Overhead sectional doors are ideal in situations where headroom may be restricted, and there is insufficient space to fit the box required for a roller shutter. This type of door slides upwards on side runners, which continue onto the roof area so that aperture space is maximized when the door is in the open position. With insulating and sound-reducing qualities, our overhead sectional doors lend themselves to a wide range of industrial and commercial environments. A foam core between the inner and outer steel sheets of the door panels prevents transmission of heat or cold, delivering a thermal performance which exceeds building regulations. These high-quality doors are extremely robust and constructed to give long service. In the event that a door incurs accidental damage, it can be easily repaired using replacement components.
Ideal uses / application
Curtain : The curtain is constructed from galvanised continuously interlocked steel laths that are securely held in place by end locks. A number of thicknesses and profiles are available according to individual circumstances such as size, wind loading etc. Bottom rails are generally galvanised and roll-formed into a tee section.Guides : Vertical guides are formed from rolled steel or fabricated dependent on size and are supplied with appropriate angles for fixing to the structure.Endplates : Mild steel of appropriate thickness in relation to door thickness is prime painted and supplied with angles for fixing to he structure.Barrel : Our barrels are normally made from a seamless steel tube of adequate diameter to counteract deflection and hold in bearings or cups attached to the endplates.Finish : Comes galvanized with non-galvanized parts prime painted as standard. Customers can choose to have a powder coating of almost any color as an additional extra.Operation : Shutters over smaller openings are typically powered by a 240-volt single phase tubular motor whereas larger shutters are operated using a 400-volt 3 phase geared motor. Adjustable limit switches are incorporated to stop the shutter at the end of each travel. Standard controls include open/close/stop buttons for geared motors and rocker switches on single phase tubular motors.
