Since its inception in 2011, Sinorock has continued to invent, manufacture, and sell only Sinorock® BRAND Anchors, the highest quality, and best-performing self-drilling hollow anchor bar on the market. All are designed to solve real problems on the job site, and, at home.
The Self-drilling hollow anchor bar is comprised of a hollow threaded bar with an attached drill bit that performs drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension. The Self drilling anchor bolts are known for their excellent load capacity and are available in Normal (N) and Special (S) types with diameters from 1 to 4 in. (25 to 103 mm).
As the leading anchor bolt manufacturer, we are committed to advancing China industry while minimizing our impact on the environment. We’re proud of our history and commitment to delivering quality products and service, and invite you to learn why we are passionate about what we do and about the little details that drive us every day.
