Yidao Geotechnical R&D Excellence in Thread Bar Systems
Yidao specializes in R&D, production, and supply of high-strength hot-rolled thread bars and anchoring systems for geotechnical applications. Our product range covers 15mm to 75mm diameters, including nuts, couplers, anchor plates, spacers and rock bolts, manufactured to GB, ASTM, and EN standards.

**Quality Assurance**
Our quality system ensures full traceability from raw materials to final dispatch. We partner with SGS, TUV, CCT and China National Testing Lab for rigorous third-party inspections on mechanical properties, coating integrity, and corrosion resistance, guaranteeing consistent product performance.
**R&D & Innovation**
Our R&D team develops advanced anti-corrosion technologies—hot-dip galvanizing, epoxy coating, and Double Corrosion Protection (DCP) for permanent structures. We also provide custom processing services including cutting, bending, threading, and anchoring system design for complex geotechnical conditions.
**Project Validation**
Our solutions have been deployed in major global projects—slope stabilization in Greece, excavation support in Vietnam, and post-tensioning in Macao bridge engineering—demonstrating proven performance in diverse environments.
