The ULAMEX Fence Mesh is a heavy-duty welded wire mesh panel manufactured from galvanised steel, designed specifically for solar farm perimeter security, industrial site fencing, and critical infrastructure protection. With a tight 6.5×6.5 mm mesh opening, these panels deliver superior anti-climb and anti-cut performance compared to standard 50×200 mm or 76×76 mm mesh products, making them the preferred choice for high-security photovoltaic installations where theft of copper cabling, inverters, and solar panels represents a significant financial risk.

Installation
Mount the fence mesh panels to round tubular fence posts (42.4 mm or 48.3 mm diameter) using appropriate fencing mesh accessories — mesh clamps, saddle clips, and anti-tamper fixings. Space posts at intervals of 2000–2500 mm depending on wind exposure and required rigidity. For the 2000 mm height variant, set posts a minimum of 600 mm into the ground (concrete foundation recommended) to achieve a total above-ground fence height that meets insurance and grid operator requirements for solar farm perimeters.
Where additional security is required, add three rows of barbed wire above the mesh panel using angled barbed wire arms mounted to the fence post tops. This combination — 2000 mm mesh plus 450 mm barbed wire extension — delivers a total barrier height of approximately 2450 mm, exceeding the minimum requirements of most European solar farm insurance policies and grid connection agreements.
The tight 6.5 mm mesh aperture prevents hand- and foothold insertion, making the fence panel inherently anti-climb without requiring additional security toppings in low-to-medium risk environments. Cut the mesh to size on-site using standard bolt cutters or angle grinders with a cutting disc.
Applications
- Solar farm perimeter fencing — the primary application, protecting PV arrays, inverters, transformers, and cabling from theft and vandalism. Grid operators and insurers frequently mandate perimeter fencing as a condition of connection and coverage.
- Substation and transformer enclosures — high-voltage areas within solar farms requiring additional physical barriers
- Industrial site security — warehouses, logistics yards, manufacturing facilities, water treatment plants
- Construction site temporary fencing — robust mesh panels that can be relocated between project phases
- Agricultural enclosures — livestock barriers, crop protection, estate boundaries
Material & Corrosion Protection
Each mesh panel is electrically welded at every wire intersection, creating a rigid, self-supporting structure that maintains its shape under impact and wind loading. The hot-dip galvanised finish to EN ISO 1461 provides a zinc coating thickness of 40–70 µm on the wire surface, delivering a maintenance-free outdoor service life of 15–25 years depending on atmospheric corrosivity (EN ISO 9223 category C1–C3).
For installations in coastal, industrial-atmospheric, or chemically aggressive environments (category C4–C5), additional protection can be applied via powder coating or PVC sheathing over the galvanised base. The all-steel, all-galvanised construction is compatible with galvanised fence posts and galvanised accessories, eliminating bimetallic corrosion risks across the entire fence line.
Compatibility
- Fence posts — round tubular galvanised steel, 42.4 mm × 1.5 mm and 48.3 mm × 2.0 mm
- Fencing mesh accessories — clamps, caps, clips, and strainer holders for 42.4/48.3 mm posts
- Barbed wire — 2.0 mm galvanised steel, top-line security extension
- Earthing rod connectors — grounding the fence line into the solar farm earthing network
- PV mounting profiles, clamps, and fasteners — the complete solar farm material package

Frequently Asked Questions
- What is the advantage of 6.5 mm mesh over standard 50×200 mm panels?
- The 6.5 mm aperture is too small for fingers or tools to penetrate, making the panel inherently anti-climb and anti-cut. Standard 50×200 mm mesh can be climbed using footholds and cut with basic hand tools.
- What height should I choose for a solar farm?
- Most European solar farm insurance policies and grid connection agreements require a minimum fence height of 1800–2000 mm. We recommend the 2000 mm panel, optionally topped with barbed wire for additional deterrence.
- Can the mesh be powder-coated?
- Yes, the galvanised base accepts powder coating in RAL colours. Contact us for custom-colour orders on project quantities.
- How many panels per linear metre?
- Panel width depends on post spacing, typically 2000–2500 mm. A 100-metre fence line with 2500 mm post spacing requires 40 panels plus corner and gate posts.
