2.Fast drilling and installation, because drilling, installation and grouting are in a single operation.

3.Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bond with the borehole gout.

drilling.

5.Continuous threads ensure the bars can be cut and coupled at any point, or extended.

6.Different anchor bits are available for different ground conditions.

7.Duplex anti-crossion prosess ,hot-dip galvanized and epoxy coating system.
