CURTAIN
The shutter curtain is constructed from ribbed galvanised
steel sections designed to provide 85mm deep, twin skinned hollow interlocking
laths with a thermal in-fill material.
The heat loss / ‘U’ value for the lath is approximately 0.69 W/m²K. As standard, hardwearing nylon endlocks are
riveted to both ends of each lath to prevent lateral movement.
Options
In most cases, the following lath options are available for
either or both skins: Colorcoat HP200 plastisol coating; polyester powder
coating; aluminium and stainless steel. Purpose designed double glazed vision
panel(s) are also available.
CURTAIN GUIDES
The vertical curtain guides are constructed from rolled
galvanised steel channels mounted on continuous mild steel angles for fixing to
the jambs. The channel is designed to
accommodate either the standard nylon endlock or cast aluminium security / wind
anchor endlocks.
BOTTOM RAIL
The bottom lath of the shutter is terminated with a steel
‘U’ channel and retainer with rubber weather seal.
BRUSH SEALS
Specially designed vertical brush strips are fitted to both
the inner and outer face of the guides.
A nylon brush strip is provided to bridge the gap between the soffit and
shutter curtain.
BARREL ASSEMBLY
The barrel, which is usually fixed behind the lintel, is
constructed from mild steel tube of sufficient diameter and wall thickness to
withstand deflection and twist during operation. Counter balancing is achieved by helical torsion springs mounted
on a steel shaft incorporated within the barrel and greased on assembly. Spring and shaft supports are cast iron.
SUPPORTING BRACKETS
Supporting brackets are
constructed from mild steel plate mounted on mild steel angle cleats for fixing
to the lintel and are of appropriate size and thickness for the weight and
dimensions of the door. Cast iron or
welded steel cups are fixed to the end plates to receive the barrel’s centre
shaft.
HOOD, FASCIA AND SOFFIT
A galvanised sheet steel
hood can be supplied to enclose the barrel assembly. Alternatively a sheet steel fascia can be supplied to fill the
soffit. Other finishes may be available
to match the curtain.
LOCKING ARRANGEMENTS
As standard, electrically operated doors are secured through
the motor drive gearbox, when not in operation.
Options
Guide locks, high security
ground locks or shoot bolts to receive a customer’s own padlock can be fitted
for additional security. Electrical
interlock devices are available to prevent electrical operation whilst locks are
still in place.
ELECTRICAL OPERATION
Electrical operation is by means of a 415v three phase
flange mounted motor with integral limit switches to control travel of the
shutter curtain and open/close/stop controlled from a push button starter
panel. A manual override device allows
operation in the event of a power failure.
Options
A variety of automatic, remote control and safety facilities
are available. 240v single phase
operation is also available depending on size of door.
