Quality Control
Strict Quality Control System
Tianjin Guoyu Steel implements stringent quality control throughout the entire production process of steel wire rods , from raw material selection to final inspection, fully aligned with the quality inspection characteristics of coiled bars.
Incoming Material Inspection
All steel wire rods are inspected for chemical composition, mechanical properties, and surface conditions (free of cracks, folds, and inclusions) before production. Non-conforming billets are rejected to ensure the stability of subsequent processes.
Process Inspection
During heating, rolling, water cooling, and coiling, key parameters such as diameter tolerance, dimensional uniformity, surface smoothness, and mechanical property consistency are monitored in real time. The production line is adjusted promptly to meet standard and customer requirements.
Final Inspection & Documentation
Before delivery, each batch of coiled bars undergoes a comprehensive check covering diameter deviation, coil weight, surface defects, and mechanical performance. Detailed inspection reports and Mill Test Certificates (MTC) are available upon customer request.
