Metal Fabrication Drawing Approval Checklist
A fabrication drawing approval checklist covering dimensions, tolerances, material, holes, bends, welds, finish, mounting, and drawing revision.
A fabrication approval needs to make the controlling drawing and the production-critical callouts unmistakable.
What the customer should verify
- Overall and critical dimensions
- Required tolerances
- Material grade and thickness
- Hole locations, sizes and patterns
- Bend directions and radii
- Weld symbols / callouts
- Finish, coating or surface treatment
- Mounting / interface details
- Quantity
- Current drawing revision
Final approval checkpoint
The customer should be approving the exact revision shown. If artwork, copy, dimensions, material, personalization or another production detail changes afterward, create a new revision and collect fresh approval rather than relying on the earlier sign-off.
