Wholesale Galvanized Chain Link Fence Roll

Product Overview

Galvanized chain link fence rolls are manufactured from low‑carbon steel wire that is woven into a diamond mesh and subsequently coated with a zinc layer to inhibit corrosion. The roll format allows continuous lengths to be cut on‑site, reducing joint count and installation time for perimeter security, sports enclosures, and agricultural barriers.

Typical wire diameters range from 2.0 mm to 4.0 mm, with mesh openings of 50 mm × 50 mm or 60 mm × 60 mm. The zinc coating weight is expressed in grams per square meter (g/m²) and directly influences service life in various environments.

Technical Specifications

Key parameters are defined by ASTM A392 (zinc‑coated steel chain-link fence fabric) and ISO 1461 (hot‑dip galvanizing). The following table lists typical values that can be adjusted according to project requirements.

Tensile strength of the base wire typically falls between 350 MPa and 550 MPa, depending on carbon content and drawing process. The zinc coating adds a sacrificial layer that corrodes preferentially, preserving the underlying steel.

Material Selection and Corrosion Performance

Low‑carbon steel (C ≤ 0.10 %) provides good ductility for weaving while maintaining sufficient strength. The hot‑dip galvanizing process immerses the woven fabric in molten zinc at approximately 450 °C, forming a metallurgical bond that resists peeling.

In neutral atmospheres, a 250 g/m² coating can deliver 12‑15 years of service before noticeable rust; in marine or industrial environments, the same coating may last 5‑8 years. For extended life, a heavier coating (up to 350 g/m²) or a dual‑layer (zinc‑aluminum) option is available upon request.

• Wire grade: ASTM A641 Class 1 soft temper
• Coating method: Hot‑dip galvanizing per ISO 1461
• Optional coating: Zn‑Al alloy (5% Al) for enhanced durability

Applications and Installation Benefits

The continuous roll format reduces the number of splices, which are common points of weakness in fence systems. This is particularly advantageous for long perimeters such as airport boundaries, railway rights‑of‑way, and agricultural fields where uniform tension is required.

Sports facilities benefit from the uniform mesh opening, which provides consistent ball rebound characteristics while maintaining visibility. The lightweight nature of the rolls facilitates rapid deployment for temporary event barriers or construction site enclosures.

When installed with tension bands, brace rails, and proper post spacing (typically 2.5 m to 3.0 m), the fence can withstand wind loads of up to 150 km/h without excessive deflection, depending on post embedment and foundation type.

Quality Control and Testing

Each production lot undergoes dimensional verification, coating weight measurement, and tensile testing. Coating weight is verified using the gravimetric method per ASTM A90, ensuring compliance with the specified g/m² range.

Visual inspection checks for uniform zinc coverage, absence of bare spots, and proper mesh integrity. Mechanical properties are confirmed by pulling a wire sample to failure and recording the ultimate tensile strength.

• Diameter tolerance: ±0.05 mm
• Mesh opening tolerance: ±2 mm
• Coating weight tolerance: ±10 g/m²
• Visual defect limit: <0.5 % of surface area

Packaging and Logistics

Rolls are wound onto a sturdy cardboard or plastic core, then wrapped in UV‑stabilized polyethylene film to protect against moisture and abrasion during transit. The outer layer is secured with polyester strapping.

Standard pallet configuration holds 16 rolls (assuming 1.2 m width × 25 m length) with a total weight not exceeding 1,200 kg, facilitating forklift handling. Custom packaging, such as waterproof crates or container‑specific pallets, can be arranged based on destination requirements.
