Quality Control
Protocol-based inspection and documentation
The UK-ZTO-AN technical control department ensures every product conforms to drawings and standards. We use modern measuring equipment and non-destructive testing methods.
Dimensional Inspection
Precise measurement of all fabricated components against technical drawings using calibrated instruments.
- Length, width, height verification
- Hole positioning & diameter
- Flatness & straightness
- Tolerance compliance
Weld Quality Control
Visual inspection, penetrant testing, and documentation of all welded joints per project specifications.
- Visual weld inspection
- Penetrant testing (PT)
- Weld strength verification
- Welding map compliance
QC Protocols
Every project receives full quality control documentation including measurement protocols, test results, and compliance certificates.
- Dimensional protocols
- Material certificates
- Welding documentation
