Normal roller shutters including heavy duty ones or cyclone shutters (max pressure 15 kPa) are not designed to withstand blast pressure. When an explosion occur, the shutter horizontal slats or panels are likely to detach from the shutter guides and fly in depending on the blast pressure and the severity of the threat. A blast resistant roller shutter is desirable in view of the lesser material used and also ease of operation compared to conventional solutions like blast doors. We have designed and validated our analysis through a full scale blast test in accordance to ASTM F2927 standards.

Blast Resistant Roller Shutter (Installed on-site)

Live Blast Test


Ideal for openings (e.g at commercial, industrial and military buildings) where blast protection is necessary


  • Field tested with blast loads up to 250kPA.


  • Can be engineered and customised to protection needs.


  • Can be installed at new buildings or retrofitted to existing buildings.


  • Minimum disruptions to operational needs.


  • Easy to operate.


  • Low maintenance costs.


  • Meets fire statutory requirement (2hrs fire-rated).

Composites such as Fiber Reinforced Polymer (FRP) is now widely used in strengthening structural elements against conventional loading, and also extreme loads such as blast loading from explosions. FRPs can be used in new built structures or be retrofitted onto existing ones. Conventional FRP has its limitations due to its labor intensive application such as resin impregnation on site, requirement of mechanical fasteners etc.


A semi-cured FRP has been developed analogous to the "double-sided" tape concept where the pre-fabricated FRP rolls can be readily and easily applied on site. This FRP application will be less dependent on the skill of workers, has more consistent finishing and requires no resin impregnation on site. Design models are analysed and it has also been blast tested for its structural protection capabilities.


  • Up to 30% in cost savings in manpower and time.


  • Easy application halves installation time as it does not require on-site equipment.


  • Factory-controlled quality, unlike conventional method where quality is highly skill-dependent.


  • Reinforces bare concrete structures to achieve up to twice the loading capacity.
