Kingspan 610 mm deep x 40 mm thick composite panels manufactured using 0.5 thick hot dipped zinc coated (to BS EN 10147) steel internal and external facing sheets. These sheets are bonded together using a CFC free foam which has a density of 40kg/m3. Each Panel has a formed tongue and grooved hinged joint incorporating a neoprene seal running the full length of the panel to give excellent weather resistance. The panel itself gives a “U” value of 0.45 W/m2 K, meaning that a typical 4,000 x 3,500 (W x H) door fitted and tested gives a “U” value of 0.9 W/m2 K when installed.
Stucco embossed and Plastisol coating to a standard colour to external face with White to internal face. Extruded aluminium cappings are fitted to the top and bottom panels, these are fitted with rubber seals and combine with the vertical PVC side seals to provide an effective perimeter weather seal
Sectional doors are counterbalanced to ensure the smooth running of doors, using minimal effort. All counterbalance spring calculations carried out, are done to get the maximum life out of the door springs we manufacture. The springs are manufactured using high tensile helical wound steel, these are heat treated for improved performance. The springs are mounted onto a steel shaft supported by bearing brackets incorporating sealed bearing rollers, this ensures free running of the shaft. Also mounted on the spring shaft are the cable drums, these carry the aircraft quality lifting cables. These are looped and swaged using a hydraulic press to ensure the cables do not get detached from the cable drums or the brackets which connect the cables to the bottom of the door panels
The roller carriers are adjustable to allow the door panels to seal perfectly against the door seals and along with the intermediate panel hinges, are hot dipped galvanised steel. The rollers which run in the vertical side track are sealed for life, self lubricating bearings c/w a nylon tyre, to give a smooth and quiet operation. The rollers are mounted onto a zinc plated steel shaft.
The door track systems are designed to suit the headroom available above the opening and where necessary, the pitch of the roof. Manufactured using pre-galvanised 2mm formed ‘J’ style track, mounted to a continuous galvanised jamb angle incorporating vertical PVC side seals to ensure positive sealing
As the name implies, are designed when there is limited headroom available. This places the spring assembly to the Rear of the horizontal tracks to maximise the headroom available.
Also available pitched to follow the contour of the roof. When there is sufficient room in height and projection into the building
Also available pitched to follow the line of the roof. Manufactured when there is little restriction in height but possible projection into the building i.e.
Services/lighting/overhead cranes. Maximises space for taller buildings
When there is sufficient height in the building to eliminate any projection
