Green PVC Vinyl Coated Chain Link Fence – Manufacturer Overview

The fence core is made from low‑carbon steel wire that undergoes hot‑dip galvanizing to achieve a zinc coating weight of typically 180 g/m². A PVC vinyl layer is then extruded over the galvanized wire, resulting in a total coating thickness of 0.5 mm to 0.8 mm depending on customer specifications.

Material Composition and Coating Process

Galvanization provides sacrificial protection against rust, while the PVC vinyl acts as a barrier to moisture and chemicals. The vinyl formulation includes titanium dioxide for UV resistance and a green pigment dispersed at a concentration that ensures color stability under ASTM G154 cyclic UV exposure.

Engineering Specifications

Property	Typical Value	Unit	Notes
Wire diameter (core)	2.0 – 3.5	mm	Galvanized before coating
Mesh opening	50 × 50	mm	Standard square mesh
Roll height	0.9 – 3.0	m	Custom heights available
Tensile strength of wire	≥ 350	MPa	Measured per ASTM A370
PVC coating thickness	0.5 – 0.8	mm	Uniform over entire wire
Coating adhesion	≥ 12	N/mm	Peel test per ASTM D903

Performance Characteristics

The combination of galvanized steel and PVC vinyl yields a corrosion resistance rating suitable for environments with up to 5 % chloride exposure, as demonstrated by 1000‑hour salt spray testing (ASTM B117) with less than 5 % red rust appearance. The coated fence retains flexibility down to ‑30 °C, allowing installation in cold climates without cracking.

Impact resistance is measured by a falling weight test; a 1 kg steel ball dropped from 1 m produces no coating delamination or wire breakage. The PVC layer also provides electrical insulation, with a volume resistivity exceeding 10¹² Ω·cm.

Typical Applications

• Agricultural livestock enclosures – the smooth vinyl surface reduces injury to animals while the coating resists fertilizer and manure corrosion.
• Sports field perimeter – non‑reflective green color minimizes visual glare for players and spectators.
• Construction site security – high tensile strength and optional barbed wire top deter unauthorized entry.
• Park and recreation barriers – UV‑stabilized color maintains appearance over years of sunlight exposure.
• Industrial facility boundaries – chemical‑resistant coating protects against splashes of oils and solvents.

Customization Options

• Wire gauge: 1.8 mm to 4.0 mm (core) to adjust load‑bearing capacity.
• Mesh size: 25 mm, 50 mm, 75 mm, or rectangular patterns for specific containment needs.
• Height: 0.6 m to 4.0 m, with optional overlap for seamless installation.
• Roll length: 10 m to 50 m, tailored to site logistics.
• Coating color: standard green, black, white, or custom RAL matches upon request.
• Additives: anti‑static, fire‑retardant, or antimicrobial agents can be incorporated into the PVC formulation.

Quality Assurance

In‑line monitoring includes laser micrometers for wire diameter, X‑ray fluorescence for zinc coating weight, and ultrasonic gauges for PVC thickness. Each batch undergoes adhesion testing, and a random sample is subjected to 500‑hour UV exposure followed by visual inspection for chalking or cracking.

Dimensional tolerances are held to ± 2 % for mesh opening and ± 0.1 mm for wire diameter, ensuring consistent tension when the fence is stretched.

Packaging and Shipping

Finished rolls are wrapped in low‑density polyethylene film to prevent surface abrasion, then placed on wooden pallets with corner protectors. Pallets are strapped with polyester bands and loaded into 20‑foot or 40‑foot containers with moisture‑absorbent desiccants.

Packaging Parameter	Typical Value	Unit
Roll weight (average)	15 – 25	kg
Pallet dimensions	1.1 × 1.1 × 0.9	m
Maximum rolls per pallet	20	units
Container load (20 ft)	16 – 18	pallets
