Installing rigid panel fencing is a long-term project to secure and delimit your property. However, with weathering, pollution, and the passage of time, the choice of materials is crucial. When making your decision, a question often arises: is it better to choose raw galvanized mesh or a plastic-coated version?
At Districlos, we compare these two finishes to help you find the one that will best withstand the elements at your home.
Galvanized Rigid Fencing: The Raw Strength of Steel
Galvanization involves dipping steel into a bath of molten zinc. This treatment creates an ultra-resistant protective layer that bonds with the metal. Water and air can no longer come into contact with the steel, which eliminates the risk of rust.
The main advantage of galvanized fencing is its robustness against impacts. Mower strikes, animal scratches, or friction do not chip it. It’s the logical choice for agricultural land, industrial sites, or simply if you’re looking for functional protection without aesthetic frills.
Plastic-Coated Rigid Fencing: A Double Protective Barrier
It is sometimes imagined that plastic-coated fencing is simply a plastic sheath placed over raw metal. In reality, a quality panel first undergoes galvanization, then receives an adhesion primer before being coated with polyester or PVC.
This double protection very effectively blocks moisture. Beyond this technical aspect, plastic coating provides a more refined finish. The green, anthracite grey, or black shades allow the fence to be neatly integrated into a residential garden.
Against Corrosion: Which Treatment Lasts Longest?
Under normal conditions, both types of panels easily last more than 15 or 20 years. The plastic-coated model offers better overall protection against oxidation, on one condition: that the surface is not deeply cut.
If a deep scratch penetrates the plastic layer down to the steel, moisture will seep in, and rust can form under the coating. Conversely, on a hot-dip galvanized panel, a scratch is not a problem. The zinc around the wound sacrifices itself to continue protecting the exposed steel.
The Impact of Sun and Climate
Raw galvanized steel is not affected by ultraviolet rays. Over time, it loses some of its brilliant shine to take on a matte patina, but its structure remains unchanged.
For plastic-coated fencing, the quality of the coating is paramount. Professional panels incorporate anti-UV treatments so that the polyester does not ‘cook’ and fade under the sun. Avoid entry-level products: under the effect of UV, their plastic eventually cracks, allowing water to infiltrate and rust the wire from the inside.
How to Choose Based on Your Region?
The local climate is an excellent indicator for making your choice:
- By the sea: Salty air accelerates zinc corrosion. Plastic-coated fencing is essential here, as the polyester acts as a barrier against salt.
- In the city or near an industrial area: Pollution and acid rain wear down zinc faster. The double protection of plastic is therefore recommended.
- In the countryside or at the edge of a forest: Raw galvanized fencing is perfectly suitable. It tolerates contact with wild vegetation or the passage of animals very well.
The Importance of Wire Diameter and Structure
The thickness of the metal affects the lifespan as much as the surface treatment. A wire that is too thin will deform under wind or impacts, which eventually cracks the protective layers.
For a lasting installation, check these few points:
- Opt for a wire diameter of 4 to 5 mm to ensure true rigidity.
- Prefer panels with well-defined reinforcing folds.
- Examine the welds: they must be clean and perfectly treated, as this is often where rust begins.
