Century Rock Fall Netting

An Introduction To Rock Fall Netting

Rock fall netting is a type of passive protection system used in geotechnical engineering to mitigate the risk of rockfall hazards. It consists of steel wire mesh or cable nets that are anchored to the slope or cliff face to prevent falling rocks from reaching the ground below. The netting is designed to mitigate the risk of falling rocks and prevent damage or injury to people and infrastructure.

Rock fall netting is typically used in areas where there is a risk of rockfall, such as highways, railways, mining operations, and urban areas located near steep slopes or cliffs. It is a cost-effective and practical solution for protecting people and property from the hazards of rockfall.

The design and installation of rockfall netting require a thorough understanding of the geological conditions and the potential hazards in the area. Proper installation and maintenance of the netting are crucial to ensure its effectiveness over time. Rock fall netting has proven to be an effective method for mitigating rockfall hazards and has saved lives and prevented property damage in many situations.

Anti-Corrosion Coating + PVC

Century Rock Fall Netting is manufactured to the highest standards through our global partner Bekaert Wire, the world largest wire producer with over 200 years experience in the wire and wire coating industry.

To achieve best possible active corrosion resistance Bekaert offers Bezinal®, a proprietary range of zinc aluminum coatings. Bezinal® offers the best performance in terms of corrosion and heat resistance, durability and processability thus extensive life cycle can be expected when choosing Century Rock Fall Netting and Century Gabions.

Bezinal® 2000: 90% Zn/10% Al – Superior protection in high corrosion environments.

Bezinal® coated wires resist corrosion 2 to 6 times longer in heavily polluting corrosion tests than hot-dip galvanized wires and last up to 8 times longer in heavily polluted areas. This is thanks to the formation of the dense and high quality passivation layer that is mainly formed by aluminum oxides.

+ PVC Bonded Layer

In order to increase lifecycle even further of Century Rock Fall Netting we opt for the addition of PVC thermally bonded layer. This technology combines the excellent adhesive properties of fusion bonded coatings with the surface quality of extruded wires; this results in an aesthetically pleasing and crack resistant coating with good dimensional tolerances. Thanks to these features, this fusion-bonded wire is ideal for use in environments, such as areas exposed to extreme temperatures, highly corrosive atmospheres, and/or abrasive elements. The increased lifecycle of the wire is extensive in comparison to the small increase in cost.


  1. Road Safety: Rock Fall Netting is indispensable for roadways in hilly or mountainous regions where rockslides or falling rocks are a constant risk. It provides a protective barrier to prevent rocks from landing on highways, thus ensuring the safety of commuters.
  2. Railway Protection: For railways traversing rocky terrain, rock netting serves as an essential safeguard. It prevents rocks or debris from obstructing rail lines, reducing the risk of accidents and service interruptions.
  3. Bridges and Tunnels: Bridges and tunnels are vulnerable points where falling rocks can wreak havoc. Installing Rock Netting around these structures ensures uninterrupted transport flow and minimizes costly structural damage.
  4. Property Protection: Beyond infrastructure, rock netting shields homes, businesses, and other properties in rock-prone areas. It provides peace of mind by reducing the threat of property damage and personal injury.


  1. Enhanced Safety: Rock netting is a proactive safety measure that significantly reduces the risk of accidents caused by falling rocks or debris. This results in fewer injuries, fatalities, and property damage.
  2. Continuous Infrastructure Operation: By preventing blockages and damage to roads, railways, bridges, and tunnels, the netting ensures uninterrupted transportation services, minimizing downtime and associated economic losses.
  3. Cost Savings: Investing in Rock Fall Netting is a cost-effective way to avoid expensive repairs and reconstruction caused by rockslides. It also reduces the need for emergency response and maintenance.
  4. Property Value Preservation: Property owners benefit from increased property values and insurance savings, knowing that their assets are protected from potential rockfall damage.
  5. Environmental Responsibility: Rock Fall Netting is environmentally friendly and minimizes the need for destructive methods like rock blasting, which can harm the surrounding ecosystem.

In conclusion, Century Rock Fall Netting is a smart investment that offers both safety and financial advantages. It ensures the protection of critical infrastructure and properties while reducing the risks and costs associated with rockfall incidents. It’s a win-win solution for safety-conscious organizations and government agencies alike.
