FIRE RATED STEEL DOOR
FIRE RATED STEEL DOOR
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
acoustic 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 out pace
other manufacturers in this field.

Duodex Fire Steel Door are design to withstand 4 hour fire rating.
Installed in compartments areas to separate different zoning
areas. Areas which usually use steel doors are shopping
complexes, offices and factories. These doors have been tested
at Warrington, United Kingdom. The maximum size allowed is 3m
x 3m.

minimum 1.0mm thick mild steel plates. These are then finished
with primer.

The door selector is only applicable on double leaf doors and is
installed at one side of the door leaf. Door selector is used to
ensure that the door leaf without the lockset will close first to
ensure both door leaves will close properly.

installed to prevent the door from being dented.

fire performance of the doorset, these limit are: -
