Chain link fence

Chain-Link Fence Specifications and Applications
Chain-link fences are versatile, cost-effective barriers made of interwoven steel wires, widely used for security, containment, and boundary marking. Below are their key specifications, materials, and applications:

1. Specifications

A. Material

Galvanized Steel: Most common; zinc-coated for rust resistance (Class 1–3, with Class 3 offering the highest corrosion protection).


Vinyl-Coated Steel: PVC-coated for added weather resistance and color options (e.g., black, green).


Stainless Steel: Used in coastal or highly corrosive environments.


Aluminum: Lightweight and rust-proof for low-security applications.


B. Gauge (Wire Thickness)

9 Gauge: 3.8 mm – Heavy-duty for high-security areas (e.g., prisons, industrial sites).


11 Gauge: 2.7 mm – Standard for residential and commercial use.


12 Gauge: 2.3 mm – Lightweight for temporary fencing.


C. Mesh Size

1" (25 mm): Small openings for small animal containment (e.g., dogs, poultry).


2" (50 mm): Standard size for general-purpose fencing.


3" (75 mm): Larger gaps for cost-effective boundary marking.


D. Height

Residential: 3–6 ft (0.9–1.8 m).


Commercial/Industrial: 6–12 ft (1.8–3.6 m).


High-Security: 12+ ft (3.6+ m) with barbed wire toppings.


E. Coating

Hot-Dip Galvanized: ≥245 g/m² zinc coating for durability.


PVC Coating: 0.5–1.0 mm thickness for UV and abrasion resistance.


F. Tensile Strength

Standard: 40,000–80,000 psi.


High-Tensile: Up to 100,000 psi for enhanced durability.


2. Components

Fabric: Interwoven diamond-pattern wire mesh.


Posts:


Terminal Posts: Corner/end posts (2.5–4" diameter steel or aluminum).


Line Posts: Intermediate supports (1.5–2.5" diameter).


Top Rail: Horizontal support (1–2" diameter).


Tension Wire: Secures the fabric to the posts.


Accessories:


Barbed Wire: Added to the top for security.


Privacy Slats: Inserted into the mesh for visual screening.


Gates: Swing or sliding options (match fence height/material).


3. Applications:

4. Installation

Post Spacing: 8–10 ft apart for line posts.


Concrete Footings: Required for terminal posts in permanent installations.


Anchoring: Use ground spikes or weighted bases for temporary setups.


5. Advantages

Cost-Effective: Cheaper than wood, wrought iron, or welded mesh.


Durability: Lasts 15–20+ years with galvanized/PVC coating.


Low Maintenance: Resists rot, pests, and weathering.


Visibility: Allows airflow and light while marking boundaries.


6. Limitations

Privacy: Requires slats or screens for visual obstruction.


Aesthetics: Less decorative than ornamental iron or wood.


Security: Easily cut without reinforced toppings (e.g., barbed wire).
