PVC vs. Galvanized Wire Gabions: Which is More Durable?

In construction, especially when solutions are needed for erosion control, soil retention, embankments, or slope and river protection projects, the choice of gabion type significantly determines its lifespan. Two common options on the market are gabions made with galvanized wire and gabions made with PVC-coated wire. Each has its own characteristics.

What Are PVC Gabions and Galvanized Gabions?
Galvanized Gabions: These use zinc-coated steel wire, providing better corrosion protection than plain steel. This wire is then woven into a "basket" filled with rocks or gravel to form a retaining structure.

PVC Gabions: These are essentially steel wire (often pre-galvanized), with a polymer coating—PVC (polyvinyl chloride)—added for added protection. This PVC coating encases the wire, providing extra protection against corrosion, abrasion, UV rays, and humid or aggressive environmental conditions (e.g., acidic soil, saltwater, pollution).

Pros & Cons: PVC vs. Galvanized

Aspect	Galvanized Wire Gabion	PVC-Coated Wire Gabion
Corrosion & rust resistance	Good in normal environments; zinc coating protects from mild oxidation.	Higher corrosion resistance, especially in humid, acidic, or coastal environments. PVC + galvanizing provides double protection.
Lifespan & durability	Typically long-lasting under ideal / non-aggressive conditions.	Longer lifespan in harsh environments — PVC gabions often outperform regular galvanized ones.
Resistance to abrasion, weather, UV & saltwater	More vulnerable when exposed to rain, moisture, or acidic/salty conditions — zinc layer may wear out.	PVC coating adds protection against weather, abrasion, UV exposure, and saltwater corrosion.
Appearance & aesthetics	Metallic grey look, limited visual options.	Available in colors (depending on PVC coating), more visually appealing and blends with landscaping.
Cost & availability	Cheaper and widely available.	Slightly more expensive due to added PVC coating and complex production.

When Should You Choose PVC — and When Is Galvanized Enough?

• Choose PVC Gabions if:
  • The project is in a humid environment, near rivers, the ocean, or an area with potential saltwater/pollution.
  • Long service life and maximum durability are required.
  • Aesthetic results are desired (color can be customized).
  • The structure will be in contact with water, extreme weather, or damp/acidic soil.
• Choose Galvanized Gabions if:
  • The project is in a dry area, under normal conditions, not exposed to saltwater or heavy pollution.
  • The budget is limited and the structure's function is relatively simple.
  • No special aesthetics are required — functionality and cost are more important.

Conclusion: Which is More Durable?

In general, gabions with PVC-coated wire tend to be more durable and long-lasting than regular galvanized gabions — especially when used in humid, high-temperature environments, near water, or corrosive conditions. The PVC and galvanized coating provides double protection against corrosion, abrasion, and environmental influences, extending the structure's lifespan.

However, if your project is in a normal, non-extreme environment — and cost is a priority — galvanized gabions can still be a good choice.
