Surface Treatments Of Barbed wire
Galvanization – The fundamental corrosion protection.
Electro-Galvanizing: Produces a smooth, bright white surface with a relatively thin zinc layer. Offers basic corrosion resistance, suitable for indoor or dry environments. A cost-effective option.
Hot-Dip Galvanizing: This is the industry standard. The wire is immersed in a ~450°C molten zinc bath, forming a thick, protective coating with a characteristic spangled pattern. Provides superior protection for 10-20 years. We clearly specify the zinc coating weight (e.g., 60g/m², 80g/m²) for transparent customer comparison.
PVC/PE Coating (Plastic Dip)
Process: A layer of durable plastic is fused onto a hot-dip galvanized wire base via electrostatic application or high-temperature melting.
Performance Leap: The plastic layer creates a complete barrier against air and moisture, exponentially increasing corrosion resistance. The flexible coating also cushions physical impacts, protecting the underlying zinc layer from damage.
Galfan (Zinc-Aluminum Alloy) Coating – A premium choice.
Introduction: A zinc-aluminum alloy coating (typically containing 5% or 10% Aluminum). Its corrosion resistance is 2-3 times greater than standard hot-dip galvanizing, performing exceptionally well in harsh industrial and coastal environments. Although higher in cost, it is the optimal choice for clients requiring maximum service life.
