Why Can We Always Ensure Excellent Quality

Quality Control

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
