FIRE RATED DOOR

FIRE RATED DOOR is a fire
resisting roller shutter designed and
tested on both sides to guarantee an
integrity up to 1000 °C for 120 minutes
(E performance) and to keep the
thermal radiation below 15 kW/sqm
(W performance), in order to protect
people and goods in the proximity
from heat radiation generated by fire.
The mantle is composed of double-
sheet galvanized steel slats, with
insulation, height 114 mm, thickness
22 mm and weight of 30 kg/sqm.
The slats are securely hooked together
and fastened on the side with steel
end locks in order to prevent slipping
of the slats and to guarantee the
uniform mantle descent.
