This Rock Fall Netting is specially developed for slopes covered with thick loose soil, and the Rock Fall Netting adopts segmented meshes with different apertures.the bottom fine mesh of Rock Fall Netting stops continuous sediment loss while upper wire rope mesh catches falling rocks. All components of the Rock Fall Netting receive unified anti-corrosion treatment for mountain slopes with persistent gravel sliding risks.

Product Advantages
1.Segmented mesh layout solves dual hazards of soil slipping and rock falling, one set of system meets two protection demands.
2.Strict wire diameter tolerance control stabilizes the tensile performance of the whole netting, extending long-term service life to 30–50 years.
3.Lightweight prefabricated parts adapt to undulating loose soil slopes without large-area ground leveling.
Manufacturing Technology
1.High-carbon steel wire undergoes cold drawing first, then twisted into standard wire ropes by fully automatic twisting equipment.
2.Double-twist hexagonal mesh is produced with double-lock twisting structure to avoid crack expansion after local damage.
3.Finished components are immersed in galvanizing solution once for overall anti-corrosion treatment without post-welding supplementary coating.
FAQ
Q: Will soil and fine gravel leak continuously from the mesh on slopes with thick loose soil?
A: No. It adopts layered mesh layout. The bottom dense double-twist hexagonal mesh blocks sediment and tiny gravel, while the upper wire rope mesh intercepts falling boulders to realize dual protection against soil sliding and rockfall.
Q: Will the galvanized coating peel off after long-term outdoor exposure?
A: All components are integrally hot-dip galvanized in one process without supplementary coating after welding. The zinc layer closely bonds with steel base and will not peel within 30–50 years under normal service conditions.
Q: Can the flexible net fit uneven undulating soil slopes?
A: Prefabricated components are lightweight. The flexible net can closely attach to irregular slopes, and no large-area leveling or soil compaction is required during construction for soft undulating mountain slopes.
