Mill finish refers to the raw, unprocessed surface appearance of metal products as they come directly from the manufacturing mill. It's the most basic and economical surface finish for metals like aluminum or steel. When you see this term in resumes or job descriptions, it means the metal hasn't been painted, polished, or given any special treatment after the manufacturing process. Think of it like unfinished wood - it's the material in its natural state right after production. This finish type is common in industrial applications where appearance isn't the main priority, or when the metal will be further processed later.
