PVC Coated Chainlink Fencing: Complete Guide, Specs & Pricing

Quick Summary:

PVC Coated Chainlink combines a hot-dip galvanized steel core wire with an extruded polymer PVC coating. This dual-layer construction provides 100% rust-proof performance, making it ideal for high-humidity, agricultural, and coastal environments. Available in mesh apertures of 50x50mm, 65x65mm, and 80x80mm, inner wire gauges from 10G to 14G, and heights from 4ft to 10ft. Standard roll lengths are 18 metres (KEBS standard), with prices ranging from KSh 4,600 to KSh 29,700 per roll depending on height, mesh aperture, and core wire thickness.

1. Dual Corrosion Barrier:

   Standard galvanized chainlink relies solely on zinc plating. PVC coated chainlink applies a continuous, seamless polymer shell over hot-dip galvanized core wire. Even if the outer coating incurs surface scuffs, the underlying zinc layer prevents moisture penetration and rust migration.

2. UV & Coastal Atmospheric Resistance:

   Formulated with UV stabilizers, quality PVC coatings resist cracking, chalking, and peeling under intense sun exposure. It is specifically engineered for harsh environments like coastal areas (e.g., Mombasa, Malindi) where marine salt spray degrades un-coated steel within 2 to 3 years.

3. Aesthetic Landscape Integration:

   The rich dark green finish (standard color) blends into foliage, sports arenas, and landscaped lawns without the cold industrial appearance of unpainted steel wire.

4. Safety & Smooth Finishing:

   The flexible PVC coating buffers sharp wire burrs at knuckled ends, making it safer for sports courts, school grounds, and dog runs.

Frequently Asked Questions

Q1: Does the PVC coating peel or crack over time?

No. Quality PVC chainlink uses an extruded coating process where the high-density polymer bonds tightly over the galvanized wire. Formulated with UV inhibitors, it prevents peeling, sun-bleaching, and brittle cracking under hot climate conditions.

Q2: How do core wire gauges work for PVC chainlink?

Wire thickness is measured in two parts:

• Core Wire Gauge: The actual diameter of the galvanized steel wire inside (e.g., 2.0mm / 14G or 2.5mm / 12G).

• Overall Diameter (OD): The core thickness plus the PVC coating layer (typically adding 0.8mm–1.0mm).

  Always check the core wire thickness when comparing products to ensure structural strength.

Q3: What mesh opening (aperture) should I choose?

• 50x50mm (2 inches): Highest security level; prevents intruders or animals from getting footholds or reaching through.

• 65x65mm (2.5 inches): Standard balance between cost and perimeter security for residential property.

• 80x80mm (3 inches): Most economical option for long agricultural or boundary demarcation fencing.
