Guide To Specifying Sapphire's Colour Range In order that you receive the finish you desire it is important to specify the finish, colour, coat thickness and alloy grade that the finish is to be applied to. Coating thickness is the most significant indicator of durability for anodised coatings. Often there is no specification for coating thickness just the colour for example “Clear Anodised” and the “cheapest thing” is then often installed (10um), and in a few short years the finish is pitted, stained and eroded. If a thickness of 25um is specified for external use, the coating will last at least four times longer. Remember anodising often represents less than 1% of the project cost, but often represents 100% of the projects appearance. To assist you with this process we have provided you with sample specifications for anodised coatings for interior and exterior use.Sapphire assists with this process through the provision of Colourboard samples labelled with critical information required to identify the correct finish. (refer to ColourBoard Sample Ordering)   Interior Anodising Specification The specified anodising finish shall be Colour - Matt Chocolate Code - M337 Extrusion Alloy - 6060T5 or 6063T5 (Primary billet - no remelt allowed) Sheet Alloy - 5005 (Primary billet - no remelt allowed) Supplier - Sapphire Aluminium       All coatings are to comply with X standard (insert one of the standards listed below) Certificate of compliance to be obtained from Sapphire Aluminium and provided to the architect/designer by the successful tenderer as proof of conformance with the above specification.       Exterior Anodising Specification The specified anodising finish shall be Colour - Matt Chilli - AA25 Code - M6675 Coating Thickness - 25 microns Extrusion Alloy - 6063T5 or 6063T5 (Primary billet - no remelt allowed) Sheet Alloy - 5005 (Primary billet - no remelt allowed) Supplier - Sapphire Aluminium       All coatings are to comply with X standard (insert one of the standards listed below) Certificate of compliance to be obtained from Sapphire Aluminium and provided to the architect/designer by the successful tenderer as proof of conformance with the above specification.       X = One of the following anodising standards that is applicable to your region AS1231-2000 - Australia AAMA 611-98 - Americian Architectural Manufactures Association ASTM B580-79(2000) - ASTM International - USA BS EN 12373-2001 - British & European Standards ISO7599-1983 - International Standard
