We offer Rockfall Netting Barrier used to control falling rocks on slopes, highways, railways, and construction areas. The system consists of steel wire mesh, steel support posts, anchor cables, and energy dissipation rings to absorb impact energy. Standard mesh openings range from 50 × 50 mm to 300 × 300 mm, with wire diameters from 3 mm to 8 mm. Types include Passive Rockfall Barriers installed along slopes to intercept falling rocks, Draped Wire Mesh Systems placed directly on rock surfaces for stabilization, and High-Energy Rockfall Barriers designed for impact resistance levels from 500 kJ to 5000 kJ. These systems are used for slope stabilization, road protection, railway protection, and rockfall control zones.

Type
- Passive Rockfall Barrier: Passive rockfall barriers are placed at the slope base or roadside to stop falling rocks. The structure includes steel posts, wire mesh panels, top and bottom support cables, anchor cables, and energy dissipation rings. Barrier height ranges from 2 m to 6 m, with post spacing from 5 m to 12 m. Impact capacity under EN 17472 is 100 kJ to 5000 kJ, and they are used on highways, railways, and slope protection areas.
- Draped Wire Mesh Rockfall: Draped wire mesh systems place steel wire mesh on rock surfaces to control rock movement on slopes. The structure includes mesh rolls, crest anchor cables, anchor bolts, and connection wires. Mesh roll width ranges from 2 m to 5 m, with coverage lengths from 20 m to 100 m. The system guides rocks down the slope and is used on slopes 30° to 70°.
- High-Energy Rockfall Barrier: High-energy rockfall barriers stop large rocks with high impact energy. The structure includes high-tensile steel mesh, reinforced steel posts, support cables, anchor systems, and energy dissipation devices. Barrier height ranges from 3 m to 6 m, with support cable diameters from 12 mm to 22 mm. Under EN 17472, impact resistance is 500 kJ to 5000 kJ, suitable for mountain roads, tunnels, and railways.
- Hybrid Rockfall Protection: Hybrid rockfall protection systems combine draped mesh and passive barriers in one system. The upper slope uses draped wire mesh, while the lower section installs a rockfall barrier to stop remaining rocks. Mesh opening sizes range from 50 × 50 mm to 300 × 300 mm, with wire diameters from 3 mm to 8 mm. This system is used for long slopes and areas with high rockfall risk.
