GALFAN GABIONS: DURABLE, CORROSION-RESISTANT SOLUTIONS FOR MODERN CIVIL ENGINEERING Galfan gabions represent a superior evolution in geotechnical reinforcement systems, combining the proven structural integrity of traditional wire mesh baskets with advanced zinc-aluminum alloy coating technology. These engineered structures are ideal for applications requiring long-term durability in harsh environmental conditions—from coastal erosion control to industrial site stabilization. Unlike conventional galvanized alternatives, Galfan-coated gabions offer enhanced protection against rust and degradation, making them a preferred choice for civil engineers, landscape architects, and infrastructure developers worldwide. Key Features: - Advanced Galfan Coating (Zn-5% Al-Mischmetal Alloy): Provides up to 3x better corrosion resistance than standard galvanization in salt spray tests and up to 2x improvement in sulfur dioxide exposure environments. - Uniform Wire Mesh Construction: Double-twisted hexagonal pattern ensures high tensile strength and non-raveling performance under dynamic stress. - Consistent Coating Weight: Meets ASTM A975-97 standards with 0.80 oz/sf coating weight across all wire diameters (0.120", 0.153", 0.091"), ensuring predictable longevity. - Enhanced Structural Integrity: Internal diaphragms divide larger units into cells, preventing bulging and improving load distribution—ideal for retaining walls and slope stabilization. - Customizable Dimensions: Available in standard sizes (e.g., 6x3x3 ft, 9x3x3 ft) or custom jumbo configurations to meet project-specific requirements. Detailed Description: Manufactured from carbon steel wire with a proprietary Galfan coating, these gabion baskets are designed for maximum resilience in both rural and marine settings. The coating’s unique lamellar microstructure allows aluminum enrichment over time, creating a self-healing barrier that becomes more protective as exposure increases—not less. This parabolic corrosion behavior contrasts sharply with linear degradation seen in pure zinc coatings. Each unit is fabricated with precise tolerances (+/- 5%) and meets stringent industry benchmarks such as ASTM A641 for soft temper wire, ASTM A90 for coating weight, and ASTM A370 for elongation (minimum 12%). The mesh opening size of 8 cm x 10 cm (3¼” x 4½”) provides optimal stone retention while allowing water permeability—a critical factor in drainage-heavy applications like streambank protection or flood mitigation systems. Applications: These gabion structures are widely used in civil engineering projects including: - Retaining walls for roadways, railways, and residential developments - Erosion control along riverbanks, shorelines, and coastal areas - Slope stabilization on highways, embankments, and mining sites - Stormwater management and flood defense infrastructure - Decorative landscaping features where functionality and aesthetics intersect User Testimonials: Engineers report significantly extended service life when compared to galvanized counterparts—especially in saltwater environments where traditional systems fail within a decade. Contractors appreciate the ease of assembly using lacing wires or approved fasteners like TIGER-TIES®. Site supervisors note reduced maintenance needs and improved safety due to consistent structural performance even after prolonged exposure to UV radiation, moisture, and temperature fluctuations. Common Questions: What makes Galfan different from regular galvanized wire? The zinc-aluminum alloy forms a denser, more uniform layer that resists pitting and flaking, especially in aggressive environments like marine zones or urban industrial areas. Can I use crushed stone instead of natural rock fill? No—only clean, hard stones between 4–8 inches are recommended to ensure proper compaction and avoid premature wear on the mesh. Are there any special installation tips for multi-layered walls? Yes—install connecting wires every vertical lift during filling to maintain alignment and prevent lateral movement. Use corner closure tools for seamless jointing between adjacent units. Is this suitable for earthquake-prone regions? Absolutely—the flexible nature of the double-twisted mesh allows controlled deformation without catastrophic failure, making it highly effective in seismic zones.
