After receiving your order, we will start mass production according to your requirements. If you have other diameter, length requirement, please let me know. The raw material is high strength alloy strip steel. Here are Q235, 16Mn, 20Mnsi and other raw materials to choose from. The retaining ring interface has no cracks, no slag inclusions, and no burning through the pipe wall. After the product is assembled, the quality controller will inspect the quality of the product, and the products that pass the inspection will be uniformly labeled.

Our split set rock bolts have many advantages. First, the material is high strength alloy strip steel. The installation is the easiest. There is no anchoring agent required. The friction between the bolt and the rock mass is large. It has high shear and tensile strength. It is also equipped with high-strength pallet. The pallet is evenly stressed.

The split set rock bolt have many applications. The split sets anchor is the most basic part of the roadway support in mining. Reinforce the surrounding rock of the roadway so that the surrounding rock can stabilize. Friction anchors are now used only in mines, but also in strengthening slopes, tunnels and dams.
