| STANDARD SPECIFICATION Door
Leaves
The doors can be manufactured as singles or pairs. The door leaves are constructed from 1.2mm thick zinc coated
steel sheets folded to form a 45mm thick panel with the vertical
edges reinforced to increase panel strength and rigidity.
Horizontal channels are welded to the inside of the sheets
to close off the top and bottom of the leaf. The panels are normally infilled with a bonded honeycomb
core but can be infilled with rockwool for increased thermal
insulation. Reinforcing pads are fitted within the leaf to
accept hardware fixings. The hinging edge is reinforced with steel mounting plates
and the lock body is fitted within an internal closure for
ease of maintenance/replacement. An overlapping steel astragal is fitted on a pair to ensure
positive sealing. Frame
Supplied in knockdown form for ease of handling/installation,
the frames are constructed from 1.6mm thick zinc coated steel
to form a single or double rebate profile.
Headers are butt-jointed to the uprights
and are reinforced to accommodate the fixing of door closers.
Uprights are reinforced
with steel plates at hinge and lock positions.
Frames can be supplied as a first-fix
built-in arrangement or prepared for bolt-fixing to the structure. Hardware
Our standard stainless steel ball bearing hinges are included
with other hardware items to suit clients' individual requirements.
A standard range of hardware is kept in stock to ensure that
clients' delivery requirements are met since some specialist
hardware items can be on extended lead times. Finish
As standard, all doors/frames are factory primed for painting
on site (by others) after installation.
