Duodex fire rated steel doors, tested at Warrington U.K., are 2 hour and 4 hour rated. Our Fire rated steel door come in single leaf and double leaf.
Our Fire rated steel Doors have received the unique acceptance from Warrington, UK, that permit our doors to be used and fixed with ten (10) different types of locksets approved for fire resisting steel doors.
This comes in a mixture of cylindical locks and mortise locks. A glass panel is allowed in the door for viewing purposes. The fire rating of different types of glass effects the fire rating of the door.
These fire doors are uninsulated in nature. To increase the insulation, rockwool infill will be added. This will also increase the accoustic capability of the door.
Where stainless steel frames are required, the gap between the mild steel door leaves and the stainless steel frames must be increased to 4mm. Where both are stainless steel door leaves and door frames, the door configuration must be consistent to give a balanced assembly.
These fire rated steel doors can be manufactured to a maximum size of 3.0m(L) x 3.0m(H). It is an accomplishment that outpace other manufacturers in this field.
