Mining Friction Bolt are mainly used in hard rock mines such as copper and gold mines. Bolts are installed in the rock strata by extrusion, which can generate axial and radial frictional expansion force with the rock strata, thereby generating huge supporting force and protecting the safety of the roadway.
Mining Friction Bolt produced by ANTO Company is made of high-yield and high-strength steel; the welding ring has good welding power. In the mine support, even if the rod body is broken, the welding ring is not easy to fall off.
Advantages of Mining Friction bolt:
- Simple installation, saving labor cost.
- Has good yield strength and breaking strength.
- Has good welding ring pull-out force.
- Black or hot dipped galvanized available.
