Direct Factory PVC Coated Chain Link Mesh

Product Overview

PVC coated chain link mesh is produced by extruding a polyvinyl chloride layer over a pre‑galvanized steel wire core directly in the factory, ensuring uniform coating thickness and eliminating variability introduced by secondary processing.

The steel core undergoes hot‑dip zinc plating before coating, providing a dual‑layer barrier against moisture and mechanical damage.

Core Wire Specifications

Base wire diameters range from 2.0 mm to 4.0 mm, selected according to required tensile strength and mesh rigidity.

Typical tensile strength of the galvanized core is 550 MPa, with a yield point around 450 MPa, allowing the mesh to withstand substantial impact loads without permanent deformation.

PVC Coating Characteristics

Coating thickness is maintained between 0.4 mm and 0.6 mm, measured by non‑contact laser gauges during extrusion.

The PVC formulation includes UV stabilizers and anti‑oxidants, granting a minimum 5‑year outdoor color stability under direct sunlight.

Available colors include standard green, black, and custom RAL matches upon request.

Mechanical Performance

Break load of the finished mesh varies with wire diameter; a 3.0 mm wire with PVC coating typically sustains 1.8 kN per lineal meter before failure.

Elongation at break remains under 15 %, ensuring the mesh retains its opening geometry under tension.

Flexural stiffness is sufficient to resist sagging in spans up to 3.0 m when installed with standard tension wires.

Corrosion Protection Mechanism

The zinc layer provides sacrificial protection, while the PVC coating acts as a physical barrier that limits chloride and oxygen ingress.

Combined, the system reduces corrosion rate to less than 5 µm/year in moderate industrial atmospheres, significantly extending service life compared to uncoated or solely galvanized mesh.

Typical Applications

Perimeter security for warehouses and manufacturing plants benefits from the mesh’s high tensile strength and low maintenance coating, deterring climbing and cutting attempts.

Animal enclosures utilize the smooth PVC surface to reduce abrasion on livestock hides while providing a durable barrier against weather.

Sports facilities select the product for its consistent aperture size, which ensures uniform ball rebound and visibility, and the coating’s resistance to chlorine‑based pool environments.

Industrial partitioning relies on the mesh’s fire‑retardant PVC grades (available on request) to meet local safety regulations without sacrificing visibility.

Quality Assurance

In‑line monitoring checks coating thickness every 2 m of production, with statistical process control keeping variation under ±0.05 mm.

Adhesion is evaluated by cross‑hatch tape testing per ASTM D3359, requiring a minimum rating of 4B before shipment.

Each roll undergoes visual inspection for pinholes, bubbles, or color inconsistencies, and a random sample is subjected to salt‑spray exposure (ASTM B117) for 500 h to validate corrosion resistance.

Customization Options

Wire diameter can be adjusted from 2.0 mm to 4.0 mm in 0.2 mm increments to match load requirements.

Mesh aperture (opening) ranges from 30 mm × 30 mm to 100 mm × 100 mm, affecting both security level and material cost.

Roll height is available from 0.9 m to 3.0 m, while standard roll lengths are 25 m or 50 m, with custom lengths possible upon agreement.

Color options extend beyond stock shades to any RAL or Pantone reference, subject to minimum order quantities.

Packaging and Logistics

Mesh is wound onto sturdy cardboard or plastic cores with an inner diameter of 50 mm, preventing deformation during transit.

Each roll is wrapped in UV‑stable stretch film and placed on pallets secured with strapping, optimizing container utilization.

Standard pallet dimensions accommodate 20‑ft and 40‑ft containers, with typical gross weight per pallet ranging from 800 kg to 1200 kg depending on wire size and roll length.

Frequently Asked Questions

• Can the wire diameter and coating thickness be tailored to specific project loads?
  Yes, both parameters are adjustable within the ranges noted above; technical drawings are required for quotation.
• What information is needed to receive a formal quote?
  Required details include desired wire diameter, mesh opening, roll height, length, color, and delivery destination.
• How is the PVC coating inspected for uniformity?
  Laser thickness gauges provide real‑time data, and periodic manual measurements verify compliance with ±0.05 mm tolerance.
• What packaging methods protect the mesh during overseas shipment?
  Rolls are film‑wrapped, palletized, and strapped; optional corner boards and moisture‑barrier sheets are available for high‑humidity routes.
