• MIG welding for high-volume production with uniform quality
• Skilled welders ensure repeatable weld penetration and clean bead appearance

Inspection & Verification:

• Dimensional checks using precision jigs and CMM
• Visual, penetrant, and destructive testing as needed
• Batch traceability and documentation

Surface Finishing:

• Grinding, polishing, and bead blasting
• Powder coating, anodizing, or custom finishes
• Ready-for-assembly output

Packaging & Logistics:

• Secure export packaging
• Batch labeling and full traceability
• Global shipping support

Our structured workflow guarantees bicycle head tube assemblies that meet strict functional and aesthetic standards for OEMs and custom frame builders.
