Sectional Overhead Doors

Application

Each door is purpose made to suit site dimensions and requirements and is suitable for all types of industrial use where a high degree of insulation is important. Various track arrangements can be provided to suit each individual application, dependant on available headroom.

Technical Specification

The door panels are constructed from galvanised steel sheets, bonded together with high density CFC free polyurethane foam to provide a 'U' value of 0.4W/m2K with a thermal break at each joint. Vertical and horizontal tracks, hinges, brackets, cappings and hardware are galvanised, with the assembled door running on adjustable galvanised roller carriers, bolted to each individual panel.

The door is perfectly balanced by means of helical springs at high level, mounted on galvanised steel plates and quality bearings to give smooth and quiet operation. 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.

Operation

Manual operation is by means of a continuous galvanised haul chain, through single or double reduction gearing or by means of push up/pull down. All manually operated doors are fitted with a recessed lifting handle and an internal shoot bolt lock.

Electrical operation is by means of a high quality, 3 phase motor and gearbox, incorporating 6 integral limits. All controls are low voltage and have open, close and emergency stop buttons as standard. Emergency manual override is provided as standard, to allow operation of the door in case of power failure.
