    Which is rolled to a thickness of 0.005” (above 0.005” it is technically considered to be sheet) and is used mainly for thermal insulation and vapor barriers. It may serve also as a surface finish material when laminated to various sheet and board materials. In this form it also suppliesadditional insulation value to the sheet or board.

  • 12. 
    Aluminum finishes that are based on chemical reactions withthe aluminum surface to achieve one of the following results: (a)Floor Panel Wall PanelOrnamental AluminumAluminum Mesh andWire ClothPig Ironetching, cleaning, or polishing of the surface to remove any oxide filmor surface irregularity and provide a design, a clean surface texture, ora polished effect; and (b) oxidizing of the surface with aluminum orother metallic oxides that protect the surface or serve as a base forsubsequent treatment, or both. Chemical finishes permit only limitedcolors that are not as satisfying as the color films obtained onelectrolytically-applied (anodized) oxide films

    • D. 

      Electroplating

  • 13. 
    Commonly referred to as anodized finishes, thesefinishes are based on the specific ability of aluminum to develop aprotective coating of oxide on its surface. The coating formed may betransparent or opaque. It is hard, yet when colored finishes are desired,it is porous enough to absorb dyes until the final treatment which sealsthe surface. Of the colors used in anodic treatments, architectural,architectural gold has proven to be one of the most stable from thestandpoint of fade resistance. Others are blue and, more recently,brown and black
