Basic Information

SupAnchor has achieved the security application of 39,000,000 meters self-drilling anchor bar in the world.

The Self-Drilling Anchor System enables drilling and grouting in one operation.

The loadbearing member is a ribbed hollow steel bar that serves as a sacrificial drilling rod, an injection tube and a reinforcing bar (the 3-in-1 principle).

R thread is designed and produced according to ISO 10208 and ISO 1720 standards, and can be quickly connected and installed in the field.

Basic Information

SupAnchor is the No.1 manufacturer and exporter of self-drilling anchors in Asia.

T thread is designed and produced according to T International Standard, and can be quickly connected and installed in the field. The hollow bar incorporates a left-hand or right-hand thread for standard rotary percussive drilling.

The relative rib area fR serves as a parameter for the quality of the bond and lies close to the optimum value of fR = 0.21 - fR = 0.33.

In addition to the good bond, the rib surfaces at an angle of 45° reduce the splitting forces. The crack widths at maximum load lie below the 0.1 mm.

Options of Anti-corrosion
  • * Hot-dip galvanizing
  • * SupCoating (HDG + Epoxy)
  • * Stainless steel

Basic Information

TROPE Drilling Hollow bar is SupAnchor’s first and patented TR thread in the world,the loadbearing member is a ribbed hollow steel bar that serves as a sacrificial drilling rod, an injection tube and a reinforcing bar (the 3-in-1 principle).

TR Self-Drilling Hollow Bar is designed and produced according to ASTM A615.

45˚ angle T thread design makes the effective area of thread larger and achieves the better bond to concrete and makes the crack widths at maximum load lie below 0.1 mm, which could be connected perfectly to ROPE thread , like R32, R38 and R51 (to ISO 10208 and ISO 1720) at job site.

Options of Anti-corrosion
  • * Hot-dip galvanizing
  • * SupCoating (HDG + Epoxy)
  • * Stainless steel
