| STANDARD SPECIFICATION Gate Frame
Extra strength is gained from the 25mm hot rolled channel
pickets interconnected by 30 x l0mm solid steel lattice
bars. The gate frame is top hung from free running ball
bearing pulleys connected to the pickets with zinc plated
bottom guide pieces fitted at the base to run in the
bottom track. Leading Edge
The high security leading edge is fabricated from steel plate
and channels into a rigid box section into which a safety
edge is fitted to stop the door should it meet an obstruction.
Shutter Leaves
305mm wide x 1.2mm or 1.5mm thick galvanised steel, the leaves
are formed in a unique detail around 3mm diameter strengthening
wire to provide a continuously interlocking weather tight
installation completed by securely capped galvanised steel
hinge strips. Top Track
The 229mm deep fabricated top track incorporates two round
edge runner rails ensuring smooth running of the pulleys.
The motor gearbox, tensioner and adjustable limits are
surface mounted for ease of access whilst the drive chain
is totally enclosed to provide direct in-line transmission.
Bottom Track
Type B24 fabricated from double 51mm x 25mm hot rolled steel
channels which finish flush with the floor. Cover Plate
A galvanised steel cover plate is bolted to the top track
to act as a flashing over the shutter leaves. End Panels
Galvanised steel end panels can be provided to act as a vertical
closure when the doors fit behind the opening.
Fixings
All shutters are provided with the appropriate fixing bolts
for attachment to the opening structure. Shutter Arrangements
The doors can be supplied to fix externally, internally or
between jambs and can bunch to one or both sides of the
opening.
