Quality Assurance: Traceable, Reliable, Engineering-Grade
Safety and durability are non-negotiable in prestressed concrete structures. At Yihang, we enforce a full-process quality control system from raw material to final shipment:
- Incoming material inspection with mill test reports and spectral analysis
- In-process controls: heat treatment monitoring, hardness profiling
- Batch traceability & comprehensive documentation: material certificates, hardness reports, dimensional inspection records included with every shipment
- Strict adherence to “Inspect at Every Stage, First-In-First-Out (FIFO), Ship Only After Final QA" protocols
