Friction Bolt-33-600mm-manufacture,factory,supplier from China

Friction Bolt -33-600mm FunctionsFriction Bolt -33-600mm is a frictional ground support system.

Friction Bolt-33-1800mm FunctionsFriction Bolt-33-1800mm is a frictional ground support system.

Friction Bolt-33-1500mm FunctionsThe Friction Bolt-33-1500mm operates as a ground support system through frictional forces. When the bolt is inserted into a drilled hole with a smaller diameter, the slot compresses, reducing the bolt's diameter.

Friction Bolt-33-1200mm FunctionsFriction Bolt-33-1200mm is a frictional ground support system.When bolt is inserted into drilling hole with smaller diameter, the slot partially closes and bolt diameter is compressed, which creates radial forces on rock roof surface along the whole length and firmly holds the rock.Friction Bolt-33-1200mm Features&AdvantagesMade from high strength steel band  Independent supporting without plateEasy for installationImmediate frictional Support in axial and radialSimple design,cost savingAvailable in black,cold galvanizing or hot dip galvanizedFric
