How much does a custom surface finish cost?
It depends on the process, the roughness target, sheet size, quantity and current alloy prices, so there is no single price per square metre. Among standard finishes, mirror and PVD sit at the top of the cost ladder because both add processing passes to the same sheet.
The real cost drivers
Number of processing passes, yield loss on the sheet, order quantity, sheet size and whether the pattern needs dedicated tooling. Tooling is a one-time charge per pattern and is never repeated per batch.
Where savings are genuine
One finish family across a project, standard sheet sizes, and consolidated batches rather than repeated small releases. These reduce handling and set-up more than any negotiation on unit price.
What to send for a quote
Finish and process, base grade, thickness, sheet size, quantity, packing requirement and destination port. Missing any one of them turns a quotation into a range.
