Our brushed aluminum and standard aluminum signs both use e-panel. The differences between the two are the appearance of the brushed aluminum and the fact that the brushed aluminum is 3mm thick while the standard aluminum signs are 2mm thick. The only other difference of note is the appearance of the color white on the printed sign. We typically do not print white ink on our brushed aluminum unless required by white text or essential white within graphics. In this case spot white ink will be used so as to avoid having white behind your entire design and muting the brushed appearance of the sign.
