Chain link is the most versatile fencing material in the industry. It serves residential backyards, commercial perimeters, industrial facilities, sports complexes, and everything in between. The AFA's Fence Installation School devotes an entire discipline to chain link installation — covering framework, fabric stretching, splicing, gates, and barbed wire — more technical depth than any other fence type.
Here's what homeowners, contractors, and property managers need to know.
Why Chain Link?
Chain link offers advantages that no other fence material matches:
- Lowest cost per foot of any permanent fencing: $15–$35/ft installed
- Longest lifespan for the price: 20–30+ years with galvanized coating
- Transparent: doesn't block views, light, or airflow
- Modular: easy to extend, modify, or repair
- Strong: per ASTM F567-07, chain link fabric provides effective security at a fraction of the cost of solid alternatives
The tradeoff is obvious: chain link provides no privacy (unless you add slats), and it doesn't win aesthetic awards.
Chain Link Components
Per the AFA's chain link discipline, a chain link fence system includes:
Framework:
- Posts: Line posts (every 10 feet for residential), terminal posts (ends, corners, gate openings)
- Top rail: Continuous pipe connecting all line posts, inserted through loop caps
- Brace assemblies: Diagonal braces at terminal posts to resist fabric tension
Fabric:
- Chain link mesh: Woven wire in a diamond pattern. The gauge (thickness) and mesh size determine strength.
- Tension wire: Bottom wire that anchors the fabric and prevents animals from pushing underneath
- Tension bands and bars: Hardware that secures fabric to terminal posts
Accessories:
- Barbed wire arms and wire: Top-mounted security addition for commercial/industrial
- Privacy slats: Inserted into mesh for visual screening
- Windscreen: Attached fabric that reduces wind and provides partial privacy
Wire Gauge: The Most Important Specification
The gauge of the chain link fabric determines its strength, durability, and cost. Lower gauge number = thicker wire = stronger fence.
| Gauge | Wire Diameter | Application | Cost Impact |
|---|---|---|---|
| 6 gauge | 0.192" | Heavy industrial, high-security | Highest |
| 9 gauge | 0.148" | Standard commercial/residential | Standard |
| 11 gauge | 0.120" | Light residential, temporary | Lower |
| 11.5 gauge | 0.113" | Economy residential | Lowest |
For a detailed breakdown of gauge specifications and when to use each, see our chain link gauge guide.
Our recommendation: 9 gauge for any permanent installation. 11 or 11.5 gauge is adequate for temporary or low-security applications, but it dents more easily and has a shorter lifespan. Chicago, Cleveland, and other Midwest markets typically default to 9 gauge for residential.
Coatings
Chain link fabric comes in three primary coatings:
- Galvanized (zinc-coated): The standard. Prevents rust for 15–25 years depending on climate. Galvanized before weaving (GBW) or galvanized after weaving (GAW) — GAW provides better protection at joints.
- Vinyl-coated (PVC): Galvanized core with colored vinyl coating. Available in black, green, brown, and white. More attractive, longer-lasting, but 30–50% more expensive.
- Aluminum-coated (aluminized): Excellent corrosion resistance for coastal and industrial environments. Less common than galvanized.
Chain Link Fence Costs
| Type | Installed Cost Per Foot |
|---|---|
| 4 ft residential (11 gauge) | $15–$22 |
| 4 ft residential (9 gauge) | $18–$28 |
| 6 ft residential (9 gauge) | $22–$35 |
| 6 ft commercial (9 gauge) | $28–$40 |
| 6 ft with privacy slats | $28–$42 |
| 8 ft commercial | $32–$48 |
| Vinyl-coated (black, 6 ft) | $28–$42 |

Installation Overview
The AFA's chain link installation sequence:
1. Layout and Post Setting
Mark the fence line and set terminal posts first (ends, corners, gate posts), then fill in line posts at 10-foot intervals. Per ASTM F567-07, line post spacing for residential chain link is 10 feet on center. Commercial and industrial may use 8-foot spacing for added strength.
Posts should be set in concrete per the AFA's post setting standards — see our post depth guide and concrete footings guide for specifications.
2. Install Framework
Attach top rail through loop caps on line posts. Connect rail sections by sliding the swedge (tapered) end into the non-swedge end. Install brace assemblies at all terminal posts — the diagonal brace resists the tension that pulling chain link fabric places on the end posts.
3. Stretch and Attach Fabric
This is the most technically demanding step. Per the AFA training:
- Unroll fabric on the ground along the fence line
- Attach to one terminal post using tension bars and bands
- Use a come-along or fence stretcher to pull fabric tight to the opposite terminal post
- Secure with tension bars and bands at the other end
- Tie fabric to top rail and line posts using aluminum or galvanized ties
Proper tension is critical. Too loose and the fabric sags, creating an unprofessional appearance and reducing security. Too tight and it puts excessive stress on terminal posts, potentially pulling them out of alignment. The AFA training covers stretching in detail, noting that installers must pay attention to tension on the mesh — it can snag on ground or framework, and untied mesh can fall over.
4. Bottom Tension Wire
Run a tension wire along the bottom of the fabric and secure to terminal posts. This prevents the bottom edge from being lifted — important for pet containment and security.
5. Barbed Wire (Commercial/Industrial)
For commercial applications, barbed wire arms mount to the top of terminal and line posts. Three strands of barbed wire is standard. The AFA covers barbed wire installation as a separate procedure within the chain link discipline.
Note: Barbed wire is prohibited on residential fences in most municipalities. Check local codes.
Chain Link Gates
Chain link gates come in three primary types:
- Swing gates: Single or double, most common for residential and commercial walk-through and vehicle access
- Rolling gates: Slide horizontally on a track, used for wide openings (typically 20+ feet)
- Cantilever gates: Slide without a track, supported by rollers on the gate post assembly
The AFA's gate hardware section covers hinges, latches, drop rods, gate wheels, and keepers in detail. Proper gate post sizing is critical — gate posts carry more stress than any other post in the fence.
Frequently Asked Questions
How long does chain link fence last?
Galvanized chain link lasts 20–25 years in most climates. Vinyl-coated chain link lasts 25–30+ years. The framework (posts and rail) typically outlasts the fabric.
Can chain link be made private?
Yes, with privacy slats (inserted into the mesh diamond pattern), windscreen, or hedge plantings. Slats add $4–$7/ft and come in various colors.
Is chain link good for dogs?
It's excellent for dog containment — strong, see-through (dogs can see out, reducing barking), and difficult to dig under with a bottom tension wire. Use 9-gauge minimum for large dogs.
Does chain link rust?
Galvanized chain link resists rust for 15–25 years. After the zinc coating wears, rust begins. Vinyl-coated chain link adds a second protective layer and lasts longer. In coastal areas like Tampa, vinyl-coated or aluminized chain link is recommended.
