How to Specify |
How to Specify Finishes on AluminumIdentify & Furnish the Finish You NeedThe Aluminum Association has developed a system of designation for finishes on aluminum to assure that your suppliers can identify and furnish the finish you specify. Specific finishes of the various types are designated by a letter followed by a two-digit numeral. Each designation may be combined into a single composite designation to identify a sequence of operations covering all of the important steps leading to a final complex finish. Almost all finishes used on aluminum may be subdivided into three major categories: mechanical finishes, chemical finishes, coatings. Descriptions of the most commonly utilized finishes are as follows: Mechanical: (M) Chemical (C) Anodic Coatings (A) All designations are appropriate for non-architectural applications as well. Composite designation examples: All composite designations are preceded by the letters AA to identify them as an Aluminum Association designation. Example 1: Aluminum Association (plus) Mechanical Finish (plus) Chemical Cleaning (plus) Chemical Etching (plus) Anodic Coating translates to: an Architectural Class II clear matte anodized finish designated as: AA-M10 C12 C22 A31. Example 2: An Architectural Class I textured medium bronze electrolytic deposition (2-step) would be designated: AA-M32 C12 C22 A44. Example 3: An Architectural Class I diffused brite electrolytic deposition and overdye (3-step) would be designated: AA-M10 C12 C32 A44/43. Find out more about anodizing...
