Barriers Rockfall protection

barriers

Rockfall barrier systems are designed to intercept falling rocks which have detached from the rock face above them and pose a threat for humans or human structures.

Rockfall barriers are complex structures of steel cables, connections of steel cables to structural elements, energy absorbing devices and anchorages, capable of high deformation capacities.

Their versatility allows them to be used along side different positions, to protect built-up areas, roads, or in coupling with other passive interventions (such as nettings), even in narrow spaces.

ATTRIBUTES

- The size, the quality of materials and their technical specifications are standardised and certified.
- Very effective for rockfall protection and environmentally harmless.
- Easy to install due to the modular system structure.
- Easy and economically maintained.
- Is a flexible system with low impact forces on the individual components.
- They deform limited after the impact of the rock and maintain adequate levels of protective shield in their flexible screen buffer.
