Galfan Coated Woven Gabion Wall for Heavy-Duty Retaining Wall Systems

Engineered for superior earth retention and soil stabilization, Galfan Coated Woven Gabion Walls offer a flexible, permeable, and monolithic solution for civil engineering and landscape infrastructure. Manufactured from high-tensile steel wire woven into a double-twisted hexagonal mesh, these gabions are treated with an advanced Galfan (95% Zinc + 5% Aluminum-Mischmetal alloy) coating. This ensures 2 to 3 times the corrosion resistance of traditional hot-dip galvanized steel, making them the industry standard for retaining walls, channel linings, and slope reinforcement.

Key Advantages of Galfan Woven Gabions

• Triple the Service Life: The eutectic Galfan alloy provides sacrificial cathodic protection combined with an aluminum oxide barrier, preventing rust even in acidic soil and marine environments.

• Flexible & Non-Raveling Structure: The double-twisted hexagonal weave allows the structure to settle differential ground movements without structural fracture or unravelling if a wire is cut.

• Natural Drainage & Permeability: Acts as a self-draining retaining wall, dissipating hydrostatic pressure behind the wall face to eliminate pore pressure build-up without requiring complex drainage pipes.

• Eco-Friendly & Aesthetic Integration: Voids within the stone fill naturally trap soil and promote vegetation growth over time, blending seamlessly into the natural topography.

Primary Applications

• Gravity Retaining Walls: High-load hillside slope stabilization, highway embankments, and railway cuttings.

• Hydraulic & Marine Works: Riverbank protection, weir structures, bridge abutments, and coastal erosion control.

• Perimeter Fencing & Sound Barriers: Architectural retaining elements and environmental noise reduction walls.

Installation Guidelines

1. Assembly: Unfold the flat-packed gabion units on a level surface, fold up the side panels, and lace the vertical edges securely using Galfan tie wire or pneumatic C-rings.

2. Placement & Anchoring: Align the assembled cages along the excavated foundation line and drive ground stakes to maintain straight alignment.

3. Stone Filling: Fill the cages in one-third lifts using hard, angular, weather-resistant stone (100 mm to 200 mm diameter). Install internal bracing wires between lifts to prevent outward panel bulging.

4. Lid Closure: Pull the lid tightly over the stone fill, align all edges, and tie off securely along the perimeter and diaphragm walls.
