As an experienced ISO self drilling rock bolt manufacturer, Sinorock supplies one of the largest selections of precision manufactured self drilling rock bolts offered in a wide variety of sizes in both inch and alternative sizes. We are a progressive, problem-solving self drilling rock bolt manufacturer, working in long-term partnership with our customers to realise your project’s full aesthetic and functional potential.

The Sinorock self drilling rock bolt employs the fully threaded Hollow Bar. The Hollow Bar is cold rolled to form standard rope thread. The rolling process refines the grain structure of the steel, increasing the yield strength and producing a robust hollow bar acting as both drill rod and grouting tube during installation. The formed standard rope thread allows the length of the Hollow Bar to be extended by couplers, giving the Sinorock self drilling anchor bolt more flexible in transportation and installation than the regular rock bolts.

In diverse ground conditions, from gravel, sand, or clay, or on sites with insufficient structural integrity, the Minova SDA self-drilling bars as micropiles are versatile in their application, quick and reliable in their installation, and compatible with conventional drilling equipment. Once installed, they are an effective means of preventing settlement and helping to increase soil stability.
