Quality Control / Inspection
Strict Quality Control System
Tianjin Guoyu Steel implements quality control throughout the entire production process, from raw material selection to final inspection.Incoming Material Inspection
All cold-rolled and hot-rolled substrates are inspected for chemical composition, mechanical properties, and surface condition before production.Process & Coating Inspection
During galvanizing, zinc coating weight,coating uniformity, and surface quality are continuously monitored to ensure compliance with required standards.Final Inspection & Documentation
Before delivery, each batch is checked for thickness, dimensions, zinc coating, and appearance. Inspection reports and mill test certificates (MTC) can be provided upon request.
