Hollow Anchor Rods – Your Reliable Solution for Secure Anchoring

Product Overview
Hollow anchor rods are innovative anchoring solutions designed for rock support, slope stabilization, and underground construction. Featuring a seamless hollow core, these rods enable efficient grouting and cement injection, ensuring superior bonding strength and long-term durability.
Hollow anchor rods Ideal for mining, tunneling, and civil engineering projects, they offer a cost-effective alternative to traditional solid rods while maintaining exceptional load-bearing capacity.
Key Features
- Hollow Core Design: Allows direct grouting through the rod, eliminating the need for external pipes and simplifying installation.
- High-Strength Material: Manufactured from premium steel, with options for corrosion-resistant coatings to suit harsh environments.
- Enhanced Load Capacity: Optimized thread patterns and cross-sectional design distribute stress evenly, reducing failure risks.
- Versatile Applications: Suitable for soft to medium-hard rock formations, soil stabilization, and retaining walls.
- Easy Installation: Lightweight yet robust, reducing labor costs and time on-site.
Technical Specifications
- Material: Alloy steel (ASTM A572 Grade 50 or equivalent).
- Diameter Range: 22mm to 32mm (customizable).
- Length Options: 1.5m to 6m (tailored to project needs).
- Surface Treatment: Hot-dip galvanized or epoxy-coated for corrosion resistance.
- Grouting Compatibility: Works with cement, resin, or chemical grouts.
Why Choose Our Hollow Anchor Rods?
- Efficiency: The hollow design accelerates grouting, cutting installation time by up to 30%.
- Safety: Reduces exposure to hazardous environments by minimizing manual grouting steps.
- Cost-Effective: Lower material and labor costs compared to solid rods, with no compromise on performance.
- Global Standards: Complies with international certifications (ISO, CE, ASTM) for quality assurance.
- Customization: Available in lengths, diameters, and coatings tailored to your project’s geology.
Applications
- Mining: Support for underground tunnels and shafts.
- Civil Engineering: Slope stabilization, bridge foundations, and retaining walls.
- Tunneling: Reinforcement in soft ground or fractured rock zones.
- Disaster Prevention: Landslide mitigation and seismic retrofitting.
Installation Guide
- Drilling: Drill a hole to the required depth and diameter.
- Insertion: Place the hollow rod into the hole, ensuring alignment.
- Grouting: Inject grout through the rod’s core until full saturation.
- Curing: Allow grout to set before applying load (typically 24–48 hours).
- Testing: Conduct pull-out tests to verify bond strength.
Quality Assurance
- Pre-Shipment Inspection: Each batch undergoes rigorous testing for tensile strength, thread integrity, and corrosion resistance.
