Heavy-Duty Gabion Cages for Sale | Durable & Affordable

For marine environments, we recommend 3.4mm wire with high-grade galvanization (minimum 290 g/m²) or PVC coating for enhanced corrosion resistance. According to ASTM A975 specifications, marine-grade gabions should withstand salt spray testing for 4000+ hours without significant corrosion.

The EN 10223-3 standard requires tensile strength between 350-500 MPa for standard gabions. Heavy-duty applications demand 450-550 MPa. Our gabion boxes exceed these standards with reinforced selvedge wires at panel edges and double-twist hexagonal mesh construction for superior structural integrity.

Clay soils require wider foundations with geotextile separation layers to prevent pore pressure buildup. Sandy soils need deeper toe-in installations and potentially gabion mattresses as base reinforcement. Cohesive soils may require reduced batter angles and additional drainage behind structures. Engineering surveys should always precede gabion installation.

Our standard galvanized gabions provide 25-35 years of service. Heavy galvanization extends this to 40+ years. PVC-coated units in severe environments last 50+ years. Actual lifespan depends on water chemistry, impact exposure, and UV radiation levels. Regular inspections are recommended at 5-year intervals.

Optimal fill material should be 1.25-1.5 times the mesh opening size. For standard 80×100mm mesh, use 100-150mm diameter rocks. Angular stone provides superior interlock compared to rounded river stone. Avoid crushed material with high fines content which can accelerate deterioration through chemical leaching and pore pressure.

Key standards include EN 10223-3 (Europe), ASTM A975 (US), and AS 4671 (Australia). Testing regimes typically include tensile strength evaluation, zinc coating adherence checks, accelerated corrosion testing, and mesh deformation resistance measurements following established protocols in civil engineering materials certification.

Structural connections require high-tensile steel spiral binders or corrosion-resistant lacing wire with diameter matching the mesh wires. Adjacent baskets should be secured with every third mesh opening. Foundation anchoring typically employs earth anchors or driven steel pins at 1m intervals. For tall walls (>3m), we recommend internal tiebacks and stepped foundations.
