How A-1 Fence is Setting the National Benchmark for Forced-Entry Delay Protection
In today’s evolving threat landscape, perimeter security is no longer about simply preventing access; it is about buying time. Time for detection, time for response, and time to neutralise threats before they escalate. This is where delay-rated fencing systems play a critical role, forming the first and most decisive line of defence for critical infrastructure.
As India continues to invest in data centres, transport corridors, defence installations, energy assets, and strategic facilities, the demand for certified, performance-tested perimeter solutions has never been higher. At the forefront of this evolution stands A-1 Fence, India’s leading provider of SR1, SR2 and advanced delay-rated fencing systems, engineered and delivered to global security standards.
What are delay rated fences and why they matter
Unlike conventional perimeter fences, delay-rated fences are tested to withstand forced entry attempts using specific tools for a defined minimum time. The objective is not just deterrence, but measurable resistance, slowing intruders long enough for alarms to trigger and response teams to act.
International standards such as LPS 1175 (UK) and ASTM frameworks define how fences are tested, the tools used, and the delay times achieved. For high-risk sites, these certifications are no longer optional; they are now essential.
A-1 SR1 Rated Fence: Certified protection for medium-risk perimeter
The A-1 SR1 Rated Fence, certified to LPS 1175 SR1, offers a minimum 1-minute forced entry delay against basic hand tools. This makes it ideal for sites where opportunistic intrusion is the primary concern.
Key advantages:
- Certified SR1 Delay Performance under LPS 1175.
- Anti-climb welded mesh with tight apertures to eliminate hand and footholds.
- High visibility design, maintaining clear CCTV and patrol sightlines.
- Hot-dip galvanised and powder-coated finish for long-term corrosion resistance.
- Cost-effective security upgrade over conventional fencing.
Typical applications:
- Commercial and industrial estates.
- Warehouses and logistics parks.
- Educational campuses.
- Utility yards and service depots.
For organisations seeking certified protection without over-engineering, A-1 SR1 provides the ideal balance of deterrence, delay, and value.
A-1 SR2 Rated Fence: High-security protection where every second counts
When threats are more deliberate and determined, A-1 SR2 Rated Fence delivers the next level of assurance. Tested and certified to LPS 1175 SR2 (Issue 7)/ B3 (Issue 8), this system provides a proven 3-minute delay against enhanced hand tools.
Key advantages:
- Certified 3-minute forced entry delay.
- Reinforced anti-climb mesh design with increased wire strength.
- High visibility index (42%) for superior surveillance integration.
- Corrosion-resistant galvanised and powder-coated finish.
- Fully compatible with PIDS, electric fence, and radar systems.
Typical applications:
- Data centres and digital infrastructure
- Industrial plants and manufacturing hubs
- Transport infrastructure and logistics terminals
- Government and utility facilities
SR2 fencing is designed for environments where response time is mission-critical – and where perimeter failure is not an option.
A-1 AKAT® NG 30: Extended Delay Protection for High-Threat Environments
For assets where intrusion attempts are likely to be deliberate, equipped, and persistent, A-1 Fence offers its most advanced delay-rated solution – ASTM-certified A-1 AKAT® NG 30. Engineered specifically to counter aggressive cutting and climbing attacks, AKAT NG 30 is designed to deliver extended forced-entry delay beyond conventional SR ratings, making it suitable for the highest-risk perimeters.
Through its high-strength welded construction and anti-cut geometry, AKAT NG 30 achieves delay times of up to 30 minutes against medium cutting tools and provides significant resistance of more than 6 minutes even against aggressive power tools, giving response teams a decisive operational advantage. Unlike standard anti-climb fences, AKAT focuses on measured delay performance, not just deterrence.
Key advantages:
- Up to 30 minutes delay against medium cutting tools.
- High resistance to aggressive mechanical cutting attempts.
- Advanced anti-cut and anti-climb welded mesh design.
- Engineered for integration with electric fencing, PIDS, and surveillance systems.
- Designed for critical national infrastructure and high-threat zones.
A-1 AKAT® NG 30 is purpose-built for defence installations, border security, data centres, energy facilities, and other strategic assets, where every additional minute of delay directly translates into enhanced threat neutralisation and site security.
Engineering That Goes Beyond the Fence
What sets A-1 Fence apart is not just certification, but system-level thinking. Every delay-rated fence is engineered as part of a layered security ecosystem, seamlessly integrating with:
- Fence-mounted and buried PIDS systems.
- Electric fencing and fibre-optic detection.
- Surveillance, access control, and command centres.
- Site-specific response strategies.
Equally important is durability. A-1’s hot-dip galvanising and powder coating processes ensure long-term corrosion resistance, a critical factor for India’s diverse climates and harsh environments.
Why A-1 Fence Leads the Delay-Rated Segment in India
- Proven expertise in certified delay-rated fencing.
- In-house design, engineering, and manufacturing.
- Global standards, locally delivered.
- Solutions tailored for Indian threat scenarios and terrain.
- End-to-end capability, from design to execution.
With over 25 years of perimeter security excellence, A-1 Fence has helped redefine how Indian infrastructure thinks about perimeter protection, shifting the conversation from ‘can it be breached?’ to ‘how long can it be held?’
Conclusion: Delay is the New Defence
In modern security design, delay equals control. Whether it is SR1, SR2, or advanced AKAT systems, delay-rated fencing gives security teams the most valuable asset of all: time.
As India’s infrastructure grows more complex and critical, A-1 Fence continues to lead the way, delivering certified, performance-driven perimeter solutions that stand up to real-world threats. A-1 Fence, Engineering Time. Securing the Nation.
