Split Set Rock Bolt is a friction type split sleeve anchor designed specifically for underground engineering, manufactured by ChangQi using high-strength steel material. Through a unique slotted steel pipe structure and welded ring flange design, it achieves fast installation and stable support. Its core function is to transfer loads through friction between the pipe body and the borehole wall, suitable for rock reinforcement scenarios under various complex geological conditions, such as mining tunnels, tunnel excavation, reservoir dams, and slope protection.

Hydraulic expansion anchor rod is an innovative anchoring system designed specifically for mine support. It is made of seamless steel pipes, with an outer diameter larger than the drilling diameter, and achieves high-strength anchoring through the principle of hydraulic expansion. Its core advantages lie in its immediate bearing capacity, high anchoring force, and ability to adapt to complex geological conditions, especially suitable for fractured strata and prone to collapse areas in mining. It effectively solves the problem of insufficient anchoring force of traditional anchor rods in weak surrounding rocks and is a key support tool for mine safety production.

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.

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.
