PVC & Rubber 'Crash' Doors
Flexible crash doors are the most practical and economical
solution to heat loss and noise pollution in the workplace. With the
correct panel and frame selection, flexible crash doors can provide a
low maintenance, low cost, answer to reducing the waste of energy that
occurs in un-enclosed areas without affecting speed of movement through
these openings.
Flexible crash doors are widely used in the following applications:
 Retail
units and supermarkets
Food preparation
areas
Hospitals
Coldstores and
cleanrooms
Warehouses
Industrial units
and factories
Postal sorting
offices
Flexible doors are favoured in these environments due to
their durability, ease of use, minimal maintenance and the concealed
spring unit mechanism. A range of finishes to the door framework is available
to suit different environments. These include powder coating, electro-zinc
plating and standard paint finishes. Doors with stainless steel framework
are also available.
Door Framework
The four framework types shown below range from light to
heavy duty. The Superflex, Multiflex and Interflex frames house a vertical
spring unit mechanism in the top of each door tube. The Powerflex frame
houses a unit in the top and the bottom of each tube. The mechanism is
a double action, adjustable tension, torsioned spring unit concealed
in the doorframe and is virtually maintenance free. The panels shown
in the frames below are suggestions only - for the full range of panel
options see the Door Panels section below.
 Superflex
Manufactured from high quality extruded aluminium
section, that has smooth lines and no projections. Used frequently
within the food industry this is a lighter duty door than
others in the range and has the panel fixings concealed within
the framework. Suitable for use on internal openings with
pedestrian, hand or light powered traffic on openings up
to 2400mm wide x 2438mm high.
 Multiflex
Manufactured from 43mm o/d heavy wall mild
steel steam tube, with a horizontal gusset plate and vertical
mild steel flats to hold the panel in position. Suitable
for use in many applications, dependent on panel choice.
They are ideal for internal
openings but can be used on semi-external/external openings dependent
on site conditions. They allow access by pedestrian, hand or powered
traffic on openings up to 2400mm wide x 2600mm high.
 Interflex
Manufactured from 60mm o/d heavy wall mild
steel steam tube, with a horizontal gusset plate and vertical
mild steel flats to hold the panel in position. Suitable
for semi-external/external openings dependent on site conditions,
for use by pedestrian and powered traffic. Offering a heavier
duty construction than the Multiflex and Superflex these
doors are suitable for use on openings up to 3000mm wide
x 3350mm high. NB. On openings above 2600mm wide the triangular
gusset plates will be replaced by horizontal top tubes.
 Powerflex
Manufactured from 60mm o/d heavy wall mild
steel steam tube with a horizontal top tube, vertical mild
steel flats and a corner gusset plate to hold the panels
in position. Suitable for heavy duty external applications,
with powered traffic. Powerflex doors are suitable on openings
up to 4000mm wide x 4000mm high and many extras are available
to increase the specification on the door framework and panels.
i.e. horizontal spring unit mechanisms, dome disc protection
studs, wearpads, increased overlap, larger clamping flats
etc. NB. On doors below 2600mm wide the horizontal top tubes
will be replaced by triangular horizontal gusset plates. |
Door Panels
Choosing the correct door panel type can extend the lifespan
of your flexible crash doors. The panels shown below are available in
new doors and can also be supplied as replacements for existing crash
doors.
PVC colours available: black, grey, white, blue, red.
(Please note maximum size available on grey/white/blue/red panels is 1200mm
wide per panel)

Automatic Doors
Flexible doors of all specifications can be operated automatically
where desired. They are often used when an optimum flow of traffic is
required, for example in a busy warehouse or production area.
Flexible doors are modified for automatic operation in
one direction. The direction must be specified prior to order, but the
doors are able to swing in both directions manually. Flexible doors can
be automated either Pneumatically (air) or Electrically.
Quotation Requirements
It is important to provide the correct details for quotation
and subsequent manufacturing purposes, because the correct specification
can extend the life expectancy of your flexible doors. The following
details are required:
Structural opening
The exact structural opening width, measured at the top, middle and bottom
and the exact opening height at the left, the middle and the right hand side,
are required to allow for manufacturing tolerances i.e. if the opening is
not square.
Fitting arrangement
Standard fitting arrangements allow fitting to the underside of the lintel
and to the floor, please state the composition, i.e. timber, steel or concrete,
that the lintel and floor are made from. Fixing plates can be supplied to
enable fitting to the jambs if required, i.e. if there is no lintel or if
the floor is uneven, please state the composition of the jambs.
Traffic
Specify what type of traffic is using the opening so that the right specification
can be offered, i.e. pedestrians, hand powered trolleys, fork lift trucks,
etc. Note: it is recommended that the width of the doors should be a minimum
of one and a half times the width of the traffic, if this is not possible
then automatic flexible doors are recommended.
Situation
Location of the doors, i.e. internal or external and whether the doors are
subject to wind pressures.
Environment
The environment that the doors are going into, i.e. warehouse, coldroom, wash
down area etc. in order that the correct specification of finish to the door
framework can be offered, i.e. powder coated, electro-zinc plated etc.
