Chain Link Fence Spec Guide: Gauge, Material, Mesh & Coating Decoded

Chain link (cyclone fence) dominates utilitarian fencing. Spec choices determine security level, lifespan, and cost.

1. Wire Gauge (Thickness)

• 6 ga (0.192"): Industrial/security. Highest cost.
• 9 ga (0.148"): Residential standard. Balance.
• 11-11.5 ga: Light commercial.
• 13 ga (0.091"): Temporary/event. Lowest cost.

Lower number = thicker wire = stronger, heavier, pricier.

2. Base Metal

• Galvanized steel: Zinc-coated. Standard. Requires tension wire maintenance.
• Aluminum: Lighter, no rust, easier install. Lower tensile strength. Premium cost.

3. Mesh Size (Diamond Opening)

• 2" (50mm): Standard. Good visibility/airflow.
• 1.75" (44mm): Higher security. More steel per foot.
• 1" (25mm): Mini-mesh. Maximum climb resistance. Prison-grade.

4. Coating Systems

• Galvanized only: Silver, 15-20 yr rural, 10-15 yr coastal.
• PVC/vinyl coated: Black, green, brown. Adds 5-10 yr life. UV inhibitors critical.
• Polyester powder: Thicker, harder, best color retention. Premium.

Height Standards

3-4 ft: Residential boundary.
5-6 ft: Pet containment, light security.
8-10 ft: Commercial/industrial.
12 ft: High-security, athletic facilities.

Match spec to threat level. Over-spec wastes budget; under-spec fails.
