Quality Control for Cold Rolled Carbon Steel Strip SPCC
Tianjin Guoyu Steel enforces stringent quality control across the entire production cycle of cold rolled carbon steel strip SPCC, from raw material sourcing to final delivery.
-
Incoming Material Inspection All raw coil substrates are tested for chemical composition, mechanical properties and surface condition; non-conforming materials are rejected outright to lay a solid foundation for high-quality SPCC strip production.
-
In-Process Inspection Key cold rolling parameters (thickness consistency, flatness, width tolerance, surface smoothness) are continuously monitored, with real-time adjustments to ensure compliance with SPCC product standards and customer specs.
-
Final Inspection & Documentation Each batch undergoes a comprehensive check of dimensions, surface finish and formability before shipment. Mill Test Certificates (MTC) and detailed inspection reports are available on request.
