This rockfall fence is produced with two types of anti-corrosion steel wire: hot-dip galvanized wire and zinc-aluminum alloy wire. It is equipped with a full set of standard accessories including support steel cables, buffer energy dissipation rings, fixed anchor bolts and fastening buckles. The mesh sheets are neatly arranged with unified aperture sizes. Its flexible deformation can disperse the impact force generated by rock collision. It is suitable for complex terrains such as weathered rock slopes, uneven cliff faces and waste rock accumulation slopes. No large-scale mountain excavation is required during construction, and it can block stones of all sizes for a long time, greatly reducing the occurrence risks of mountain landslides and rockfall disasters.

Product Services
Customized Matching Service
We can adjust wire thickness, anchor length and overall protection energy according to mountain drop height, rockfall volume and local climate. Custom supporting accessories are developed for special working conditions such as high altitude, severe cold and high-corrosion mining areas to meet construction demands of different projects.
01
Full-process Technical Guidance Service
Professional technicians provide site survey and scheme design support. During construction, online and offline guidance covering anchor layout, mesh splicing and energy ring installation is available to resolve slope construction difficulties and avoid construction errors.
02
Fast Delivery Service
All series components are mass-produced in standardized mode. Conventional specifications are sufficiently stocked for same-day shipment of small orders. Exclusive production schedules are formulated for large engineering orders to ensure construction progress is not delayed.
03
Post-sale Inspection & Maintenance Service
Regular return visits and inspections are provided after delivery. Targeted maintenance plans are offered for loose mesh and rusted accessories. Replacement steel cables, buckles and anchor bolts are supplied to cut long-term maintenance costs.
04
One-stop Supporting Service
Apart from main rockfall fence, complete matching grids, support ropes and anchoring consumables are provided together. Customers do not need to purchase from multiple suppliers; all goods are packed and shipped uniformly to simplify procurement procedures and save time and logistics expenses.

Application Scenarios
Traffic Engineering: Slopes along expressways, national highways and railways, rock interception protection at tunnel entrances and bridge head steep slopes;
Open-pit Mine Projects: Rockfall prevention for mining working faces and waste rock stacking mountains & mine spoil heaps;
Mountain Tourism Projects: Dangerous rock treatment works for hiking trails and viewing platforms;
Water Conservancy Disaster Prevention Works: Mountain slopes beside reservoirs and rivers, preventing landslides and gravel impact on dams;
Urban & Rural Disaster Prevention: Geological hazard protection for steep slopes behind villages, suburban residential areas and ring mountain roads.
FAQ
Q: Should rockfall fence or active slope net be selected for new mountain roads? How to distinguish and choose?
A: Rockfall fence is a foot-of-slope interception product, designed to catch rocks that have already fallen, suitable for road sections with large mountain drop and abundant gravel. Active slope net is attached to mountain surfaces to fix loose rocks and prevent rockfall at source. The two products can be matched according to the weathering degree of mountain rocks.
Q: Will the service life of rockfall fence be shortened when installed in rainy and humid mountain areas?
A: Products with zinc-aluminum alloy coating have stronger resistance to damp corrosion, and can be used stably for 8–12 years in humid mountainous areas. Ordinary hot-dip galvanized products can serve 5–8 years under humid conditions. Its anti-rust performance is far superior to ordinary black iron wire mesh, and large-area rust penetration and damage rarely occur.
Q: Is the fence firmly installed on slopes covered with broken rocks and large uneven undulations? Will it shift under impact?
A: The fence adopts an integrated flexible structure fixed by multiple support ropes and multi-point anchors. Impact force is evenly distributed when hit by rocks without local loosening. It can be stably installed on steep slopes and uneven rock surfaces covered with gravel, resisting vibration and continuous impact without displacement.
