- Industrial enclosures
- Parts receiving later polishing
- Heat-resistant fabrications
Purchase-order checks
- Confirm 2D rather than 2B
- Downstream forming or polishing route
- Critical surface side
- Protection method
- Dimensional and flatness requirements
Protection and acceptance
- State whether the surface is functional or later processed
- Specify critical side and handling protection
- Inspect pickling uniformity, roll marks, scratches and flatness
