Chain-link fences are everywhere—lining backyards, parks, and job sites. Their simple, see-through design has been a practical choice for generations. But have you ever wondered what they're actually made of, and how they manage to last for decades?
In This Guide:
A Brief History
The chain-link fence traces its origins back to 1844 in Norwich, UK, first commercially produced by the firm Barnard, Bishop, and Barnard. Perhaps the most interesting part is its unexpected connection to the textile industry. The machine that weaves steel wire into its well-known diamond pattern was directly inspired by cloth-weaving technology.
What a Chain-Link Fence Is Made Of
A chain-link fence system has two main parts: the fabric (the mesh itself) and the framework that supports it. Let's break down the materials for each.
The Fence Fabric (Mesh)
The iconic diamond pattern of a chain-link fence is called the fabric or mesh. Essentially, it's made from steel wire that is coated for protection against weather and rust. There are two primary options:
Galvanized Steel This is the industry standard, giving the fence its classic silver-gray finish. The steel wire is coated in a layer of zinc. This protective zinc layer is designed to corrode first, shielding the steel underneath from rust. It's a simple, effective process that results in a durable and affordable fence.
PVC-Coated Steel For maximum protection and a touch of color, you can choose PVC-coated wire. This option offers a dual-layer defense: the steel wire is first galvanized and then covered in a thick layer of plastic (PVC). This completely seals the wire from moisture. The PVC coating also adds color, with black and green being popular choices that help the fence blend into its surroundings.
The Framework (Posts and Rails)
The framework is the structural support that holds the fence fabric in place. It includes all the posts, rails, and fittings. While steel is the most popular choice, other materials are available to suit your budget and the look you want to achieve.
Steel Posts Tubular steel posts are the most common and cost-effective option. They are typically galvanized or PVC-coated to match the fence mesh, ensuring a uniform look and lasting durability.
Timber Posts For a warmer, more natural appearance, chain-link mesh can be installed on timber posts. This combination works well in gardens or rustic settings. However, it's crucial that the wood is properly treated to resist rot and insect damage.
Concrete Posts When ultimate strength and longevity are the top priorities, concrete posts are the clear winner. They are completely unaffected by rot and rust and can withstand harsh weather and impacts, making them ideal for security or heavy-duty commercial applications.
How It's Made: From Wire to Woven Mesh
Here’s how automated machines weave simple wire into finished chain-link fabric:
Spiraling the Wire: A machine instantly twists a single strand of steel wire into a continuous, flat spiral.
Weaving the Mesh: This new spiral is immediately woven through the previous one, interlocking them to create the iconic diamond pattern.
Forming the Roll: This process repeats flawlessly, forming the mesh into a large, seamless roll of fabric ready for installation.
Finishing the Edges: Finally, the top and bottom edges are finished for either safety or security:
Knuckled: Wire ends are bent over to create a smooth, safe edge.
Barbed: Wire ends are twisted together into sharp points for higher security.
Material Advantages
The materials used give the fence its core strengths:
Lasting & Low-Care: Galvanized and PVC-coated steel is built to resist rust over 8 years, requiring little to no maintenance.
Cost-Effective: Simple materials and efficient production make it one of the most low-cost fencing options.
Reliable Security: The interlocking steel wire creates a strong, dependable barrier.
Conclusion
Now that you know the materials, you're ready to make a great choice. Just think about your budget, local weather, and the style you want to find the perfect materials and coatings for your project.
Frequently Asked Questions (FAQ)
When was the chain-link fence invented?
The chain-link fence was invented by Charles Barnard in Norwich, England, back in 1844. He was inspired by cloth-weaving machines to create the wire-weaving process that is still used today.
What material are chain-link fences made of?
A chain-link fence is made of strong steel wire. To protect it from rust, the steel is then covered in a protective layer—either a zinc coating (galvanized) or a colorful PVC vinyl coating.
Galvanized vs. PVC: Which is better?
It depends on your goals. Galvanized is the tough, budget-friendly classic that works great for most places. Choose PVC for maximum rust protection in coastal areas or if you want a specific color to match your home.
How long does a chain-link fence last?
A standard galvanized fence will easily last 5-10 years, while a PVC-coated one can last over 15 years. The final lifespan depends on the quality of the coating, your local climate, and a proper installation.
Is it a difficult DIY project?
If you're comfortable with DIY projects, you can definitely tackle it. The trickiest parts are setting the posts perfectly straight and stretching the mesh tight to avoid sagging, which requires special tools and patience.
