Product Introduction
Rockfall Fence is made of high quality carbon steel or stainless steel, including steel wire rope net, steel ring net, tecco mesh, spider spiral rope mesh, chain link wire mesh and hexagonal wire mesh. With galvanized, powder coated or PVC coated surface, they're corrosion and rust resistant. The common rockfall barrier combination is steel wire rope net with chain link mesh, it can be used as active or passive rockfall barrier for slope or mountain protection to minimize the impact of natural disasters, such as landslide, debris flow and so on.
Product Features
● High tensile strength.
● Various types for choice.
● Corrosion and rust resistance.
● Anti harsh environment.
● Durable and long service life.
Product Installation
The system, when it arrives on site, includes all posts, base plates, netting, braking systems, anchor cables and ground anchors (for typical ground conditions). Ideally suited where space is limited these barrier fences are easy to install by qualified rope access contractors experienced in drilling and working on rock faces. After impact maintenance is a simple process of removing the collected debris and replacing the compression brakes and checking the serviceability of the remaining components. Rockfall barriers to be used to protect most road and rail infrastructure works as well as protection of buildings, pipelines, in mine works and where rockfall is identified as a hazard.

Product Application
When a solution cannot be implemented in the detachment zone, possibly due to technical, topographic, access or economic issues, other options need to be considered. In these cases, a cost-effective solution is often provided by installing dynamic rockfall barriers within the transit or impact zones.
These dynamic barriers or ‘catch fences’ are positioned to intercept and stop falling rocks and boulders.
● Slope protection.
● Mountain protection.
● Vegetation protection.
● Road protection.
