Steel Ring Net - Passive Rockfall Protection Barrier System
The Steel Ring Net system are one form of a passive protection structure. and sometimes it is also used to active rockfall drapery mesh. HESLY Steel Ring Net have the highest strength of any mesh in the range. Steel Ring Nets are ideal for situations where there is a combination of highly undulating slope face, large boulders and a high risk of dynamic impacts.
What Can The Hesly Steel Ring Nets Be Used For ?
The Hesly Steel Ring Nets are also used on rock slopes in simple drapery applications with large rock masses prone to failure; Ring Nets with their high deformability characteristics can absorb impact load rupture. This high impact absorption characteristic is utililised in the rockfall catch fence application with a high energy level, typically >750kJ. There are different ring nets (either 4C or 6C) depending on the required tensile strength or absorption capacity.

Advantages of Steel Ring Nets
- Ring Nets allows high mechanical durability
- Multi-directional strength/strain performance
- Excellent dynamic impact resistance
- High durability and safety during maintenance operations
- Variety of coatings to balance commercial and performance requirements
- No overlapping mesh on lateral connections means fast installation and minimal waste
- Variety of lengths and widths available reducing installation time and waste
How to Install The Ring Nets Panels
The Steel Ring nets usually arrive on site folded into bundles on a pallet in their required dimension - e.g. 4m x 10m. The ring net bundles must be laid out on a flat ground into their respective dimensions. The adjacent panels are connected with shackles at every ring location without overlapping. A specialist abseiling contractor is required for this operation.
