A security fence is a physical perimeter barrier designed to prevent unauthorized access and entry to a property or area. The main purpose of security fences is to provide an extra layer of protection and deterrence against intruders, trespassers, and other security threats. Security fences are an important component of any comprehensive security system. They serve as the first line of defense and make it more difficult for potential intruders to gain access to a secured area. Well-designed and properly installed security fences act as a psychological deterrence as well as a physical barrier. Engaging reputable fencing contractors Aldershot ensures that your security fence is installed with precision and expertise, maximizing its effectiveness in safeguarding your property.
Types of Security Fences in the UK
The UK market offers many types of security fences suitable for a range of applications and security needs:
Perimeter Security Fences
High-Security Perimeter Fences
Characteristics:
- Heavy-duty metal construction
- Defensive spike/barbed wire topping
- Sturdy posts encased in concrete
- Hard to cut, climb or breach
Applications: High-risk facilities, critical infrastructure sites, government buildings
Medium-Security Perimeter Fences
Characteristics:
- Robust welded mesh fencing
- Interwoven barbed wire toppings
- Secure locking gates
- Durable materials like galvanized steel
Applications: Commercial complexes, industrial units, construction sites
Temporary Security Fences
Characteristics:
- Portable modular metal panels
- Easy quick installation
- Often rented for short-term uses
Use Cases: Construction/renovation sites, temporary events, vacant property protection
Specialized Security Fences
Electric Fences
Features:
- Live wire that delivers non-lethal electric shock
- Warning signs for deterrent effect
- Remote monitoring capabilities
Legal Considerations: Require signage as warnings per government regulations, certification needed for installers
Anti-Climb Fences
Design Features:
- Defensive spike tips, barbed/razor wire
- Curved inwards or outwards top edging
- Smooth surfaces lacking hand/footholds
Deterrent Properties: Inflict injury if climbed, delay and trap climbers, visible hazard signs
Key Features of Security Fences in the UK
Material Selection
An important consideration for security fences is choosing suitable materials optimized for safety, strength, and durability:
Metal Fences
Steel – galvanized or stainless steel offers high tensile strength. Robust, vandal-proof, cut-resistant. Requires anti-rust treatments.
Aluminum – corrosion-resistant, long-lasting. Lower hardness than steel but suitable for many applications.
Iron – durable option when treated/coated but prone to rust. Typically the most cost-effective metal fencing.
Mesh Fences
Characteristics: Interwoven wire mesh fencing provides see-through visibility while having no climb properties. Available as chain link or welded mesh in various gauge thicknesses.
Applications: Commercial complexes, schools, car parks, warehouses. Can be topped with barbed wire for higher security.
Height and Design
Height is another vital aspect that determines the security level and suitability of fences:
Standard Height Considerations
- Commercial fences usually vary from 2-2.5 m height
- Government regulations limit residential area fences to 1m
- Taller 3-5m electric/metal perimeter fences require council permits
Customizable Designs
Security fences offer customized sizing/height and layouts to meet site-specific protection needs. Professional security firms conduct vulnerability assessments and threat modelling to determine optimal fencing height and layouts for maximized protection.
Security Add-ons
Additional fixtures can enhance protection offered by the fence system:
CCTV Integration
Importance – Live monitoring deters and identifies intruders. CCTV meshes well with access control.
Implementation – Strategic placement of security cameras provides optimal visibility coverage alongside the fence, with feeds monitored from a central room.
Access Control Systems
Biometric Systems – verify identity via fingerprints or facial recognition to allow access.
High security suited for sensitive sites.
Keycard Systems – convenient tapped access but less secure than biometrics. Better for commercial properties.
Installation and Maintenance
Professional Installation
Importance – Proper installation critical to achieve optimal security from fence systems. Reduces risk of damage and breaches.
Hiring Considerations – Only experienced security firms certified in fence installations should be hired. Factors like warranty periods and quality of workmanship should be evaluated.
Maintenance Practices
Regular Inspections – Yearly scheduled check-ups assess damage from weather/vandals. Important for early breach prevention.
Repairs and Upgrades – Timely fixes/enhancements done as needed maintain protective functionality and bolster vulnerabilities.
Frequently Asked Questions
What are the legal requirements for security fences in the UK?
Certain fence types require permits from local authorities, especially for electric fences and any above 1m height in residential areas. Warning signs needed as well for electric/barbed wire fences citing safety hazards.
How do I choose the right security fence for my property?
Conduct vulnerability/threat assessments weighing factors like asset value and security risks. Also consider visibility needs, aesthetics and legal fence height limits in locations. Seek professional consultation to select optimal fence types/features that offer suitable levels of protection.
Are there any regulations for installing electric fences in residential areas?
Electric fences above mains voltage require permits and certified installation/maintenance. Warning signs needed citing voltage. In residential areas they face more legal restrictions and usually require special authorization only given in certain cases.
What is the average lifespan of a security fence?
When regularly maintained and repaired, a high quality welded steel mesh or reinforced metal fence has an average lifespan ranging from 15-25 years. Some industrial grade steel fences may last over 30 years.
Can security fences be installed on uneven terrain?
Yes, modern security fencing is designed for adaptation to most terrain profiles including uneven or sloped landscapes. Professional installation is vital to anchor fence posts and achieve stability on inconsistent ground.
Are there eco-friendly options for security fences?
Some vendors offer security fences made from sustainable HDPE composite lumber or recycled plastic instead of steel/lumber. Eco-friendly coatings on metal fencing are also an option to prevent rust/toxins leaching when weathering.
How effective are anti-climb features in preventing unauthorized access?
Research shows properly designed/installed anti-climb fixtures such as curved barbed wire topping can reduce scaling by over 75-80%. Combined with greater height/surveillance, protection against unauthorized climbing attempts is significantly enhanced.
What are the cost considerations for installing a security fence?
Key variables affecting cost include – fence height/length based on perimeter, materials selected and fixtures/features added. For a basic guide, steel mesh fencing starts around £55-£100 per meter including professional installation. Ongoing maintenance costs also a factor.
