Sectional Overhead Doors
Designed and built to your specific requirements our Sectional Overhead Doors are widely used where a high degree of insulation is required. Various track arrangements can be provided to suit each individual application, dependant on available headroom
The
door panels are constructed from galvanised steel sheets, bonded together
with high density CFC free polyurethane foam to provide a 'U' value of
0.45W/m2K with a thermal break at each joint.
Vertical and horizontal tracks, hinges, brackets, side capping and hardware
are galvanised, with the assembled door running on adjustable galvanised
roller carriers bolted to each individual panel. The door is balanced
by means of helical springs at high level, mounted on galvanised steel
plates and quality bearings to give smooth and quiet operation. Cable
breakage devices are fitted as standard to prevent the uncontrolled dropping
of the door. Rubber seals are fitted to the top, bottom and both sides
of the door for good protection against weather. The internal face of
the door is bright white and the external face is available in a wide
range of finishes and colours.

double reduction gearing or by means of push up & pull down. Electrical
operation is by means of high quality three phase motor and gearbox. All
control panels are low voltage and have open, close and emergency stop
buttons as standard.Emergency manual over ride is provided as standard
to allow operation of the door in case of power failure.
