Ring Mesh System

Ring Net System Withstands Maximum Sudden Impact Among Rockfall Systems

With high strain performance, it is ideal for situations where there is a high risk of sudden impacts such as rockfalls, landslides, debris flows and mud flows. In addition, it also used to face rock slopes featuring large rock masses prone to failure as it can accommodate these high local stresses without sustaining damage. It can be installed with a low outlay of materials and man hours, which greatly reduces costs and construction time.

The technical performance of the system is dependent upon wire standard diameter, bundle configurations and the number of connection points to adjacent rings within the net panel.

It generally consists of ring net, steel posts, brake rings, rope anchors and support ropes. Of which, ring net is the most important part of the whole system. The ring is manufactured by single wire with a tensile strength of 1770 N/mm2 and two ends of lap length not less than 100 mm. Twine together ring with steel or aluminum alloy fasteners in at least three hoop uniformly distributed locking, and one is located at the two ends of the joint, in addition to the edge ring hole, 4 rings each with its surrounding buckled together. Single tool can replace installation, repair and parts of the system. It is linked together by rings made of high tensile-strength steel wire which between 5 and 19 spirals are bundled together. It has good buffering performance through its deformation and outstanding energy absorption properties. As the ring net has a large mesh opening and cannot stop the movement of small rocks, it generally works with Rockcon® mesh or hexagonal mesh to increase the stability of rock slope.

Specification

Notes:

Let's take the ring net size R7/3/350 as an example. Where R stands for ring net, 7 represents 7 circles, 3 stands for wire diameter, expressed in mm and 350 stands for ring diameter, expressed in mm.

High-tensile steel wire net

Protection against dynamic loads up to 8000 kJ. Some of the energy is dissipated by means of elastic/plastic net deformation while the majority is dissipated by the braking elements.

Low deformation

Testing that replicates field conditions has confirmed that this solution offers the lowest deflection on the market. This makes it ideal for installation adjacent to the object or infrastructure at risk.

Pre-assembled

The posts are delivered to the construction site as modules with pre-installed bundles of netting for easy installation (RXE-500 to RXE-3000 systems). This significantly reduces the installation time.

U-brake with stainless steel

This component enables linear energy dissipation and is easily accessible for inspection and maintenance. Stainless steel makes the brake extremely durable even when subjected to strain.

Lightweight and unobtrusive

The low weight of the barrier means that it can be easily installed. With its high-tensile steel wire and innovative design, this solution conserves materials, protects the environment and is virtually invisible from a distance.

First-class corrosion protection

The corrosion protection of our systems will last for generations. This means that our customers benefit from particularly low maintenance costs.
