SNS Flexible Galvanized Slope Protection Netting / Passive Rockfall
Barrier System
Product description:
Passive rockfall barrier system is installed bottom of the mountain
or slope to reduce and block the rockfalls and stones. When the
stones, rocks, snows are falling down the mountain or slopes, the
passive rockfall barrier system can reduce the impact of the
rockfalls and protect the people and properties' safety.
Main types of passive rockfall barrier systems are including steel
wire rope net and steel ring net.
Steel wire rope net. steel wire rope net can not only used for
active rockfall barrier system, but also the passive rockfall
barrier system. It is mainly composed of steel wire rope net,
decompression rings, supporting rope, sewing rope and steel column.
It has high tensile strength and can block the rockfalls within 750
kJ.
Steel wire ring net. Steel ring net is made of high quality hot
dipped galvanized wire into circles. Different circle quantity have
different block capacity. The steel ring net can block the
rockfalls within 2000 kJ. Steel ring net system is commonly made of
steel ring net, supporting rope, anchor rope, sewing rope and metal
column.

Features of rockfall netting
Resistant to corrosion, rust, oxidation and damage.
Stable structure, smooth surface, uniform mesh size, high tensile
strength.
Allow vegetation regrowth.
Flexible in all direction and would not spread when it is broke.
Easy to transport and install.
Galvanized mesh and PVC coated mesh have longer life, low cost.
Applications of rockfall netting
Prevent rocks and debris from falling onto roads and railways.
Prevent landslides.
Protection of infrastructure beneath slopes.
