Incoming Material and Component Control
At Yidao, quality begins at the source. Every raw material and component—from steel bar materials to nuts, couplers, and anchor plates—must pass our stringent verification before entering production. Our ISO 9001-certified control system ensures full traceability, consistent quality, and reliable performance in every finished product.
Incoming Material Inspection & Traceability
Every steel delivery arrives with clear tags and material certificates, specifying grade, heat number, and dimensions. Upon receipt, our quality team inspects surface condition, dimensional accuracy, and mechanical properties—with all results documented. Only fully verified materials are approved for production, and this traceability extends to final dispatch, where every finished product carries identifiable batch information for complete visibility.

Systematic Storage and FIFO Management
All approved materials are stored in clearly designated areas, organized by type, specification, and batch. Our warehouse follows a strict **First-In, First-Out (FIFO)** principle to ensure proper rotation and prevent aging. Each shipment is accompanied by detailed delivery documentation, enabling accurate tracking and inventory control at every stage.
