Shutter
curtains

are
manufactured using traditional 75mm deep scrolled
interlocking lath, the gauge of which is determined
by the size of the shutter. Lath are galvanised as
standard to BS EN 10142: 1991: SEP02 G. Alternative
lath are steel end locked to prevent lateral
movement in the guide rails. A bottom rail of
heavier gauge material is used to strengthen the
curtain assembly and to form part of the drop bar
arrangement on manual shutters. CURTAIN FINISH

BS or RAL colours.

ROLLER
BARRELS
|
|
electronically
welded (ERW) steel tubes are used, of varying
diameter and wall thickness, which is determined to
keep the deflection of the barrel within Door and
Shutter Manufacturers Association guidelines.
Individually calculated counterbalance springs* are
inserted into the barrel. The spring anchors and
gearing used in Indupart roller shutter doors are
all of STEEL construction. Geared hand chain or
geared motor doors are driven using a drive chain
system** OPERATION OPTIONS Fire shutters are
provided to prevent flame spread from one
compartment to another, they are NOT for security.
If you need to use a fire shutter as a security
shutter Indupart recommend electrical operation.
*Electrically
operated fire shutters are not sprung
**
The pitch of the drive chain is determined by the
weight of the door and is calculated using 4-1
safety factor.

are cold
rolled "U" section channels. The channels
are assembled on fixing angles of suitable gauge to
suit the installation with the end plate being
pre-assembled on the guide angle, this helps
compensate for uneven fixing surfaces and speeds the
installation process up considerably (Flag guide
arrangement). A double guide arrangement is used on
manual doors to cater for the drop bar. GUIDE
RAIL OPTIONS Polyester powder coated finish to a
range of BS or RAL colours. (Grey primer standard).

Indupart fire shutters come with a canopy &
flame trap fascia system to ensure the maximum flame
spread prevention from your door, whether it is 1/2,
1, 2 or 4 hour rated. ACTIVATION OPTIONS - in
fire situations it is important that the shutter
closes to contain flame spread. There are different
modes of activation to close the shutter such as:
Standard thermal fusible link. Or if you wish the
shutter to be linked into a fire alarm: Thermo
electrical link, Resetable solenoid systems, Door
driven down under power in an alarm situation*. OTHER
OPTIONS - as well as the options stated in our
specification Indupart can offer a wide range of
options: Audio visual warning systems - these
warn the public that the shutter is going to close
before a time delay triggers the closure of the
door: Control descent devices - which control the
rate of fall of the door in auto close situation:
And a range of safety & other options.
* To
have one of these type of systems you must ensure
that there is a protected power feed to the shutter
motor.
