39mm 47mm Split Set Stabilizer/Friction Rock Bolt/Split Set Rock Bolt Manufacturer in China
Mining Friction Bolts are primarily used in hard rock mines such as copper and gold mines. These bolts are installed in rock strata through extrusion, generating both axial and radial frictional expansion forces that create substantial supporting pressure to maintain roadway safety.
Our Mining Friction Bolts are manufactured from high-yield, high-strength steel with welding rings that maintain excellent welding integrity. Even if the rod body fractures, the welding ring remains securely in place.
