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:
- Product Details
- Technical Specification
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).
