BOS fire rated door frames

Fire rated steel frames

Is there a standard fire rated steel frame?

BOS Best Of Steel frames are an essential element in doorset assembly, as it is the complete doorset assembly which is tested for either fire or acoustic performance. Under BS or EN, the door frame alone is not certifiable. The American standard of UL10c does, however, allow just the frame to be certified and labelled as a fire rated element and BOS holds this certification.

BOS Best Of Steel systems are extensively used in fire rated doorset assemblies. However, it is the responsibility of the door producer or doorset provider to ensure the doors are correctly manufactured, the door size and configuration conforms with the certification, the profile and position of the frame within the aperture is acceptable, the hardware used is correctly certified for use with a steel door frame and any specific installation instructions provided are according to the test evidence used.

Do you have fire protection test evidence for your steel frames with a steel door?

BOS Best Of Steel and DOMOFERM can supply complete fire rated elements, according to DIN EN1634, from our own wide range of fire rated glazing and fire rated steel door elements. DOMOFERM Best Of Steel fire-protection steel door elements provide safety when every minute counts in saving lives and assets. The basic principle of all fire-safety design is to keep escape routes free of smoke and fire. We all rely on perfect fire protection products to ensure the effective rescue of people and possessions. As all fireproof doors need to close automatically, it is extremely important that all components of the steel frame element work together perfectly. In general, only tested elements, consisting of a steel frame, a door leaf and all necessary door components, such as automatic door closers and special fireproof fittings, may be used in areas with fire protection requirements. As it is imperative to have an element which functions 100% all of the time, it is not possible to acquire a single standard fire rated steel frame.
