Flexible Passive Protection Nets consist of steel posts, wire rope nets, support ropes, anchor systems, and deformation rings. For intercepting small rocks, an additional wire mesh layer can be added. Notably, hexagonal wire mesh slope protection traps small fragmented debris, while ring net slope protection (using high-tensile steel rings) demonstrates superior impact resistance-sustaining peak stresses up to 675 MPa. Compared to rigid retaining walls, Flexible Passive Protection Nets require shorter construction periods and lower costs.

Product Advantages
The flexible structure absorbs impact energy efficiently through deformation rings. Installation requires no large-scale excavation-100 meters can be completed by 8 workers within 10 days. The modular design adapts to any slope terrain, while galvanizing ensures long-term durability.
Main Applications
Flexible Passive Protection Nets are ideal for intercepting rockfalls, debris flows, and avalanches. They protect highways, railways, mining areas, hydropower projects, and buildings at the foot of steep cliffs.
Frequently Asked Questions (FAQ)
Q: What distinguishes active from passive protection?
A: Active nets are tensioned onto slopes to prevent rockfalls. Passive systems are installed at slope bases to intercept falling rocks.
Q: What impact energy can these systems handle?
A: Standard systems handle 150kJ to 2000kJ, with high-performance versions tested up to 3000kJ.
