Our Process

Quality Control Process

🔩

Raw Material Inspection

All incoming raw materials are tested for chemical composition, tensile strength, and dimensional accuracy before production.

⚙️

In-Process Quality Check

Each manufacturing stage is monitored with precision instruments to ensure dimensional tolerances are maintained.

🎯

Go / No-Go Gauge Test

Thread accuracy is verified using calibrated Go/No-Go gauges to ensure proper coupler fitment and connection reliability.

💪

Tensile Strength Test

Products are tested for ultimate tensile strength to confirm performance meets or exceeds parent rebar specifications.

📋

Final Inspection

Every finished product undergoes a final dimensional and visual inspection before dispatch to ensure zero-defect delivery.
