3 in 1 concept : drilling rod, anchor bar & grouting pipe.
Suitable for both permanent and temporary applications.
Optimum bonding and load transfer
Complete solution including plate and bolts.
Splicing system to adjust to custom lengths.
Standard sacrificial drill bits for every ground conditions.
Benefits
Flexible installation : core injection to suit all ground conditions.
Safely : Visual control of full encapsulation.
One step installation with sacrificial drill bits. drilling, placing ,grouting.
No cased borehole allowing ground preservation.
Corrosion Protection
For temporary applications the corrosion protection is achieved through encapsulation with grout.
For permanent applications, SRONS Hollow Rock Bolts can be hot dip galvanized according to EN-1461, epoxy coated or supplied with a sacrificial thickness if accounted for all design stage.

Available with either leh hand or right hand threads
High grade steel effectively reduces the diameter of the bar allowing for easier handling and a smaller bore hole.
Continuous thread makes connections, possible at any point and increases bonding.
Coarse thread and surface hardening allow for rough handling.
