Typhoon tested security shutter

“With our knowledge of the intense pressures generated by powerful storms we decided to develop the Typhoon shutter even further, urged on by our contacts in South East Asia,” says Doug Hart, chairman, Hart Door Systems.

“The result has been remarkable. For the purpose of testing we trawled Europe for a suitable third-party testing facility and found just one that was capable and that was in south west Germany. Given the time, distance and costs that would be incurred we designed and built our own test rig.

“With a steel cage adequate for the pressures, retaining a flexible pressure vessel with a 8m wide and 2.5m high shutter for testing, we were able to sustain pressures at 5050 pascals, equivalent to the pressures generated by a Typhoon blowing at around 165mph.”
