Anodized Aluminum & ATAS Products

April 2, 2021
What is Coil Anodizing? Electrochemical process where the anodic layer from base aluminum is grown through a series of tanks.


  • Anodizing forms a protective oxide layer that is hard.
  • Protects the metal from corrosion and abrasion over the long term.
  • Self-healing if damaged, as the aluminum will naturally create a protective oxide layer wherever it is exposed to the elements.
  • Unlike paints or coatings, this oxide layer is grown from the raw aluminum and bonded at the molecular level so it cannot chip, flake or peel.


  • Varied color options.
  • Finish permanent.
  • Cost efficient solution to the natural metal trend such as zinc.

Color and Appearance

  • Continuous coil-anodizing process can achieve excellent color consistency, even across multiple coils or production runs.
  • Consistency is possible because the continuous coil anodizing process exposes every square inch of the coil to each part of the process for the same amount of time.
  • Anodized aluminum can be made to look like almost any other metal, including brass, copper, bronze, zinc, gold, silver, stainless steel, titanium and carbon steel. Anodized aluminum, however, does not tarnish like brass, patina like copper or fade like bronze, so these metal looks are stable over time and with UV exposure.


  • The handling and installation of coil-anodized aluminum are simple, as the material is lightweight and workable. Can be installed on buildings with standard hand tools.

Cleaning and Maintenance

  • Because anodizing is so hard, you want to use an abrasive cleaning sponge with a mild dish washing soap. Do not use harsh acidic or alkaline cleaners because they may destroy the finish. Use solvents with care as they may stain the finish. It is best to try a test area first.
