondering if anyone knows how they get the colors in/on the metal.

I have to go to the manufacturing company next week to get the replacement
costs, and that should be interesting, as I will be looking for as much as
they will divulge about the process.

Nice looking stuff, and like I say, I'll have some pictures next week.
