For decades, mining, tunneling, and slope projects have been plagued by slow curing cycles, spiraling drilling costs, poor geological adaptability, and premature corrosion—bottlenecks that compromise both schedules and safety. Yidao high-strength threaded bar rock bolts overcome these obstacles with a purpose-built dual-series system: fully grouted SN anchors and expansion shell bolts, delivering targeted reinforcement across all ground conditions.
Industry Pain Points vs. Yidao Advantages as below:
Pain Point | Conventional Limitations | Yidao Advantages |
Slow construction | Grouted bolts require long curing before load-bearing, delaying progress. | Expansion shell bolts offer instant load capacity post-installation; grouted types support post-grouting for enhanced long-term anchorage. |
High drilling costs | Larger boreholes are needed for adequate anchoring force, raising expenses. | High-tensile threaded steel delivers strong anchorage with smaller bore sizes, cutting drilling budgets significantly. |
Limited Geological Adaptability | Single-type bolts fail across soft soil, hard rock, or corrosive strata. | Dual-series flexibility covers soil stabilization, medium-hard rock, and salt-mine projects with ease. |
Short anti-corrosion life | Uncoated bolts rust quickly in damp or aggressive environments. | Hot-dip galvanized,DCP options for both series ensure durable, long-term rust protection. |
Complex drilling angles | Standard bolts cannot adapt to irregular borehole trajectories, causing rework. | Optimized angle compensation fits complex site conditions flawlessly, minimizing on-site adjustments. |
**Engineered for Performance, Supported by Reliability**
With high tensile strength, Yidao Thread bar Rock Bolts have full ranges diameters and steel grade , to achieve an ideal balance of installation efficiency, cost control, and long-term durability.
Whether stabilizing steep slopes, reinforcing deep mine tunnels, or securing specialized salt-mine excavations, our dual-series system provides versatile, dependable, and economically viable anchoring technology—enabling projects to advance with confidence.
