Galvanized Thread Bar Rock Bolt

The anchor is not only used in mines, but also used in engineering technology to strengthen the main body of slopes, tunnels and dams. Anchor bolts (also known as soil anchors and soil nails) are formed by drilling holes in the side walls of natural soil layers, placing tension members, and grouting anchors. The tension rods can be divided into coarse steel bars, high-strength steel wire bundles, steel strands, etc. according to the materials used.
