Engineered for longevity and aesthetic versatility, JOESCO’s Galfan® Zn95/Al5 welded gabion baskets combine military-grade corrosion resistance with modular design for sloped gardens, retaining walls, and flood control. Compliant with EN 10244-2 Class A standards, these gabions redefine durability in harsh environments.
Core Specifications & Features
Material & Coating
Wire Composition: 95% zinc + 5% aluminum-mischmetal alloy (Galfan® coating), exceeding traditional galvanized corrosion resistance by 3×.
Wire Diameter: 4.0mm (mesh wire), 5.0mm (helical joints), ensuring tensile strength of 380–500 N/mm².
Mesh Aperture: 50×100mm (standard) or customizable to 60×80mm–120×150mm for varied stone visibility.
Dimensions & Structure
Modular panels: 2m×1m×1m (expandable to 4m×1m×1m) with helical binders for tool-free assembly.
Triple-layer corrosion protection: Galfan® alloy base + PVC coating (optional) + ISO 10244-2 certification.
Certifications
Complies with EN 10244-2 Class A, ASTM A975, and ISO 10244-2 for coastal/marine applications.
Advantages Over Traditional Gabions
Unmatched Durability
50+ year design life in salt-spray environments (vs. 20–30 years for standard galvanized).
Resists UV degradation, frost, and soil acidity with ≤0.005% annual coating loss.
Eco-Friendly Design
Permeable structure promotes natural drainage and vegetation growth (ideal for terraced gardens).
100% recyclable materials reduce carbon footprint by 40% vs. concrete walls.
Cost-Effective Installation
Pre-fabricated panels assemble in <30 minutes—no welding or heavy machinery required.
Foldable design cuts transport costs by 60% compared to rigid alternatives.
Aesthetic Flexibility
Stone-filled baskets blend with natural landscapes or urban designs (PVC-coated options in green/black).
Applications
Slope Stabilization
Retains 70° inclines with 90% erosion reduction (validated in 2024 Colorado landslides).
Architectural Landscaping
Creates decorative partitions, garden benches, or waterfall features with 50–250mm stones.
Flood Mitigation
Acts as a permeable barrier in floodplains, withstanding 3 m/s water velocity.
Coastal Protection
Saltwater-resistant Galfan® coating prevents pitting corrosion in tidal zones.
Installation Guide
Site Preparation
Compact soil to 95% density; lay geotextile fabric to prevent soil migration.
Assembly & Filling
Unfold panels → connect with spiral binders → layer stones (20–30% overfill for settling).
Maintenance
Annual inspection: Check for PVC abrasion or wire exposure; re-tighten binders post-floods.
FAQs
Q: Can Galfan® gabions support vertical gardens?
A: Yes! The 50×100mm mesh allows ivy/fern roots to anchor securely.
Q: Are custom sizes available?
A: JOESCO offers bespoke dimensions (e.g., 3m×0.5m×1m) with a 15-day lead time.
