Rock Bolts for Tunnel, Mine & Slope Reinforcement — Safe Geotechnical Support Solution

Geotechnical collapse risks are the biggest hidden danger in tunnel construction, underground mining and mountain slope engineering. Rock bolts are the core reinforcement material to stabilize surrounding rock and avoid safety accidents.

Shandong Xinzhongding develops and produces full-series support bolts for all kinds of complex geological conditions:

1. Hollow Grouting Rock Bolt Threaded seamless steel pipe body allows pressure grouting to fill rock cracks, greatly improving surrounding rock integrity. Suitable for broken rock tunnels, subway projects and high steep slopes.
2. Pipe Seam Rock Bolt Elastic open seam structure creates strong extrusion anchoring force after installation, with fast construction speed for underground mine roadway temporary support.
3. Self-drilling Rock Bolt Integrated drill bit design realizes drilling, grouting and anchoring in one step, perfect for loose, easy-collapsible strata and deep foundation pit reinforcement.

All our rock bolts adopt high-strength carbon steel and alloy steel, with anti-rust treatments like galvanization to extend service life in humid underground environments. Each batch will complete tensile strength and load testing before delivery, complying with international tunnel construction standards.

Our rock bolt products have been applied in numerous domestic and overseas infrastructure projects. We can customize bolt length, thread specification and matching pallet & nut accessories according to your geological survey report, offering one-stop ground reinforcement solutions.
