Product Detailed
1. Mining underground rock bolt 2. Diameter:16-25mm 3. MG500, MG450, MG335 thread bar are optional. 4. High tensile strength

Mining underground rock bolt  left hand and right hand are all available, specifications range from 16mm to 25mm. MG500, MG450, MG335 thread bar are optional. The tensile strength, yield strength and elongation could reach a high standard. Thread bar has been used widely in tunnel, mining, roof supporting of underground works.

Product Features:

1 The Bar has closely defined mechanical properties which provide consistent performance under long term anchor loading

2 The high ductility and smooth, relatively flat rate of strain hardening ensures a high margin of safety against tensile/shear overload in the case of transverse movements in the rock soil.

3 The rigidity of the anchors makes them easy to install especially in overhead applications

4 High shear bond as deformations are designed for shear interlock with concrete or resin.

5 Transmits the anchor forces efficiently to the grout body without additional fittings

6 Standard stock lengths may be stored and cut to suit the application
