T103 Self Drilling Hollow Bar
  • T103 hollow anchor bar is a kind of Sinorock® Self Drilling Anchor Bars. Its friction force is about 2.4 times than wave thread bolt, which adopts structural alloy steel with high yielding strength, so it is immune to hydrogen embrittlement and stress fission.

Function:

1. Basement anchoring of underground projects, anti-floating projects and anti-seismic projects.
2. The management and maintenance of fissure.
3. Convenient transportation and construction, high efficiency for construction progress.

Features:

1. Keep the integrity and stability of surrounding rocks.
2. Control effectively the surrounding rocks of deforming, displacing and cracking.
3. The transportation is convenient, high-efficient.
