In an era where perimeter security is no longer optional but essential, infrastructure protection requires solutions that combine strength, speed, reliability, and certified impact resistance. B&K Security answers this demand with its Trackless Bi-Folding Crash Rated Speed Gates — a next-generation security system designed to protect critical buildings and perimeter entrances against vehicle-borne attacks.

Engineered for high-risk, high-demand environments, these gates deliver uncompromising protection while maintaining fast operational performance and architectural integration.

Designed for High-Threat Environments

B&K Security’s bi-folding speed gates are specifically developed for facilities where security failure is not an option. Typical applications include:

  • Government and military facilities
  • Petrochemical and energy infrastructure
  • Banking and financial institutions
  • Transportation hubs
  • Public utilities and critical infrastructure sites

Each gate is designed, manufactured, installed, commissioned, and maintained by B&K Security’s team of experienced engineers, ensuring a complete lifecycle security solution — from concept to long-term operation.

Certified Crash Protection

Security is only as strong as its certification. These gates are crash-rated by design and engineered to withstand extreme impact forces:

Crash Rating (Impact Resistance):

Designed to stop a 2,500 kg vehicle traveling at 48 km/h, compliant with:

  • PAS 68:2013
  • IWA 14-1:2013

This level of protection makes the system suitable for anti-terrorism and hostile vehicle mitigation (HVM) applications, providing proven resistance against vehicle-borne threats.

Structural Engineering Excellence Gate Construction

  • Gate leaves manufactured from rectangular hollow sections (RHS)
  • Heavy-duty support posts made of square hollow sections (SHS)
  • Integrated steel anchoring plates for secure fixing at finished floor level

This robust construction ensures long-term durability, structural stability, and impact resistance even in extreme operating conditions.

Flexible Design & Infill Options

The system offers full customization to meet architectural and security requirements:

Available infill options:

  • 25 × 25 mm square profile infill
  • Mesh infill
  • Fully custom infill solutions on request

This allows seamless integration into different environments — from industrial facilities to sensitive urban locations.

Advanced Locking & Arrestor System

Each gate is equipped with a solid mechanical locking system integrated with an arrestor mechanism, ensuring:

  • Secure closure under impact loads
  • Structural stability during collision events
  • Enhanced resistance against forced entry

This combination plays a critical role in maintaining crash performance integrity.

Premium Drive Technology

At the heart of the system is a high-performance 3-phase electric drive unit, engineered for heavy-duty, high-frequency operation:

Drive Unit Features:

  • Integrated gearbox and PLC controller
  • Manual override for emergency operation
  • Adjustable cam-operated limit switches
  • Dedicated protective housing
  • Dual worm-gear transmission system

The dual worm-gear system provides inherent self-locking functionality, ensuring the gate remains securely in position during power failures and extreme weather conditions, including high winds.

Reliability in Extreme Conditions

These gates are built for environments where standard systems fail:

  • Operational temperature range: down to –45°C
  • Designed for continuous, demanding operation cycles
  • Smooth, controlled motion during both opening and closing
  • Stable performance in high-wind and extreme weather environments

This makes them ideal for remote facilities, harsh climates, and mission-critical infrastructure.

Key Dimensions

  • Clear opening width:
    • Up to 4000 mm (single gate)
    • Up to 8000 mm (double gate configuration)
  • Gate height: up to 4000 mm

This scalability allows the system to protect large vehicle access points without compromising speed or safety.

Security Without Compromise

B&K Security’s Trackless Bi-Folding Crash Rated Speed Gates represent the intersection of engineering precision, certified protection, and operational efficiency. Designed not only to resist impact, but to function reliably every day in the most demanding environments, they provide a future-proof perimeter security solution for modern critical infrastructure.

When security must be absolute, performance must be proven, and reliability must be guaranteed — B&K Security delivers.
