Product Introduction

The technology leader ensuring safety on roads and worksites – Sungwon Safety Co., Ltd.

The Wiring Net is a steel mesh structure designed to protect roads and facilities from landslides and falling rocks. Sungwon Safety Co., Ltd.’s Wiring Net provides exceptional tensile strength and durability, effectively dispersing impact forces and offering superior resistance to control rockfalls efficiently.

Method Overview

A highly stable and durable rockfall prevention method that effectively disperses rockfall energy through a unique ring structure made of high-strength wire rope and flexible shock absorption technology.

Features & Benefits

Efficient Rockfall Blocking Structure

The first and second wire nets, composed of multiple wire rings, are interconnected and cross each other to form a dense and highly stable structure.

Excellent Structural Stability

Firmly secured through coupling panels and embedded posts, the system is strongly anchored to the slope ground, maintaining robust stability even under ground deformation or movement.

Ease and Efficiency of Installation

Manufactured in unit modules at the factory, it allows for easy on-site installation tailored to field conditions, reducing construction time and enabling efficient operation.

Durability and Long-Term Stability

The combination of the wire net coupling system and embedded posts effectively absorbs and disperses the impact energy from falling rocks, making it adaptable to various terrains and environmental conditions.

Reduced Maintenance Costs

It allows partial repair or replacement in unit modules, reducing maintenance needs and lowering overall costs.

Performance & Excellence

Indoor Tensile Test

Purpose: To evaluate the fundamental structural performance through quantitative comparison under identical conditions.
Test Method: Tensile test based on a hydraulic system.

Under the same load condition (40 kN), the proposed product exhibited only about 70% of the displacement compared to the general rockfall protection net, demonstrating superior energy resistance. In addition, it achieved both structural strength and ductility with approximately 30% less displacement than the conventional net, indicating excellent resistance to rockfall impact and enhanced durability when applied in the field.

Numerical Analysis Results

Purpose: To evaluate structural stability and the predictive performance of rockfall energy based on indoor test results.
Analysis Scope: A total of four models analyzed — laboratory-scale and field-scale specifications.

- Under the same energy condition (29.23 kJ), the proposed product exhibited approximately 36% less displacement, achieving an average 156% higher load resistance capacity.
- Overall, the proposed product demonstrated approximately 60–65% lower displacement compared to the reference product, exhibiting superior resistance performance under identical rockfall energy conditions.

Field Dynamic Test Results

Purpose: To evaluate the fundamental structural performance through quantitative comparison under identical conditions.
Condition: 0.5-ton concrete block, drop height of 3 m → 14.72 kJ energy.

Items	General Rockfall Protection Net (A-Type)	New Model (Applied with Wire Net)
Maximum Displacement (cm)	88.5	61.0
Average Deformation Ratio	Reference Value	Approximately 69%Level

Considering the partial detachment of some joints and the inertia effects of the falling object during the test, the results are deemed to accurately reflect the actual energy absorption performance under real field conditions. Under the same conditions (14.72 kJ rockfall energy), the proposed product recorded a maximum displacement of 61 cm, which is approximately 11% greater than the predicted value (55 cm) from numerical analysis, but only about 69% of the displacement observed in the comparison product (88.5 cm). These findings confirm that the proposed product resists rockfall energy more efficiently and effectively.

Product Structure

1. Dual Wire Net Structure

By continuously interlacing a single wire rope, the first wire net (vertical direction) and the second wire net (horizontal direction) are formed, ensuring strong structural ductility and enhanced overall integrity.

2. Ferrule Fixing Method

Each intersection point is bound using ferrule components, preventing slippage caused by external forces and minimizing deformation of the net.

3. Integrated Bottom Embedded Support

The bottom section of the wire net is integrated with the embedded support structure, allowing impact-induced deformation to be distributed gradually. This design prevents damage and ensures long-term safety and stability.
