Heavy-Duty Chain Link Fence — Galvanized + PVC Coating (Class 2b)
When clients come to get long-lasting and secure fencing solutions, choosing the right method of coating makes a lot of differences. At CFC Fencing, we provide high-performance chain link fences designed to withstand harsh environments while ensuring strength, durability, and protection. One of our most advanced options is the Galvanized chain link fence + PVC Coated Chain Link Fence (Class 2b), supported by profiled round posts for added stability.
🔹 What is Class 2b PVC Coating?
The classification actually comes from ASTM F668, which defines how PVC is applied to galvanized chain link fences.
- Class 1: PVC is extruded only (not bonded, lower durability).See this standard product.
- Class 2a: PVC is extruded and bonded to the wire (better adhesion).See this standard product.
- Class 2b: PVC is fused and bonded to the galvanized steel core, creating the strongest, most durable protection.See this standard product.
With Class 2b, the PVC layer is melted and chemically bonded into the galvanized surface. This ensures:
- Superior adhesion (it won’t peel or crack).
- Maximum resistance against rust, UV rays, and corrosion etc.
- Longer lifespan even in coastal, humid, or industrial areas especially.
🔹 GBW vs. Galvanized + PVC Coating (Class 2b)
Before deciding on your fence type, it’s important to understand the difference between GBW (only Galvanized Before Weaving chain link fence) and PVC-coated galvanized chain link fences:
| Feature | GBW – Galvanized Before Weaving | Galvanized + PVC Coating (Class 2b) |
|---|---|---|
| Zinc Coating | Heavy zinc layer applied before weaving, excellent standalone protection | Lighter zinc layer compared to GBW |
| PVC Layer | Not required due to heavy galvanization | Added Class 2b PVC fused and bonded layer for extra protection |
| Durability | Long-lasting due to heavy zinc | Extended lifespan thanks to dual-layer (zinc + PVC) |
| Look & Finish | Traditional silver galvanized finish | Available in green, black, and other colors for modern appearance |
| Best Use | Industrial, rural, or where heavy zinc protection alone is enough | Residential, commercial, coastal, or where extra corrosion/UV protection and aesthetics matter |
🔹 Why Choose Which?
- Choose only Galvanized Before Weaving (GBW) if you need a cost-effective, heavily galvanized fence with proven long-term resistance and do not require additional PVC coating.
- Choose Galvanized + PVC (Class 2b) if you prefer dual-layer protection with color options and need extra resistance in aggressive climates or want a more aesthetic finish.
✅ Conclusion
Both GBW and Galvanized + PVC Coated (Class 2b) fences offer outstanding durability. The choice depends on whether you prioritize the heavy zinc layer of GBW or the enhanced dual-layer protection and aesthetics of Class 2b PVC coating.
At CFC Fencing, we provide both options — each designed to deliver lasting performance with the strength and security you can trust.
