Chain link fence systems remain one of the most practical and affordable choices for homeowners in the Pacific Northwest. They are durable, easy to maintain, and versatile. But choosing the right materials for chain link fence projects is what really determines whether your fence will last for decades or start to sag and rust in just a few years. The strength of the chain link fabric, the type of line posts and terminal post, the quality of the tension wire and chain link fittings, and even the little details like tension bands and carriage bolts all add up to the difference between a solid, secure installation and a fence that becomes a headache.
In this guide, we will walk through all the parts of a chain link fence, explain how the different materials work together, and give practical tips on what to choose for your home. Whether you are comparing galvanized fence fabric with vinyl-coated chain link, trying to understand which tension bar you need, or planning the post spacing with a post hole digger, you will come away knowing how to make smart, long-term decisions for your fence.
The Core Parts of a Chain Link Fence
Every chain link fence system includes more than just the wire mesh. The full system has posts, rails, hardware, and coatings that work together to secure the fabric at the right tension. Understanding all the parts will help you plan your project.
Chain Link Fabric: The Backbone of the Fence
The chain link fabric is the woven wire mesh that forms the actual barrier. This woven material comes in rolls of different heights and gauge thicknesses. The correct height of your fabric depends on whether you are keeping pets in, deterring intruders, or just marking a property line.
- Gauge: The lower the number, the thicker the wire. For example, 11-gauge is common for residential use, while 9-gauge is stronger and typically used for commercial properties. Heavy-duty 6-gauge fabric is often seen in high-security or industrial locations.
- Mesh Size: Standard fabric has 2-inch diamond openings. Smaller openings, like 1-inch mini-mesh, provide added security and are harder for pets or intruders to climb.
- Coatings: You can choose galvanized steel, aluminized, or vinyl-coated chain link fabric. Coatings help protect the steel from corrosion, especially near wet ground or in salty coastal climates.
When installing, you will usually roll out the first row of fabric, attach it to a tension bar, and use fence ties or hog rings to fasten it to the line posts.
Line Posts, Terminal Post, and Corner Posts
Posts are the vertical supports that carry the load of the fence. Without sturdy posts set at the right depth, even the strongest fence fabric will sag.
- Line Posts: These are the smaller posts that run between the end supports. Good post spacing is usually 6 to 10 feet, depending on the gauge of the fabric and the height of the fence.
- Terminal Post: Heavier posts set at the ends, corners, and gate post locations. These take the most stress from the stretched tension wire and tension bar.
- Corner Posts: Extra-strong posts set at fence corners, since the fabric pulls in more than one direction.
- End Post: Similar to a terminal, placed at the end of a fence line where no turn occurs.
Posts are set in concrete below ground level to keep them stable. The hole depth depends on fence height, but a good rule is to dig holes at least one-third the height of the post. For example, a 6-foot fence needs posts buried at least 2 feet deep. Using a post hole digger makes this job easier.
Each post is finished with a post cap to keep water out and protect the post from rusting.
Top Rail and Rail Hardware
The top rail runs horizontally along the top of the posts, giving the fence its shape and preventing sag. The rail end and rail end band attach the top rail to the terminal post. A line post top fitting allows the rail to slide through and connect across the line posts.
The bottom of the fence can either use a tension wire or a bottom rail. A tension wire runs along the ground line, pulling the fabric tight and keeping pets from pushing under. For extra rigidity, some homeowners choose a bottom rail, but this adds cost.
Fence Ties, Tension Bands, and Other Chain Link Fittings
Chain link fittings are the smaller pieces that often get overlooked but are essential for a proper installation.
- Fence Ties: Small pieces of wire that attach the chain link fabric to the line posts and top rail.
- Tension Bands: Metal bands that wrap around a terminal post, holding the tension bar that secures the fabric edge.
- Brace Bands: Used with a rail end to connect horizontal bracing to a terminal post.
- Tension Bar: A steel bar woven into the edge of the fabric to distribute pulling force evenly across the tension bands.
- Carriage Bolts: Bolts that fasten fittings like brace bands and tension bands to posts. They have a smooth head that prevents tampering.
Even the gate frame uses special fittings to connect the hinges, bolts, and posts. Getting the right set of chain link fittings ensures the fence stays tight and resists sagging.
Choosing the Right Materials for Chain Link Fence Projects
Every homeowner wants a fence that balances cost, durability, and looks. Here is how the major material choices compare.
Galvanized Steel Chain Link Fabric
- Most common and affordable
- Wire coated with zinc to resist rust
- Typically lasts 15 to 20 years with good installation
- Best for budget-friendly projects
Vinyl-Coated Chain Link Fabric
- Starts with galvanized wire, then adds a vinyl or polymer jacket
- Comes in black, green, or brown, making it blend better with landscaping
- Protects against corrosion and UV damage
- Typically lasts 20 to 30+ years
- Popular in neighborhoods with HOAs or design restrictions
Aluminized Chain Link Fabric
- Steel wire coated with aluminum instead of zinc
- Excellent for coastal or industrial locations where salt or chemicals accelerate corrosion
- Costs more than galvanized but offers long-term value
Other Material Options
- Composite coatings for extreme environments
- Recycled steel for eco-friendly builds
- Specialized fabrics designed for insert privacy slats or wind screens
Wire Gauge and Fabric Size
The gauge of your chain link fabric and the size of the mesh openings will directly affect the fence’s strength.
- 11-gauge: Standard for homes
- 9-gauge: Heavier duty, better for larger pets or high-use areas
- 6-gauge: Industrial-level strength
- Mesh Size: Standard 2-inch, smaller openings for extra security
How to Install with the Right Materials
A solid chain link fence depends not only on choosing the right materials but also on installing them properly.
- Mark your fence line with string and stakes. This helps you measure the exact length and plan post spacing.
- Dig holes for the line posts, corner posts, and terminal post with a post hole digger. Set them in concrete, keeping everything level and aligned.
- Add post caps to prevent water damage.
- Attach the top rail with rail ends and brace bands, then add a tension wire at the bottom near ground level.
- Roll out the fabric, weave in the tension bar, and connect it to the tension bands on the end post or gate post.
- Pull the fabric tight, adjust for slope if needed, then use fence ties to secure the mesh to each line post and the top rail.
- Trim any excess fabric with bolt cutters, making sure the edges are safe.
- Install the gate frame with proper hinges and carriage bolts, making sure it swings in the right direction and clears the ground.
This sequence creates a fence that is tight, aligned, and strong. A common mistake is leaving the mesh too loose, which causes sagging and early wear. Another is forgetting to tighten the tension wire, which can lead to gaps at the bottom.
