anchor rod
High-quality rock bolts and anchor bolts for underground mining, tunneling, and geotechnical applications. Factory direct from China with ISO 9001 certification.
Stepped Threaded Steel Anchor Bolt
Step-thread steel rock bolt is a steel anchoring component used for mine roadway support, tunnel support, slope reinforcement and underground engineering reinforcement.The product features a threaded or ribbed bar body, which can be matched with accessories including nuts, washers and bearing plates for convenient on-site installation and tightening fixation. Its stepped connection structure improves assembly compatibility and stress stability, making it suitable for engineering projects requiring mass construction, long-term support and supply of customized specifications.
Glass Fiber Reinforced Polymer (GFRP) Bolt
Glass Fiber Reinforced Polymer (GFRP) Bolt, or fiberglass rock bolt, is a non-metallic support component compositely molded from high-strength glass fiber and resin matrix. It is mainly applied in mines, tunnels, underground projects and slope reinforcement. This product is characterized by light weight, corrosion resistance, easy cutting and simple installation. It is especially suitable for environments requiring subsequent excavation, mining or mechanical cutting, such as coal mining faces, tunnel working faces and temporary support zones.To satisfy various construction demands, GFRP bolts are available in solid bars, hollow grouting bars, fully threaded or ribbed structures. Matching accessories including bearing plates, nuts and connectors can be supplied together, enabling more flexible and efficient surrounding rock support solutions for engineering projects
Combo Bolt
Combo Bolt, or combination rock bolt, is a reinforcement product designed for support of mine roadways, tunnels and underground works. It is suitable for construction scenarios that require rapid initial support while maintaining long-term stability of surrounding rock. This bolt delivers immediate support force via mechanical anchoring. Combined with resin or cement-based grout, it achieves sufficient bonding reinforcement to enhance the overall supporting performance in fractured surrounding rock, layered rock mass and high-stress zones.Specifications, lengths, matching bearing plates, nuts, surface treatments and packaging methods are all customizable according to project drawings or on-site working conditions. It is ideal for bulk purchasing by mine engineering contractors, support material purchasers and underground project operators.
Resin Capsule / Cartridge
Resin anchoring agent is a high-performance chemical anchoring material used in geotechnical engineering and structural reinforcement. It is normally used together with anchor bolts or steel bars. Through the rapid reaction and curing of two-component resin, a high-strength bonding mass is formed inside the borehole to achieve a reliable connection between anchor bolts and rock mass or concrete. Featuring fast curing speed, high bonding strength, zero shrinkage and strong corrosion resistance, this product can significantly improve the overall stability of supporting structures. It is widely applied in mine roadways, tunnel projects, slope support, building structure reinforcement and other scenarios, serving as one of the important high-efficiency anchoring solutions in modern engineering.
Self-drilling Hollow Grouting Rock Bolt
Self-drilling hollow grouting anchor bolt is an efficient support product integrating three major functions of drilling, grouting and anchoring, specially designed for geotechnical projects such as tunnels, mines, slopes and foundation pits. Adopting a hollow threaded structure, the interior of the bolt body serves as a grouting channel to realize integrated construction of drilling while grouting, which effectively solves engineering problems including difficult hole forming and insufficient grouting in weak and broken strata.
Expansion Shell Mechanical Rock Bolt
Expansion shell mechanical rock bolts are high-performance active support elements designed for geotechnical engineering. Featuring a mechanical expansion anchor head and high-strength alloy steel body, these bolts deliver immediate anchoring force upon installation without waiting for grout curing. The dual reinforcement mechanism of mechanical locking and grout bonding ensures reliable bearing capacity, while the prestressed design actively controls surrounding rock deformation. Suitable for mines, tunnels, foundation pits, and slope stabilization projects, these bolts excel in complex geological conditions including broken rock, fault zones, and water-rich strata. Available in multiple specifications with customizable options to meet diverse project requirements.
CT Rock Bolt | Special Combination Anchor Bolt for Hard Rock Roadway and Tunnel Support
CT anchor bolt is a special type of anchor bolt commonly used for supporting hard rock roadways, mine tunnels and underground engineering. It is suitable for rock stratum environments that require rapid installation and stable reinforcement. It usually combines mechanical anchoring and grouting reinforcement methods, enabling the quick formation of primary support on construction sites, and subsequent grouting can strengthen the bonding effect between the anchor bolt and surrounding rock. The product can be customized in terms of length, bolt body specifications, bearing plates, anti-corrosion treatment and other configurations according to project requirements, and is applicable to various rock mass reinforcement scenarios such as mining excavation, tunnel driving and underground chambers.
