Friction Rock Bolt
Product Details
Our Friction Stabilizer completed with dome plate has very high strength split tube with welded ring, which guarantees for very good & typical Lab Pull Test.
The Drilling Hole for Friction Stabilizer should be cleaned and examined to ensure the friction bolt will insert smoothly. Variation in hole daimeters(due to differing strentths of rock strata or excessively gragmented ground) can yield variations in anchorage capacities at various elevations.
For Friction Stabilizer, it is good for immediate ground support, but not suitable for very soft rock stratas, thus permanent support and roof support is also not recommended.
Norminal Sizes are 33mm, 39mm and 46mm. We can also make special Bolt sizes like 47mm etc.
Friction Rock Bolt(galvanized or black) is mainly used as a good ground support products in coal mines, copper mines, subways and tunnels etc.
