If you’ve worked on underground mine or tunnel sites, you know rock faces are never perfectly flat.
Standard flat plates work great on smooth rock surfaces. But when the rock is sloped? The flat plate only touches at one edge. Stress piles up on that single spot. Over time, it can reduce your rock bolt’s load capacity and risk bolt failure.
That’s exactly why we use inclined plates.
The angled plates fit naturally against sloped rock. The whole plate sits flush with the rock face. Load spreads evenly across the plate, instead of focusing on one point.

What this means for your project:
◎ Avoid dangerous stress concentration and point loading
◎ Keep your rock bolt working at its full designed strength
◎ Prevent plate tilt and eccentric tension on bolts
◎ Boost long-term safety and stability of your underground support
We can offer the inclined plates in multiple sizes with different angles for your rock bolt projects.
If you need custom dimensions to match your rock bolt setup, feel free to reach out for technical specs and quotes.
