PL2 is fitted with a pair of automated bottom restraint devices that will work with the motor operator to ensure that the restraints will always engage whenever the shutter is in the closed position. PL2 has been tested and shown to be capable of achieving limited damage and be fully retained in response to a blast load with a peak pressure of 40 kPA and peak impulse of 500 kPa-ms.

PL1 (without bottom restraints) has been tested and shown to be capable of achieving limited damage in response to a blast load with peak pressure 75 kPA and peak impulse 1050 kPa-ms。


Blast Resistant & Mitigating Shutter

Engineered for Maximum Safety in High-Risk Facilities

Conventional roller shutters can become dangerous projectiles during explosions due to flammable material releases. This poses a significant safety risk in oil and gas facilities. In collaboration with ABS Consulting (USA), we have developed a revolutionary blast-resistant roller shutter system to address this critical issue.


  • Enhanced Safety: Gliderol's blast-resistant shutters significantly minimize explosion risks in oil and gas facilities by eliminating debris hazards.

  • Improved Facility Resilience: These shutters ensure operational continuity by sustaining minimal damage during a blast event.

  • Advanced Design Flexibility: FEA-based design allows for customization to suit specific facility requirements and blast threats.

Technica Two-Phase Development 

  1. ​Finite Element Analysis (FEA): This advanced computer modeling technique precisely simulates blast impact on the shutter system, enabling optimal design optimization.

  2. Full-Scale Shock-Tube Testing: Real-world validation of the FEA model is achieved by subjecting two full-scale working models (W 3700mm x H 4950mm) to controlled explosions within a shock tube.

Innovative Design Approach

  • Controlled Deformation: The shutter curtain undergoes controlled plastic deformation under blast pressure, effectively absorbing the impact energy.

  • Progressive Arrest System: Moving components are strategically designed to progressively slow down and ultimately come to a complete stop, preventing debris generation.

  • Interconnected Components: Horizontal steel connector rods and vertical wire ropes, securely connected on both sides, ensure the curtain remains intact during a blast. PL1 configuration features unrestrained bottom wire ropes, while PL2 utilizes tethered ones for additional security.

Validation and Performance

  • Shock Tube Testing: Both PL1 and PL2 configurations underwent rigorous shock tube testing, demonstrating excellent agreement between the FEA model and real-world results.

  • Minimal Damage & Zero Debris: Tests confirmed minimal permanent damage to the shutters, with zero debris generation, highlighting their exceptional safety profile.

  • FEA Model Reliability: This successful validation establishes the FEA model's reliability for predicting performance under varying dimensions and blast loads, ensuring future design flexibility.
