Rock bolts, the latest underpinning products, to improve your project's efficiency. Our rock bolts are made from micro alloy steel tubing.
They are perfect for soil nails, tie down and tie back anchors, and micropiles. Rock bolts can be used for all types of soil including decomposed rocks, clay soils, loose sand, and round gravel. Rock bolts have geotechnical features that makes this product ultimately efficient and effective. These anchors come in different sizes to meet loading requirements for every project.
The self drilling rock bolt in Sinorock can be well connected with drilling machine, rock bolting jumbo, grouting machine, etc.The hollow anchor bar is a drill pipe which is convenient and time-saving, it can transmit structural load to foundation and then limit the deformation of buildings. Because of it with standard full thread, it can be cut and lengthened according to clients’ specific demands.
The anchor bar can be connected by couplings and it is suitable in narrow work spaces. Clients can choose different drill bits for different ground conditions. Based on the different specifications of anchor bar, the technical parameters is different, and the ultimate load, yield load is different, too. Owing to the conventional standards of self drilling anchor bar: R-thread (25/32/38/51mm) and T-thread (30/40/52/73/76/103/111/127mm), it provides higher bonding stress than smooth steel pipe.
