SERIES 900
ONE PIECE SECTIONAL VERTICAL DOORS
|
This type of door is mostly used for light industries
operations, shipping and receiving areas or any other areas
where it is possible to install a vertical lift door. This type
of door eliminates the famous torsion springs breakages and
cables jumping the drums.
|
The doors are ONE PIECE SECTIONAL VERTICAL DOORS SERIES 900 as
manufactured by Dorion Doors Inc., 2987, boul. Perrot, Île
Perrot, Quebec, Canada J7V 8P4.
All doors are manufactured as per our shop drawings and
standardized specifications described below.
All doors are also manufactured as per CSA W47.1 certification
from the Canadian Welding Bureau.
|
The construction and use of this type of door are versatile. You
can use doors series 350 and 500 with preference to inside
covering sheets of .91 mm thick and outside covering sheets of
1.6 mm thick.
The doors are manufactured to withstand an overload due to the
wind of 1 kPa with less than 1/240 deflection in the horizontal
plane.
|
The insulation is a fire retardant polyurethane foam injected at
a density of 49 kg/meter³ (3.6 lbs/foot³) as per norm ASTM C-518
for thermal resistance and ASTM E-84 for flame spread at <25 and
smoke at <450. C.F.C. free.
For all heated buildings, it is highly recommended 100 mm thick
doors to save energy. These 100 mm thick doors pay themselves
year after year.
|
The counterweights box is manufactured from 1.6 mm thick Z275
galvanized steel sheets, sizes as per the door list, with a
minimum height of 2440 mm. The counterweights are in steel. The
counterweights are guided by cables all through their trajectory.
The box is designed to permit easy access without problem to the
counterweights for repairs if necessary.
|
Doors up to 150 kg will be guided in 50 mm tracks 2.4 mm thick.
Doors exceeding 150 kg will be guided in 75 mm tracks 2.8 mm
thick. The Z275 galvanized steel tracks are supplied with 11.43
cm x 3.81 cm x 2.8 mm thick continuous steel angle. The vertical
tracks are inclined.
|
COUNTERBALANCING MECHANISM:
|
The friction free drive mechanism consists of using three cable
drums (to the manufacturer's option) mounted on a solid cold
roll shaft. This 25 mm minimum cold roll shaft is secured to the
bearing plates with pillow blocks. Each counterweights set is
suspended from one pair of drums using two cables. The diameter
of the galvanized steel aircraft cables is in accordance with
the weight and the dimensions of the doors, 7 x 19 construction,
with a safety factor of 7:1.
|
The drums used will carry the door weight. Each door section is
joined together with 3.3 mm thick hinges independently of the
quality of the door. The top corner brackets will be
multisections safety corner brackets that will automatically
lock the door in the tracks and simultaneously cut the power to
the motor, if the door is electrically operated, in case of a
cable or roller chain parting. The heavy duty bottom corner
brackets are in galvanized steel. All hardware will be fastened
to the doors with 4 mm diameter galvanized steel rivets.
|
An aluminum extruded channel is fastened underneath the bottom
section in which slides the U-shaped santoprene weatherstrip.
The U-shaped santoprene can be replaced by an AGDS type safety
edge to serve as weatherstrip as well as safety when the doors
are electrically operated.
An aluminum extruded channel with a triple contact santoprene
weatherstrip is provided for the outside perimeter.
|
The doors are painted on both sides with one coat of 26 microns
epoxy primer and coat(s) of 48 microns acrylic/polyurethane
finish paint to obtain a certified thickness of 74 microns.
The colours are at the architect's choice.
