Rockfall Barrier System - Active and Passive Protection Types

Rockfall barrier system is important component in the mountain safety construction and slope protection project. They can prevent the stones and soils from falling down to the ground and hurt people or properties. Additional, they can reduce the force caused by the landslide, debris flow, snow avalanche and other natural hazards.

The rockfall barrier system can be divided into active rockfall barrier system and passive rockfall barrier system. Hexagonal wire mesh can not only used in the active rockfall barrier system, it can also be used in the passive rockfall barrier system.

Active rockfall barrier system

The hexagonal wire mesh is covering the mountains.

Cover the hexagonal wire mesh onto the mountain and sewing neighbor meshes with sewing rope and fastened to the mountain firmly by the anchor and anchor plate. Hexagonal wire mesh has hexagonal meshes, which can ensure the good air, sunlight and water circulation for the healthily grow of plants. Additional, the hexagonal wire mesh are made of corrosive resistant hot dipped galvanized steel wires, which can ensure the good appearance and perfect performance even in the harsh environments.

Passive rockfall barrier system

Hexagonal wire meshes are installed combined with steel ring net.

Passive rockfall barrier system is commonly installed at the foot of mountains and slope. To prevent stones, soil or snows from rolling to the road and hurt people or vehicles. Hexagonal wire mesh is commonly used with steel ring net. The steel ring net can prevent large stones and the hexagonal wire mesh can block little stone or detritus. Both the hexagonal wire mesh and steel ring net has higher tensile strength to bear the high impact from mountains and natural hazards. It can supply double protection for people and properties.

Features of hexagonal wire mesh

  • High tensile strength to bear the huge impact from stones and natural hazards.
  • Corrosive resistant material to maintain the long service life of products.
  • Flexible application. The hexagonal wire mesh can not only be installed on the mountains to prevent stones from falling down, it can also be installed at the foot of mountains to reduce the impact from the falling stones for the people and properties.
  • Easy to install. The installation of hexagonal wire mesh is easy and fast compared with other rockfall barrier system.
  • Ecological. The hexagonal wire mesh will not limit the plant growth on the mountain. It can supply good circulation of air, water and sunlight.
