Guide to 2-Step Anodizing vs. Integral Color (Discontinued)

Because of certain performance advantages, SAF now offers the more generally accepted 2-step anodizing process. We no longer offer the Integral Color, aka Duranodic, anodizing process.

Below are some key differences between the two anodizing processes, especially for architectural aluminum finishing applications:

2-Step anodizing

  • Does not craze when fabricated as badly as Integral
  • Color is independent of coating thickness
  • In general, more anodizers use the 2-step process

Integral Color (Duranodic) DISCONTINUED

  • Harder coat (more dense) than 2-step
  • Generally a thicker coat than 2-step unless Class I 2-step is specified
  • Single step process
  • Hides welds a little better than 2-step
