R25 anchor bolt is an advanced anchor bolt which can ensure the anchoring effect for complex ground conditions.

R32 anchor bolt is one kind of the R-thread self-drilling anchor bolt. It is composed by hollow anchor bar, anchor nut, anchor plate, anchor coupler, drill bit, centralizer, and the hollow anchor bolt can be cut and lengthened by coupling on request conveniently, which makes high piling output possible.

R38 anchor bolts system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

Sinorock is a professional R51 anchor bolts supplier which has the ISO9000 quality certification and CE certification. It's mainly used in the mineral exploration,tunneling and slope stabilization project.

T30 anchor bolt is suitable for granular soils and fills. This installation method utilizes a Grout Swivel, grout pump and drifter. The technique combines drilling and grouting as a single operation, ensuring that grout is placed over the full length of the borehole.

T40 anchor bolt system is a fully threaded steel bar which can be drilled and grouted into loose or collapsing soils without a casing. The bar features a hollow center for simultaneous drilling and grouting and a rope thread for connection to standard drill tooling.

T52 anchor bolt can be installed into a variety of different soils and ground conditions ranging from sand and gravel to inconsistent fill, boulders, rubble and weathered rock, as well as through footings and base slabs.

T73 anchor bolt have fully threaded rod sections since continuous thread ensures that rods can be cut and coupled at any point. The trapezoidal thread produces an excellent bond between the anchor bolt and grout, and enables connection to conventional drill tooling.

T76 anchor bolt is quick and easy to install through fractured or broken ground. The system is available with a range of harder drill bits for efficient drilling in stronger material.

T103 self drilling anchor bolt is a type of large diameter anchor bolt, which has a larger diameter than other common sizes. It is usually applied to pipe shed and micropile.

T111 anchor bolt is advancing according to easy and similar operation principle under different rock mass and soil conditions. Drilling, anchoring and grouting can be performed in one single operation.

T127 anchor bolt is one of the T-thread self drilling anchor bolt. It is made of seamless steel pipe with thick wall. In addition, surface thread-shaping technology is taken. With a bit at the anchor head, it is easy to cut through various rocks.

T130 anchor bolt is one of the large diameter anchor bolt applied for constructions of shallow buried parts of tunnel portal, sand, gravel, silt, and clays, and in soft to medium fractured rock formations.
