Choosing Plastic Fencing: A Guide to Avoiding a Bad Buy

A plastic fence seems like a simple purchase, until you're faced with a product that turns brittle and breaks after one winter, or a net that can't withstand your energetic pets. Many products promise durability, but in practice, they quickly fall short. This leads not only to frustration but also to unnecessary costs. Before you make a choice, it's crucial to know what to look for to avoid wasting money on a fence that doesn't deliver on its promise.

We've listed the most common pitfalls and the most important specifications for you, so you can make an informed decision.

The Pitfalls: Why Cheap Often Ends Up Being Expensive

Not all plastic fencing is created equal. Marketing terms can be misleading. Pay attention to the following points to avoid disappointment:

1. The "UV-Resistant" Lie: Many manufacturers claim their product is UV-resistant. In reality, this sometimes means nothing more than a thin coating that's gone after one season. The result? The plastic becomes brittle, discolours, and breaks at the slightest touch. A product without proper, built-in UV stabilisation is worthless after a couple of seasons in the sun.
2. Misleading Strength: A fence net might look sturdy on the roll, but its actual tensile strength and tear resistance are crucial. A low-quality net can tear during installation or when an animal pushes against it. This is a particular risk when using it as plastic chicken wire or for other small animals.
3. Incorrect Mesh Size: The size of the mesh determines its application. A mesh that is too large for an aviary mesh will let small birds escape, while a mesh that is too small for a plastic boundary fence can unnecessarily obstruct the view or increase wind load, putting extra pressure on the structure.

Core Parameters: What to Look For

To make the right choice, focus on the specifications that truly matter. These are the technical details that determine the lifespan and functionality of your plastic fencing.

H2: Material Choice: Polypropylene (PP) vs. HDPE

Most plastic fences are made of Polypropylene (PP) or High-Density Polyethylene (HDPE).

• Polypropylene (PP): This material is often molecularly oriented, which provides high tensile strength and rigidity. According to manufacturer TENAX, this process makes their PP nets comparable in strength to metal mesh, but lighter and rust-proof. This makes it suitable for permanent boundary fences and animal enclosures.
• High-Density Polyethylene (HDPE): This material is generally more flexible and also very durable. It's a popular choice for garden mesh and a balcony net, where flexibility and a smooth, non-cutting finish are important.

H2: UV Stabilisation and Weather Resistance

A quality plastic fence has UV stabilisers mixed throughout the material, not just as a surface layer. This ensures the product retains its colour and strength for years, even when exposed to direct sunlight and changing weather conditions. Products that specifically mention resistance to salt corrosion are a good indicator of durability, especially for use in coastal areas.

H2: Mesh Size and Application

Think carefully about the purpose of your fence and choose the right mesh size:

• Small mesh (5-25 mm): Ideal as aviary mesh to keep birds in, as a balcony net for safety, or to prevent small pests from entering your vegetable garden.
• Medium mesh (25-50 mm): A versatile choice for plastic chicken wire, fencing off flower beds, or as general garden mesh.
• Large mesh (>50 mm): Primarily used as a pond net to catch leaves in the autumn or for decorative partitions where maximum visibility is desired.

Key Advantage

It combines the robustness you expect from a permanent fence with the lightweight and rust-proof properties of plastic, making it a practical long-term choice.

Frequently Asked Questions

How long does a plastic fence last?

The lifespan depends heavily on the quality. A cheap, non-stabilised fence can become brittle after just 1 to 2 years. However, a high-quality product made of PP or HDPE with good UV stabilisation can last 5 to 10 years or even longer, depending on its exposure to the elements. Some manufacturers, like TENAX for their Millennium line, even offer a 10-year warranty on their product.

Is plastic mesh strong enough for dogs?

This depends on the dog and the type of mesh. For small, calm dogs, a heavy-duty polypropylene net, such as the TENAX Millennium, may be sufficient to define an area. However, for larger, more energetic, or determined dogs, a plastic fence is usually not the safest choice. In those cases, a traditional metal or wood fence is a better option.

How do you install a plastic fence?

Installation is generally straightforward. You will need posts (wood, metal, or plastic) placed in the ground every 2 to 3 metres. Then, unroll the mesh, pull it taut, and attach it to the posts with zip ties, staples, or binding wire. The major advantage is that the rolls are much lighter and easier to handle than traditional metal mesh.
