Performance Characteristics of Tecco High-Strength Steel Mesh

TECCO high-strength steel wire mesh (usually also known as TECCO mesh or TECCO system) is a high-performance active protection system widely used in the fields of geotechnical engineering and slope protection.

1. Extremely high strength and toughness

• High strength steel wire: High strength steel wire made of special alloy, with a tensile strength much higher than ordinary steel wire (usually up to 1770 MPa or more).

• High system bearing capacity: The entire protective net system (including nets, support ropes, anchor rods) can withstand loads of up to 300-500 kN or higher, effectively intercepting falling rocks and buffering impacts.

• Good ductility: When subjected to a huge impact, the system can absorb and disperse energy through its own elastic-plastic deformation ("overcoming rigidity with softness"), avoiding brittle failure.

2. Excellent anti-corrosion performance

Gao Erfan ®  (Galfan) coating: Zinc aluminum alloy (5% aluminum zinc alloy+rare earth element) coating is usually used. The anti-corrosion life of this coating is 2-3 times that of pure hot-dip galvanizing, and it can provide long-term protection even in harsh environments, ensuring the long-term safety of the project.

3. Unique mesh structure

• Diamond shaped mesh: The standard TECCO mesh has a diamond shaped mesh with a stable structure.

• Twisted rope weaving: Steel wire is woven through a special twisting process, with a flat mesh surface, good flexibility, and strong adhesion to the slope surface.

4. Active protection mechanism

• Comprehensive pre tensioning: During installation, the entire network system is pre tensioned to tightly adhere to the slope, forming a continuous active reinforcement layer.

• Inhibiting weathering and local collapse: By surface compaction, it is possible to prevent the weathering, peeling, and fragmentation of slope rock and soil, and anchor local instability on stable bedrock.

5. Modularity and construction convenience

• Standardized components: The system consists of standardized components such as mesh, boundary ropes, support ropes, suture ropes, anchor rods, etc., with clear design.

• Installation is relatively flexible: it can be cut and spliced according to terrain and engineering requirements, adapting to complex slope shapes.

• Lightweight: Compared to rigid protective structures such as concrete spray anchors, the material is lightweight, and transportation and installation cause less disturbance to the mountain.

6. Eco friendliness

• Transparency and permeability: The mesh structure allows light to penetrate and rainwater to infiltrate, which is beneficial for the natural restoration of slope vegetation.

• Can be used as a plant substrate carrier: often used in conjunction with geogrids, plant bags, etc., to stabilize slopes while promoting ecological greening and achieving the integration of engineering and ecology.

7. Wide range of application scenarios

• Slope stability and reinforcement: suitable for rock and soil slopes to prevent shallow landslides and peeling.

• Rockfall protection: used to intercept falling rocks on mountain slopes and protect roads, railways, buildings, etc. below.

• Tunnel entrance protection: prevent falling rocks on the slope of the entrance.

• Ecological restoration project: Combining with greening technology to carry out wound greening.

The core advantages of TECCO high-strength steel wire mesh lie in its "high strength, high toughness, long service life, active reinforcement, and ecological compatibility". It is not just a simple net, but a complete engineering system that provides safe, reliable, durable, and environmentally friendly flexible protection solutions for geotechnical slopes through high-tech materials and exquisite design.
