Blast-resistant fire doors
We have developed a composite blast door designed and tested for use in petrochemical applications. These steel door sets are merge the principles of blast design with the requirements of 4- hour fire certification and are tested to BS EN 1634-1:2008.
The doors leads are formed from 5mm thick mild steel plate sandwiching a mild steel framework. The frame is face-fixed with anchor bolts to the masonry surround on the exposed side and to the inside face of the masonry surround on the unexposed side.
They come equipped with an external lever handle for key entry and internal panic bar assemblies for use as emergency exits.
