Key Features
- Commonly used when surface support is required in environments with ongoing deformation or seismically active.
- The longitudinal wire strand is able to slip under load conditions through the cross wires to distribute load over several bolts.
- OSRO straps provide a large surface confinement to loose rock that can form between bolts.
- Weld specification AS/NZ4680.
- Corrosion protection can be provided by hot dip galvanising.
