This Rock Fall protection netting is integrally woven by hot-dip galvanized or zinc-aluminum alloy steel wire, with compact mesh and uniform holes. It is matched with complete supporting components including steel wire ropes, anchor bolts, support ropes and energy dissipating rings. Two material versions (ordinary galvanized & high anti-corrosion zinc-aluminum coating) are optional, featuring strong toughness and outstanding impact resistance. Its flexible structure disperses impact force from falling stones without easy tearing. It fits complex slopes such as steep hills and weathered rock faces, with simple installation. It can block stones of all sizes for long-term use and reduce geological hazards.

Product Advantages
Strong Impact Resistance & Reliable Protection
Adopting high-tensile steel wire mesh matched with energy dissipating ring buffer structure, it bears high-speed impact of large falling rocks and disperses impact load effectively without mesh tearing or collapse. It stably intercepts gravel and dangerous rocks for high-risk slope projects.
01
Weather & Corrosion Resistant for Long Outdoor Service
Steel wire is fully hot-dip galvanized or coated with zinc-aluminum alloy, delivering excellent rust-proof, UV-resistant and anti-corrosion performance. It adapts to outdoor temperature from -35℃ to 70℃, resisting rust and fracture under long-term mountain exposure, cutting maintenance and replacement frequency.
02
Flexible for All Slopes & Easy Installation
Flexible mesh fits uneven mountain surfaces without large-scale mountain excavation. Standard supporting parts like anchor bolts and fasteners enable rapid laying on steep slopes, cliffs and road side slopes, shortening construction period and lowering civil engineering costs.
03
Wide Compatibility for Various Projects
Complying with national slope protection standards, it includes active and passive net series, covering slope protection for highways, railways, mines, scenic spots, water conservancy dams and residential back hills. Standard components support bulk stock and reduce inventory pressure.
04
Eco-Friendly Without Mountain Damage
Light flexible structure avoids large blasting and slope cutting during construction, retaining original mountain vegetation to the maximum extent. Non-toxic coating causes no pollution to soil and water, balancing protection and ecological conservation.
05
Production Technology
All Rock Fall Protection Netting is fully automatically woven by CNC machines. Steel wire undergoes high-temperature galvanizing anti-corrosion treatment before weaving, with reinforced edge locking to prevent wire scattering. Matching steel wire ropes are pre-stretched, energy dissipating rings are integrally stamped, and anchor bolts are cold-drawn and hardened. All finished products pass tensile and salt spray anti-corrosion tests before delivery, with burr-free, unbroken wires and even stress distribution.
Application Scenarios
Transportation Infrastructure: Slopes beside highways & railways, dangerous rock protection at tunnel entrances/exits;
Mining Plants: Slope protection for open-pit mines and waste rock piles;
Scenic Tourism: Dangerous rock treatment for mountain scenic areas, walkways and viewing platforms;
Water Conservancy: Landslide & rock fall prevention for mountains beside reservoirs and river dams;
Residential Supporting: Geological hazard protection for steep slopes behind villages and residential communities.
FAQ
Q: What is the difference between active and passive rock fall fence, and how to choose?
A: Active nets cling tightly to mountain slopes to fix loose dangerous rocks and prevent stones from falling, suitable for weathered and loose rock slopes. Passive nets are built at slope feet as interception barriers to catch fallen rocks, suitable for steep slopes with large height difference and high rock fall risks. You may match them according to mountain height and rock fall volume.
Q: How long will the rock fall protection netting get rusted or damaged outdoors?
A: Nets with zinc-aluminum anti-corrosion coating can serve 8–12 years under normal mountain conditions; ordinary hot-dip galvanized versions work stably for 5–8 years. Its rust and weather resistance is 3 times higher than ordinary black iron wire nets, with rare large-area rust and fracture.
Q: Can the rock fall protection netting be installed closely on steep and uneven mountains? Will it fall off easily?
A: This flexible mesh fits undulating mountain surfaces, fixed by multi-point full-length anchor bolts and horizontal support ropes with locking fasteners. It bears force evenly when hit by falling rocks without local detachment. It can be fully laid on steep slopes, cliffs and uneven rock faces with firm fixation, resisting vibration and impact without loosening.
