| STANDARD SPECIFICATION Gate
Frame
Eurofold's extra strength is gained
from the gate frame which is formed from unique double
channel vertical pickets
made from galvanised steel, 1.2mm thick. These are interconnected
by 2mm thick galvanised cold formed lattice bars. The gate frame is top hung from a ball bearing pulley connected
to the picket by zinc plated pulley brackets. At the bottom,
the frame is fitted with zinc plated bottom guide pieces
designed to run in a bottom track. Leading Edge
Roll-formed galvanised steel 117mm wide prepared for locks,
latches or interlock beaks. Number 10 bow handles are fitted
as standard. Shutter Leaves
The shutter leaves are rolled from galvanised steel and
are available in the standard width of 152mm with 102, 229
and 305mm versions also available. Top Track
The standard top track from which the shutter is suspended
is constructed from two galvanised steel sections 90mm deep,
bolted together to give a strong smooth running section for
the shutter thus minimising friction. Only a small amount
of headroom is required for the top track and variable packing
is provided to allow adjustment in height during longer term
service requirements. Bottom Track
The bottom guide pieces are retained within a 25 x 25mm
galvanised steel channel bottom track. Fire Resistance
Landing doors are supplied in a fire-resisting version when
specified. The door has been tested to BS 476 Part 22 1987
for up to four hours fire resistance.
