Surface treatment guide
A practical coating guide for outdoor wire mesh fence projects comparing galvanized, powder coated and PVC coated options.
Quick answer
Surface treatment should be selected by service environment, target life, appearance requirement, budget and local specification. Buyers should confirm zinc layer, powder or PVC coating, color, salt exposure and inspection requirements before comparing quotations.

Use these points to compare suppliers and send an RFQ with enough information for a useful reply.
Dry inland sites, humid areas, coastal environments and industrial zones may need different anti-corrosion levels.
Two suppliers can quote the same color but use different substrate and coating thickness.
Rigid panels, chain link rolls, farm fence and razor wire use different coating logic.
Quotation data
| Treatment | Best For | Buyer Check |
|---|---|---|
| Galvanized | Economical outdoor fence and roll products | Zinc layer, wire diameter and post coating |

| PVC coated | Chain link fence and selected outdoor systems | Core wire diameter, coated diameter and color |
| Duplex system | Higher corrosion requirement projects | Galvanizing plus powder or PVC coating sequence |
| Coastal projects | Humid or salt exposure areas | Higher anti-corrosion requirement and inspection photos |

They serve different roles. Galvanizing protects steel against corrosion, while powder coating improves appearance and adds another protective surface. Many welded panels use both.
PVC-coated chain link uses a steel wire core with an outer PVC layer. Buyers should confirm both core wire diameter and coated diameter.
