Structure
- Ring wire mesh. Combined with steel ring nets, it blocks small rocks or soil during natural disasters (mesh size is generally 60 × 80 mm or 80 × 100 mm).
- Steel ring net. Made of high-strength steel wire twisted into circles, circles are interconnected to form a steel ring net, with high load-bearing capacity and more flexibility than steel wire rope nets.
- Pressure relief ring. Place along the steel wire ring net to reduce pressure. Made of hot-dip galvanized metal, it is corrosion-resistant and rust-proof.
- Support rope: Made of stainless steel wire rope, it has high tensile strength, supports the steel wire rope and pressure relief ring, and can withstand significant impact forces.
- Steel column. Installed on the base foundation, it supports the steel wire ring net, and is corrosion-resistant and rust-proof, with high tensile strength. Arrangement can be adjusted according to terrain and environment.
- Base foundation. It is used to secure the steel column, treated with hot-dip galvanization to prevent corrosion and rust.

Advantages
- Suitable for rock slopes of any steepness, without considering the physical and mechanical properties of the ground.
- Only a minimal number of anchor points are needed to secure the top support rope at the edge of the slope.
- A top-down installation method is used to ensure that the installation personnel are always in a safe area.
- The accumulation area of debris at the bottom of the slope is easy to clean mechanically, without the need for special equipment.
- The rockfall curtain requires no maintenance.
- There are no weak points in the design.
