The 4-Stage Closed-Loop QC Workflow

Incoming Quality
Raw Steel & HardwareTensile strength tests, wire diameter tolerance (±0.05 mm), and castor hardness checks before entry.

In-Process Check
Bending & Welding LinesFirst-piece sign-off, automated weld penetration checks, and hourly frame alignment audits.

Final Inspection
Coating & PayloadCross-cut adhesion tests, micron thickness verification, and 100% full-capacity load stress checks.

Outgoing Quality
Packaging & LoadingFull knock-down trial assembly, carton burst tests, moisture barrier sealing, and pre-shipment PSI reports.
In-House Testing & Verification Lab
Empirical testing, not visual guesswork. We validate raw strength, surface resilience, and rolling endurance with professional laboratory-grade apparatus.

500-Hour Salt Spray Chamber
Accelerated corrosion resistance testing ensuring chrome, zinc, and epoxy coatings withstand harsh marine shipping and -30°C cold-room environments.

Hydraulic Load & Stress Tester
Static & dynamic overload validation up to 1.5× rated payload, proving 800 lbs per shelf without permanent structural deflection.

Digital Coating Thickness Gauge
Precision micrometer scanning verifying micron-level uniformity (Zinc: ≥10–12µm / Powder: ≥60–80µm) across all welded mesh joints.

Castor Fatigue & Drop Impact Tester
Continuous 10km obstacle-rolling fatigue and drop-impact simulations to eliminate wheel breakdown and brake failure under full dynamic payload.
