Fire Rated Blast Doors

Defence Doors Ltd continue to design, develop and test new products, the latest addition to the bespoke blast door range is a composite blast door design and tested for the petrochemical industry. The steel door sets are primarily designed as blast resistant doors combined with fire certification to 4 hours and tested to BS EN 1634-1:2000. The doors are equipted with external lever handle for key entry and internal panic bar assemblies for use as emargency exits.

The images below show the testing of the fire rated blast door from the installation to the opening of the kiln and removal of the door set. The test was terminated at 4hrs 20mins, this was not due to failure of the door set but due to the fact there has never been a requirement for certification of steel door past 4hrs. The operating temperature of the kiln at the point of termination was in excess of 1150 degrees
