Special notes

Lighting and computer monitors may change the way custom colored metals look. You can always request a color chart to make sure you're getting the right color metal.
Different suppliers may call different colored metals by the same name. Please, let us know the correct color code when placing an order.
Not all metals may be available at all times, but we can most likely order what you need.
Different colors and gauges / thicknesses may also be available. Please take a look at the gauge and weight chart page or contact us for more information.
If the metal needed is not listed here, please contact us as we may be able to place an special order for you.
