Security fencing is one of the most effective ways to protect your property — whether that’s your family home, business premises, or an industrial site. A good security fence doesn’t just stop intruders in their tracks; it also acts as a deterrent, defines your boundary, and offers everyday peace of mind.
From garden fence security ideas to metal mesh fencing for commercial sites, this guide covers the main types of security fencing, how to keep your fence secure, and what to consider when choosing the best solution for your property.
What is security fencing?
Security fencing is any boundary system designed primarily to prevent unauthorised access. It might be decorative, practical, or both, but its main purpose is protection.
Commercial and industrial sites, in particular, rely on wire mesh security fencing as it is difficult to climb or break through without specialist tools. Generally, we recommend purchasing rolls of 50mm x 50mm welded mesh in either 10 or 12 gauge for use as security fencing. If you’re not sure which gauge you need, be sure to read our guide to wire gauges.
We also recommend heavy-duty chain link fencing. For ease of installation, we have complete chain link kits as well as guides for installing chain link fencing, including which materials are required.
The benefits of security mesh fencing
Among all security fencing types, security mesh fencing stands out as a versatile and effective choice. It’s made from a thicker wire than standard wire mesh, typically at least 2.5mm thick. Wire mesh fencing offers an excellent balance between strength and visibility. Key benefits include:
- Anti-climb design: The small apertures make it very difficult to grip or scale.
- Durability: Galvanised steel resists rust, impact, and tampering.
- Visibility: Mesh fencing doesn’t block light or CCTV sightlines.
- Customisable: Available in different gauges and finishes to suit various settings.
- Low maintenance: Once installed, wire mesh lasts for years with minimal upkeep.
General security fencing tips
Before we look at specific applications, it’s worth understanding the core principles of fence security that apply everywhere.
- Height matters: Taller fences are harder to climb, but check local regulations - residential fences over 2 metres often need planning permission, and this can be reduced to 1 metre if adjacent to a highway.
- Use the correct post spacing: To ensure that your security fence has sufficient support, you should space your posts at approximately 1.8m to 2m intervals for welded wire mesh, and up to 3.15m intervals for chain-link fencing.
- Choose the right fencing: The hole size and thickness of the wire are key, choose a wire mesh with a hole size no bigger than 50mm x 50mm and at least a 2.5mm thick wire.
- Deter climbing: Use anti-climb designs to discourage scaling, such as angled brackets at the top of the fence
- Combine methods: Lighting, cameras, and planting can enhance physical security for minimal extra cost.
Domestic security fencing
If you live in an area prone to break-ins, have valuable items or machinery in your garden, or have had issues with security in the past, you may be considering security fencing for domestic purposes. When it comes to garden fence security ideas, your goal is to make your garden difficult to access and unattractive to opportunistic burglars — all while ensuring your solution is neighbour-friendly.
Welded mesh fencing is ideal for homeowners who want a tough yet discreet barrier. This security mesh fencing offers durability and visibility, meaning there are fewer weak spots for thieves to exploit. It can be used anywhere, but it is especially useful for rural properties or gardens backing onto open land. You can also grow a hedge or thorny plants along the wire mesh boundary to act as a further deterrent and to provide privacy.
For a less industrial look, you may wish to consider installing green PVC coated chain-link fencing as a cost-effective, long-lasting option that’s ideal for rear boundaries or larger plots.
Pressure-treated timber panels are also a popular choice for privacy. However, they can be vulnerable if not properly secured. Reinforce them with wire mesh fencing behind the panels for added strength.

Garden fence security ideas
Not every solution needs to look like a fortress. These garden fence security ideas enhance safety while ensuring you can still enjoy your garden:
- Add height with trellis: Extend your fence up to the legal limit with a decorative trellis.
- Use lighting: Motion-sensor or solar lighting discourages intruders and improves visibility.
- Install security cameras: Both wired CCTV and wifi camera systems provide a great deterrent to unwanted visitors.
- Grow defensive plants along your wire mesh security fence: Thorny species like pyracantha, berberis, and holly can protect boundaries naturally.
- Install gravel paths or borders: The crunch underfoot provides an audible deterrent.
- Use anti-climb paint: Apply it to the top of walls or fences — it stays greasy and hard to grip. Just make sure that you apply the paint at a reasonable height to ensure that passers-by don’t damage their clothing, and that you install appropriate warning signs.
Small upgrades like these can make your home a far less appealing target.
Commercial and industrial security fencing
For businesses, warehouses, and public sector properties, commercial security fencing serves as a crucial first line of defence. Unlike residential setups, these fences prioritise strength and visibility over appearance. Types of security fencing for commercial properties include:
- Welded mesh fencing: The go-to option for modern security installations. It’s difficult to cut or climb, provides a clear line of vision for CCTV systems, and is available in various security grades. It’s best for schools, data centres, warehouses, and transport hubs. Add barbed wire, rotating spikes, or alarm sensors for high-risk sites, although ensure that appropriate warning signs are installed.
- Chain link fencing (heavy-duty): Chain link fencing is cost-effective for large perimeters and adaptable to various security levels. Add barbed wire and tension wire for improved resilience.
How does metal security fencing enhance property security?
Metal security fencing delivers exceptional performance in commercial and industrial environments. Galvanized steel fencing resists cutting, prying, and impact while preventing rust, even in harsh weather. Mesh size, height, and finish can be tailored to your risk level and other requirements, and its high visibility means it works seamlessly with CCTV, motion sensors, or access-controlled gates.
In essence, metal security fencing doesn’t just protect assets — it also reduces long-term maintenance and may reduce insurance costs. Add features such as lighting, alarms, or electronic gates to further enhance protection.
Long-term fence security and maintenance
Although wire mesh fencing is a low maintenance product, it is still a good idea to routinely inspect your perimeter particularly after storms or strong winds, to check for loose fixings or damage. Repair promptly, replacing damaged sections quickly before the integrity of your security fence is compromised.
A well-maintained fence lasts longer, looks smarter, and continues to deliver reliable protection. Keep tension wires tight to prevent sagging in mesh or chain link systems, and repair or replace any damage or gaps in your boundary fence.
Finally, remember to check all secure gates and locks. These are often the easiest access points, so keep them strong and well-maintained.
