TOP TRACK
The top track supports the weight of the door and is formed from heavy gauge cold rolled steel strip. It is fixed to the lintel with fabricated mild steel brackets where required and is galvanised or painted depending on the installation specification and size.
PICKETS
Pickets are formed from galvanised cold rolled steel and
from the main framework for the door on the inside of the building. The top of each picket is supported from the
top track with a hardened steel, grease sealed, multi-ball roller. The bottom of each picket runs within the
bottom track and gives the door its immense strength within high winds.
LEAVES
The leaves, which are 230mm (9”) wide, are formed from cold rolled galvanised steel strip and are ribbed for aesthetic purposes and extra strength. The gauge varies to suit the size of the door.
Options
In most cases the leaves can be supplied with Colorcoat
HP200 plastisol or polyester powder coating in a variety of colours. Windows are also available.
HINGE STRIP
The hinge strip is a capped cold rolled galvanised steel
outer channel, which allows the leaves to hinge vertically and move with the
picket section when the door is operated.
LATTICE
The lattice is a unique shape for extra strength and is formed from heavy gauge cold rolled galvanised steel strip. The lattice is bolted onto the pickets and controls the sideways movement of the door and prevents the door flattening out in high winds.
BOTTOM TRACK
The standard bottom track,
which is set into the floor, is manufactured from heavy gauge cold rolled steel
strip and runs the full length of the door.
LEADING EDGE
The leading edge stiffens
up the front of each door and is suitable for accommodating hasp and staples,
locks and handles It is formed into a
deep channel from heavy gauge galvanised steel strip.
SOFFITS & SIDE CLOSURES
Heavy gauge galvanised steel strip is press braked to the required size and shape and fixed to the doors and door jambs to give maximum security.
HARDWARE
Each door has a bow handle inside and out and is fitted with a heavy duty hasp and staple, which is normally fixed to the inside unless otherwise specified. The hasp and staple is supplied to take the customer’s own padlock.
ELECTRICAL OPERATION
Electrical operation is by means of a 415v three phase geared electric motor with open/close/stop controlled from a push button starter panel, and a manual disconnection device to enable the door to be operated manually in the event of a power failure or emergency. Each motor unit has integral limits that stop the door at each end of its travel.
Options
A variety of automatic, remote control and safety facilities are available. 240v single phase operation may also be available depending on the size of door.
