Roller Shutter Doors
Roller shutter doors are without doubt the most popular type
of door. Different fixing arrangements allow roller shutters
to be installed in many ways. The total weight of the door is
carried by the side piers, no special steel or lintel is required.
Installation is quick and easy. When in position the small amount
of space occupied is well away from any vehicles. When repair
is necessary the interlocking curtain sections enable remedial
work to be carried out quickly and economically.
These roller shutter doors are built to withstand the toughest
conditions giving the user the reliability they need whilst
retaining ease of operation. The best materials are used and
the highest standards of quality are maintained and through
continual development and research we have engineered our rolling
shutter without sacrificing specification, so that this door
offers value enqualled by any other.
Type of doors
Generally, roller shutter doors have two broad classifications:
'Commercial' - comprising of manual self coiling
'push up push down' and electric single phase tubular motor
doors.
'Industrial' - comprising of manual hand chain
and electric three phase power operated doors.
Our commercial roller shutter doors are used in many varied
locations ranging from offices, shops and schools, to high street
retail chain stores. They provide an ideal security solution
to shop front entrances, windows, doorways, bar counters, servery
hatches, garages and other high risk situations.
Manually operated 'push up/push down'
self coiling roller shutter doors
An economic roller shutter door, which is ideal for smaller
apertures where the door will be opened/closed a limited number
of times each day. The curtain of the door is manually raised,
assisted by counterbalancing springs within the roller barrel
assembly. Mild steel 'flag-post design assemblies are fixed
vertically to the structure surrounding the aperture to support
the roller barrel assembly onto which the roller shutter curtain
is secured. The maximum recommended size of this type of door
is 3800mm wide x 3800mm high.
Industral Shutters
Our industrial roller shutter doors are used by many
household named multi-national operations as well as sole traders
alike. They provide access and security solutions to loading
bays, goods inwards stores, car park entrances and many other
'high usage' locations.
Electrically operated 'industrial'
roller shutter doors
Ideally suited for industrial applications that require
frequent usage. All door components are identical to that of
the manually operated 'hand chain' roller shutter door, except
for the door being raised automatically bya 3 phase 415 volt
electric motor in lieu of the hand chain wheel drive mechanism.
The standard actuation method is via an up, down and stop push
button station. A manual overide continuous haul chain is provided
for use in the event of a power failure. A single phase 240
volt option is available where site condition, ditate. |

'FUJIKAWA' Fire-rated Shutters are
suitable for use in commercial or residential opening of up
to 10m wide by 7m high in a single panel. It employs the same
design concept and components as the Roller Door, except for
the curtain material, which consists of 75mm x 19mm or 100mm
x 25mm galvanized steel inter-locking slats. The thickness of
the slats, which ranges from 1.0mm to 1.2mm determines the fire
rating of the roller shutter.
Custom designed scrolled profile roll-formed from 1.0mm to 1.2mm
thick galvanized steel with iron end clips to prevent lateral
movements. The curtain was fixed to the barrel through the top
slat by eight M10 bolts with 30 x 30 x 1.5mm washers under the
bolt head. The bolts were evenly spaced along the slat at nominal
300mm centers with the first bolt approximately 165mm from the
end of the slat.
During the test, the concave surface of the slats was exposed
to the fire. |

21 Steel Roller Shutter are suitable for use in commercial
or residential. The curtain shall be of interlocking colorbond
steel slats having a thickness of not less than 0.6mm and
secured on every alternative slat with a nylon endclip. Roller
shutters shall be complete with not less than 3mm wall thickness
roller drum, solid shaft, helical torsion springs, aluminium
bottom rail, galvanised or aluminium guide track and all operating
gear.
Hand operation: For smaller shutters, which are counter-balanced
by springs to offer an ease of operation. Chain operation
: Is by a heavy duty hand winder with a ratio of 4:1. This
system uses the same bracket, spocket and drive chain as our
motorised shutter making motorisation at a later date a simple
and very cost effective procedure. Motorised : Is by a purpose
built shutter drive including emergency manual chain override
in case of power failure, available in 240v or standard in
3 phase and can be coupled with logic controls, fire alarms
etc.

"21" Perforated Shutters
are suitable for use in commercial or residential openings of
up to 3.5m wide by 3m high in a single panel. For larger openings,
it can be operated by dividing into 2 panels or motor driven.
It employs the same design concept and components as the Roller
Door, except for the curtain material, which consists of 75mm
x 19mm x 0.8mm thick zincalume or stainless steel inter-locking
slats with self-locking system. The entire concave portion of
these slats contains 3mm diameter perforations spaced at 2.5mm
staggered pitch which gives excellent airflow and light exposure
through a total perforated surface area of approximately 50%.
This results in a roller shutter door with a "see-through"
effect which also offers excellent ventilation and at the same
time, prevents the wind-load force acting fully on the door.
It is therefore preferred over the conventional method of punching
slots through the slats for ventilation. To avoid weakening
the interlocking joints, the scroll edges of the slats are not
perforated.
"21" Perforated Shutters are recommended to be powder-coated
as the coating thickness of 25 microns effectively covers the
burrs of the perforated edges, smoothening out any sharp edges.
Powder-coating also offers greater flexibility in colour choice.
It is an advantage greatly appreciated by most of today's Architects. |

The curtain is designed for commercial and residential
use. Available in both manual and automatic models, these doors
are suitable for openings up to 6m wide x 6m high in a single
panel. For wider openings or if desired, a series of smaller
width doors can be fitted, linked by removable centre mullions.
Roller Doors are made up of 0.579mm thick Hi-Tensile's Colourbond
steel, each slat is nominal 75mm pitch. Tensile's colourbond
steel coating system consisting of Zincalium (45% high tensile
steel, 50% alloy and 5% silicone), strength 432 N/mm
and finished with oven-bakes silicone modified polyester coating. |

"21" Aluminium Shutters
are designed for commercial or residential openings of up to
6m wide by 6m high in a single panel. It employs the same design
concept and components as the Roller Door, except for the curtain
material which consists of 75mm x 1.5mm thick aluminium interlocking
slats with self-locking system. It is available in 3 different
models. "PLAIN" which consists of plain aluminium
slats. "WIND-HOLED" which consists of slats perforated
with 100mm x 25mm slats spaced at 200mm apart to achieve a lattice
grille appearance. "VISION" which consists of slats
perforated as previously described but with 1.5mm thick clear
polycarbonate strips secured to the back of the slats to achieve
a glazed effect. These three slats type can also be used a a
combination in a single shutter to achieve a particularly architectural
effect or for practical application. The beveled edges of the
slats combine to form lateral V-grooves, which when viewed at
the front gives the shutter a clean sculptured appearance.
These shutters are available in natural anodized, powder-coated
or fluorocarbon coated to match desired color scheme. |
