7-STAGE QUALITY CONTROL

Every product passes through our rigorous QC pipeline

01
Steel Inspection
Material grade verification, thickness measurement, hardness testing on every steel batch.
02
Weld Quality
X-ray sampling of robotic welds. Visual + magnetic particle inspection on manual joints.
03
Surface Finish
Adhesion test, thickness gauge, salt spray corrosion test on powder-coated surfaces.
04
Assembly Check
Bolt torque verification, bearing alignment, cable tension calibration on assembled units.
05
Load Testing
Static load test at 150% rated capacity. Dynamic motion cycle test at 100,000 repetitions.
06
Safety Verification
