It is decided: you are going to install a rigid panel fence. But one question is on your mind: should you choose 4 mm or 5 mm wire? Do not worry—this choice is simpler than it seems. The fencing experts at Districlos explain everything.
Key takeaways
- 4 mm wire: residential standard, lighter, easy to install, affordable price, ideal for marking out a typical garden, small pets, quiet neighbourhood
- 5 mm wire: ultra-rigid and hard-wearing, heavier, perfect for strong winds, maximum security or risk of vandalism
- Decide based on wind exposure, the level of protection required, the type of animals, and your budget
- Essential in both cases: suitable posts and fixings + careful installation for optimal strength
What do 4 or 5 mm correspond to?
The wire diameter corresponds to the thickness of the vertical and horizontal steel wires that make up the mesh panel. A 4 mm wire panel is therefore made of 4 mm-thick wires, while a 5 mm wire panel uses thicker wires.
This simple 1 mm difference changes everything. A thicker wire means more material, so a panel that is heavier, more rigid and more resistant to impacts and attempts to bend it out of shape. This is the main criterion that distinguishes a standard fence from a reinforced fence.
Rigid mesh fencing with 4 mm wire
The rigid panel with 4 mm wire is the most common solution for residential projects. It is the ideal choice for marking out a garden, securing the perimeter of a house in a quiet neighbourhood, or preventing a small pet from escaping. It offers excellent rigidity for most everyday uses.
Its main advantage is its more affordable price. It is also lighter, which makes it easier to handle and install—an important benefit if you are doing the installation yourself.
It is a professional-quality solution that perfectly meets the needs of homeowners looking for an attractive, durable fence without extreme security constraints.
The rigid panel with 5 mm wire
If your priority is security and robustness, 5 mm wire is the option to choose. Its superior rigidity makes it much harder to bend or cut. It is particularly recommended for professional sites, warehouses, and areas exposed to the public or to vandalism.
For homeowners, 5 mm wire is a sensible choice if your property is in a very windy area, if you have a large dog that could jump against the fence, or if you simply want a maximum level of protection and deterrence.
What criteria should you consider to make your choice?
To help you decide, ask yourself the right questions. Your final decision should be based on a combination of these different factors.
- Your property’s surroundings: Is it isolated or in a housing estate? Is it exposed to strong winds or frequent foot traffic?
- The desired level of security: Is it simply a visual boundary, or a real protective barrier against intrusions?
- The presence of animals: A small dog will not put the same pressure on the fence as a large, powerful, energetic dog.
- Your budget: Define the budget you want to allocate to your project, keeping in mind that 5 mm represents an additional cost compared with 4 mm.
The importance of installation and accessories
Whatever wire diameter you choose, the strength of your fence will also depend on the quality of the installation. A 5 mm panel, however robust it may be, will not be effective if it is fixed to unsuitable posts or posts that are poorly set.
Make sure you choose posts and fixings that are compatible with the weight and rigidity of your panels. For 5 mm wire panels, it is often advisable to choose stronger posts and slightly reduce the spacing between them to ensure optimal strength for the entire structure.
