Durable Metal Wire Fence – Technical Overview

Metal wire fences serve as structural barriers that combine tensile load capacity with corrosion resistance to delineate perimeters, contain livestock, and protect infrastructure.

Material and Construction

The core material is low-carbon steel wire with a typical carbon content of 0.10%–0.20%, providing a balance between ductility and strength. Wire is hot-dip galvanized to a coating mass of approximately 270 g/m² (equivalent to ~20 µm zinc thickness) or optionally coated with a 0.5 mm PVC layer for enhanced UV and chemical resistance.

Design Parameters

Tensile strength of the wire ranges from 450 MPa to 550 MPa, with elongation at break between 10% and 18%. Mesh openings are available in square or rectangular configurations, common sizes include 50 mm × 50 mm, 75 mm × 100 mm, and 100 mm × 100 mm. Wire diameter options span 2.0 mm, 2.5 mm, 3.0 mm, and 4.0 mm, allowing adjustment of panel stiffness and impact resistance.

Applications

In agricultural settings, the fence functions as a livestock barrier that withstands animal impact while resisting rust from soil moisture and fertilizers.

• Cattle and sheep enclosures – wire diameter 3.0 mm–4.0 mm with 50 mm square mesh prevents hoof penetration.
• Poultry runs – smaller 25 mm×25 mm mesh with 2.0 mm wire protects against predators while allowing ventilation.
• Industrial perimeter security – 3.0 mm wire, 75 mm×100 mm mesh, optional PVC coating provides climb resistance and durability against mechanical impact.
• Wildlife control areas – 1.8 mm–2.5 mm wire with 30 mm×30 mm mesh prevents entry of small mammals while maintaining visibility.

Customization Options

Depending on site conditions, wire diameter can be selected to match expected load, while mesh size is adjusted to control passage of specific animals or debris. Height of the fence panel is typically supplied in rolls of 1.0 m, 1.5 m, or 2.0 m, and can be slit to custom lengths on‑site. Coating choice (galvanized only, galvanized + PVC, or powder‑coated) is determined by exposure to UV, salt spray, or chemical environments.

Quality Control and Testing

Quality assurance incorporates dimensional checks of wire diameter and mesh pitch using laser micrometers, tensile testing of specimens per ASTM A370, and coating thickness measurement via magnetic inductance. Corrosion resistance is validated by salt‑spray exposure (ASTM B117) for 500 hours with acceptance criteria of less than 5% red rust.

Packaging and Logistics

Finished rolls are packaged to protect against deformation and corrosion during transit. Each roll averages 50 kg, is wrapped in shrink‑film, placed on a pallet with corner protectors, and secured with poly‑straps. A standard 20‑ft container holds approximately 22 pallets, facilitating efficient overseas shipment.
