Self drilling anchor bolts are suitable for a variety of complex geological conditions including gravel, rock, sand, and ground. It adopts the way of drilling, grouting and anchoring work at the same time, which not only saves time, but also solves the shortcomings of the traditional anchoring method, which is easy to collapse after drilling. The self drilling bolt itself has good tensile and anti-bending forces. Under the action of the grouting material, a stable support is formed between the anchor rod and the supporting geology. Sinorock® has performed anti-corrosion protection for self drilling bolts to ensure the durability of the bolts and provide long-term support for the project. We have advanced bolt production lines, accessories processing equipment and testing equipment to provide customers with high quality self drilling anchors. The emergence of self drilling bolts is a major innovation in the anchoring method of the construction industry. It has applications in various projects such as tunnel advance support, hydraulic engineering project and coal mine roadway.
