Attenuator Fence: Managing Rockfall Safely

BMP attenuator fence, also known as hybrid barriers, are crucial for managing rockfalls on slopes. They ensure rocks slow down and stop safely with enough “run-out” space beneath. Our BMP rockfall attenuator barriers combine a dynamic rockfall barrier’s structure with the low-maintenance benefits of drapery mesh. They mainly mitigate passive rockfall hazards. Unlike traditional setups, these fences have a longer mesh that drapes down slopes to slow falling rocks effectively.

Why Choose BMP Rockfall Attenuator Fence?

Effective Mitigation: They play a crucial role in passive rockfall hazard mitigation by reducing the momentum of falling rocks.
Durable Construction: The panels and support components are robust enough to withstand multiple, near-simultaneous impacts without significant loss of height or capacity.
Hybrid Design: Features an intercepting panel drape made using HEA panel or ring nets, which absorb high dynamic impacts and guide the rocks down the slope without halting their motion.
Low Maintenance: Combines the energy absorption capabilities of a dynamic rockfall barrier with the low upkeep benefits of drapery mesh.
Comprehensive Structure: Includes a ‘skeleton’ structure equipped with steel posts, upper longitudinal ropes, cable anchors, and all necessary accessories.
Customization: Tailored to meet specific site conditions and recommended for installation by specialist contractors.

BMP’s rockfall attenuator fences are ideal for areas requiring dependable rockfall protection with minimal ongoing maintenance. Their ability to withstand significant impacts while managing rock descent makes them a top choice for safeguarding vulnerable slopes.

How it works

Rockfall attenuator fences made of wire rope are a highly effective solution for minimizing the impact of rockfalls in mountainous areas. These fences are the most common type of rockfall barrier and come in two main varieties: galvanized wire rope and PVC-coated wire rope. The wire ropes cross over each other and are securely fastened with clips, offering greater tensile strength than standard steel wires. While the steel wire rope can be used alone to block large stones, it is often paired with chain link fences or hexagonal wire mesh to stop both large and small rocks. Additionally, these fences can enhance the aesthetic of drab mountainous or surrounding areas, providing a pleasing view.
