Heavy Duty Galfan Gabion Mattress for Erosion Control | ASTM A975 Standard

Proven Geotechnical Solutions for Riverbank Stabilization, Coastal Protection, and Slope Erosion Control.

## Product Overview

Our Heavy Duty Galfan Gabion Mattress is a premium, engineered rock-filled wire mesh basket system designed for long-term erosion control and hydraulic engineering. Manufactured strictly in accordance with international ASTM A975 standards, these mattresses offer superior flexibility, permeability, and high corrosion resistance compared to traditional concrete or riprap structures.

By utilizing Galfan coating (95% Zinc + 5% Al-MM Alloy), our gabion mattresses deliver up to 3x to 4x the corrosion life of standard heavy galvanized steel wire, making them the ultimate choice for harsh maritime, riverine, and coastal environments.

## Key Technical Specifications (ASTM A975 Compliant)

To ensure structural integrity in high-shear stress environments, our Galfan gabion mattresses are built to the following technical parameters:

Optional: PVC / PE eco-friendly coating can be applied over the Galfan wire for added resistance against UV radiation and chemical abrasion in highly acidic or polluted waters.

## Why Choose Galfan Coating Over Standard Galvanizing?

When engineering long-lasting erosion control structures, material degradation is the biggest enemy. Galfan wire provides a unique microstructural advantage:

• Self-Healing Properties: The aluminum-zinc alloy forms a passive protective layer that self-heals when scratched during rock filling or hydraulic impact.

• Superior Ductility: The coating remains tightly bonded to the steel core even after the double-twisting manufacturing process, preventing cracks or flaking.

• Extended Service Life: Designed for a design life exceeding 50 to 100 years in typical freshwater and mild marine environments.

## Core Applications & Engineering Scenarios

Our heavy-duty Reno mattresses are widely deployed across infrastructure projects worldwide:

• Riverbank & Channel Linings: Prevents scour and erosion caused by high-velocity water flows.

• Coastal Erosion Control: Dissipates wave energy on shorelines, protecting seaside infrastructure.

• Bridge Pier Protection: Safeguards critical bridge foundations from hazardous riverbed scouring.

• Slope Stabilization: Reinforces mountain slopes and embankments, retaining soil while allowing natural drainage.

## Advantages for Civil Engineering Projects

1. High Permeability & Natural Drainage

The rock-filled matrix naturally allows water to pass through, eliminating hydrostatic pressure buildup behind the structure. Over time, sediment deposits within the stones, promoting vegetation growth and ecological restoration.

2. Flexible Monolithic Structure

Unlike rigid concrete linings, the double-twisted hexagonal mesh accommodates differential ground settlement without structural fracturing. It deforms safely while maintaining its retaining integrity.

3. Cost-Effective & Easy Installation

No specialized heavy machinery or skilled labor is required for assembly. Unfold, bind, fill with locally sourced rocks, and secure. This significantly reduces overall project timelines and labor costs.
