Durability
These Fire Doors were subject to 1 million opening and closing cycles to simulate real life conditions in a busy hospital environment. The same door then went on to comfortably outperform a 30 minute fire resistance test. The entire range achieved the highest grading possible in the British Standard of Mechanical Tests for 'hinged or pivoted doors':
Severe Duty - Subject to frequent or violent usage.
