Identify the material and condition
State the aluminum alloy and condition from the drawing or material specification. If the material is not fixed, identify the properties that matter and request confirmation before selecting an alternative. Material and surface treatment should be reviewed together.
Describe the required color
Provide a recognized color reference, approved sample, or written visual criteria. Explain which surfaces are cosmetic and how visible variation will be evaluated. Do not rely on a color name alone when appearance consistency is important.
Mark areas that must remain untreated
Show masked surfaces, electrical contacts, threads, mating faces, and critical fits on the drawing. State where dimensional or functional acceptance matters after finishing and ask the supplier to confirm how those areas are handled.
Set inspection and sample expectations
Define appearance acceptance, required dimensional checks, and any sample approval or inspection record. Identify quantity, revision, packaging, and delivery assumptions so the quote covers the same scope.
Compare finish quotes by detail
Confirm the material, color reference, masking, inspection, included operations, exclusions, and acceptance criteria before comparing price or timing. If the finish is applied by a separate supplier, identify who owns final approval and records.
