Plastic Fencing Buyer’s Guide: How to Choose Wisely

Looking to fence in your garden, secure a balcony, or protect your vegetable patch? Plastic fencing seems like the perfect solution: simple, cost-effective, and efficient. In theory. In practice, many buyers are disappointed by a product that disintegrates after the first winter, can't withstand the neighbour's cat, or turns out to be a nightmare to install. To prevent a good idea from becoming a bad investment, here's how to avoid the most common pitfalls.

Here are 3 frequent mistakes that can turn a good idea into a bad investment:

1. The Illusion of UV Protection: This is a classic on product sheets. Many entry-level fences boast a "UV-resistant" label, but this is often just a surface treatment. The result? After one summer, the plastic becomes as brittle as glass, the colour fades to a washed-out pastel, and the mesh tears at the slightest touch.
2. Mesh Unsuitable for the Application: Choosing a mesh that's too wide for a balcony safety net is an open invitation for small objects to fall... or for a kitten to escape. Conversely, a mesh that's too tight for staking your tomato plants could stifle their growth.
3. Finishing That Betrays Quality: Raw, sharp, or unreinforced edges? That's a red flag signalling a low-quality product. Not only does installation become a risky ordeal for your hands, but these weak points are also the first to give way once the fencing is put under tension.

The Essential Criteria for an Informed Choice

To be sure of your decision and choose a plastic fence that will live up to its promises, forget the marketing slogans for a moment and focus on these few decisive technical points.

1. Material and UV Stabilisation

The type of plastic is the first clue to its longevity. The two main types are:

• High-Density Polyethylene (HDPE): Known for its flexibility and excellent resistance to impacts and chemicals. It's the go-to choice for versatile fencing.
• Polypropylene (PP): Often more rigid and with excellent tensile strength, it's perfect for more structured fences or applications requiring high durability.

But the real secret, the non-negotiable criterion, is mass-stabilised UV protection. In practical terms, this means the protective agents are mixed into the plastic at the source, not just sprayed on the surface. A UV-resistant fence designed this way will retain its flexibility and colour for years.

2. Mesh Size and Shape

The shape of the mesh (square, rectangular, hexagonal) and especially its size will directly dictate how you can use it.

• Small, tight mesh (10x10 mm to 20x20 mm): Ideal as a fall-protection net on a balcony, to prevent leaves from clogging gutters, or for building enclosures for very small animals (rodents, chicks).
• Medium mesh (30x30 mm to 50x50 mm): This is the all-purpose mesh. It's perfect for a plastic garden fence, securing a railing against a cat or small dog, or serving as a support for your climbing plants.
• Large mesh (> 50 mm): This is generally reserved for agricultural fencing, marking out large plots of land, or creating poultry enclosures (like a chicken run net), where good air circulation is essential.

3. Structure and Edges

A good roll of plastic fencing should be a pleasure (or at least, not a chore) to install. Carefully inspect the edges of the net: smooth, reinforced edges, also known as selvedges, are an excellent indicator of quality. They simplify attachment (with zip ties or staples), distribute tension more evenly, and prevent tears at the first gust of wind. It's the guarantee of a clean, long-lasting installation.

Our Plastic Fencing Recommendations

How it avoids the pitfalls

Its unique manufacturing process (molecular bi-orientation) gives it unparalleled strength. No more falling into the trap of fencing that seems sturdy but gives way under intensive use.

Key advantage

Despite its robustness, it remains much lighter and more manageable than a metal fence of equivalent dimensions. A decisive advantage when you need to cover long distances.

Frequently Asked Questions

How do I install plastic mesh on a balcony?

It's very simple. Unroll the mesh along the railing. Secure it firmly with plastic zip ties or staples, placing one every 20 to 30 cm. Remember to pull the net taut during installation for a clean result and maximum safety.

What is the lifespan of UV-resistant plastic fencing?

It all depends on the quality of the UV treatment. An entry-level model will barely last one or two seasons. Conversely, a quality fence with "mass-stabilised" treatment (in stabilised HDPE or PP) can easily last between 5 and 10 years, and even longer, depending on its sun exposure.

Can plastic fencing be used as a privacy screen?

A model with a very fine mesh can indeed create a light privacy screen effect and filter views. However, for complete obscurity and true privacy, it's better to opt for a dedicated solution like a reed screen or an occultation fabric. The primary role of plastic fencing remains demarcation and protection, not to block the view.
