Will your galvanized gabion boxes rust and what is the expected lifespan in river environments?

Our hot-dipped galvanized gabion boxes (≥250g/m² zinc coating, EN 10244-2 Class A) have a design life of 25-50 years in freshwater river environments (pH 6-8). The zinc coating corrodes sacrificially at a predictable rate of approximately 5-10g/m² per year in clean freshwater, giving a coating life of 25+ years even before considering the underlying steel. In acidic water (pH <6) or brackish environments, we recommend PVC coated (0.5mm over galvanized, 2,000+ hours salt spray) or Galfan (Zn-5%Al) coated options which extend service life 2-3×. After the gabion fills with sediment and vegetation establishes, a natural protective layer forms that further reduces corrosion rates. We provide coating thickness certificates with every shipment.

What is the recommended stone size and gradation for filling your gabion boxes?

Stone fill should be 1.5-2× the mesh aperture in minimum dimension to prevent washout. For our 80×100mm mesh gabion boxes: minimum stone diameter 120mm, maximum 250mm. The stone should be hard, durable, and weather-resistant (建议: granite, basalt, limestone with UCS ≥50 MPa). Stone gradation should be well-graded (not uniform size) to minimize voids — target ≤30% void ratio. Fill stones manually near the face for appearance and mechanically in the interior for efficiency. Each 1m³ compartment requires approximately 1.6-1.8 tonnes of stone. Fill in 300mm lifts, placing internal bracing wires (supplied) at each lift to prevent bulging. After filling, the lid is wired shut using lacing wire at 200mm intervals along all edges.
