So, what is security fencing? And how do the different systems compare?

What is Security Fencing?

Security fencing refers to physical barriers specifically designed to deter, delay, or prevent unauthorised access. Used across a wide range of sectors, from infrastructure and utilities to education, healthcare, and logistics, security fences vary in terms of mesh type, strength, and certified resistance levels.

Types of Security Fencing: Uses, Pros and Cons

1. 358 Prison Mesh
What is it? 358 mesh (also known as prison mesh or anti-climb mesh) is a high-security welded panel with a small aperture (76.2mm x 12.7mm) that makes it extremely difficult to climb or cut.

Common Uses:

• Prisons and detention centres
• Data centres
• Utilities and substations
• High-risk industrial zones

Pros:

• Excellent anti-climb and anti-cut properties
• Highly durable and weather-resistant
• Can integrate with CCTV and detection systems

Cons:

• More expensive than standard mesh options
• Reduced visibility compared to wider aperture meshes

From school grounds to secure government facilities, security fencing is essential in modern construction. Whether you need anti-climb mesh, aesthetic perimeter systems, or certified SR-rated mesh, the right solution depends on the risk level and performance requirements.

2. Multi Mesh Systems

What is it? Multi mesh fencing combines different mesh patterns and gauges into one panel, balancing strength and visibility. It offers increased protection without the bulk of prison mesh.

Common Uses:

• Commercial premises
• Business parks
• Mixed-use developments

Pros:

• Versatile and customisable
• Balances security and aesthetics
• Ideal for medium-risk sites

Cons:

• Not suitable for high-security or government-grade applications
• Less resistant to advanced intrusion tools than SR-rated mesh

3. Profile V Mesh

What is it? A popular perimeter fencing option with a V-shaped pressed profile, offering strength and visual appeal. Profile V Mesh is widely used in schools, retail, and residential developments.

Common Uses:

• Education facilities
• Retail parks
• Sports grounds and residential estates

Pros:

• Cost-effective
• Good visibility and aesthetics
• Quick to install

Cons:

• Not suitable for high-risk or restricted-access areas
• Easier to scale or breach than specialist mesh types

4. SR1, SR2 & SR3 Security Mesh (LPS 1175 Rated)

What is it? These are government-approved mesh fencing systems tested and rated under the Loss Prevention Standard (LPS) 1175, which defines how long a fence can withstand a physical attack using specific tools.

Common Uses:

• Defence and government sites
• Airports and data centres
• Critical infrastructure

SR1:

• Tested against basic tools like knives and pliers
• Ideal for low to medium threat sites

SR2:

• Resists attacks with more robust tools like bolt cutters and saws
• Suitable for medium-risk commercial applications

SR3:

• Withstands sustained attacks with power tools
• Best choice for high-risk or high-value sites

Pros:

• Certified protection levels (LPS 1175)
• Can be integrated with gates, alarms, and electronic systems
• Peace of mind for specifiers and end clients

Cons:

• Higher cost depending on the SR level
• Requires professional installation for full compliance
