Hot-Dipped Galvanized: Properly cleaned steel wire is immersed in molten zinc, forming a zinc-alloy layer and a pure zinc layer on its surface. A higher zinc coating weight results in stronger corrosion resistance and a longer service life. While standard galvanizing may have a low coating weight of 40-60 g/m², high-quality gabion mesh requires a minimum zinc coating of 200-260 g/m².

Galfan (Zinc-Aluminum Alloy): Properly cleaned steel wire is immersed in a molten zinc bath containing 5% or 10% aluminum, along with trace rare earth elements. This alloy offers 2-3 times the corrosion resistance of pure hot-dipped galvanizing at an equivalent coating weight. The addition of aluminum promotes the formation of a denser, more stable protective layer.

PVC/PE Coating: A layer of PVC (Polyvinyl Chloride) or PE (Polyethylene) plastic sheath is extruded over a core wire of hot-dipped galvanized or Galfan steel. This provides an additional protective barrier and allows for color customization.
