Expansion Shell Anchor-Custom Expansion Shell Anchors | Pre-Stress Roof & Ground Support Bolts
Our high-quality expansion shell anchors are designed for mining, tunneling, underground construction, and geotechnical reinforcement applications. With fast mechanical expansion and immediate anchoring force, they provide reliable load-bearing performance in rock support, slope stabilization, and excavation reinforcement projects. Available in custom sizes, materials, thread types, and pre-stress designs, these anchors can be tailored to different ground conditions and engineering requirements. Their robust structure helps ensure stable installation, strong holding capacity, and long-term performance in demanding environments. Easy to install and suitable for rapid on-site deployment, expansion shell anchors are an efficient solution for projects requiring dependable reinforcement and immediate support.
Precision Rolled Threaded Steel Anchor Bar
Fine-rolled threaded steel anchor bolt is a high-strength steel bar product used for engineering anchoring, supporting reinforcement and prestressed connection. It has continuous threads on its surface and can be matched with nuts, bearing plates, connectors and other accessories. This product is widely applied in engineering scenarios such as tunnels, mines, slopes, foundation pits, bridges, water conservancy projects and concrete structure reinforcement. It features convenient connection, reliable anchoring and strong construction adaptability. Common specifications include 15mm, 16mm, 18mm, 20mm, 22mm, 25mm, 32mm, 36mm and 40mm. Optional strength grades are PSB830, PSB930 and PSB1080. Custom length cutting and bulk supply are available in accordance with project requirements.
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.
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.
