DescriptionThe Swift SEW steel folding door system is a side hung, fast opening, insulated flat panel bi folding door model with electric operation as standard. Available as a 2+2 panel arrangement with maximum width of 5000mm and a height of 7000mm this door is specifically designed for taller openings and uses only one track for supporting the door leaves.
The door panels are double skinned and foam filled to offer acoustic and thermal insulation.
The steel panels are 62mm thick with a weight of 30kg per square metre.
The leaves are designed to fit to the inside face of an opening and then open to a 90 degree angle to provide the full drive through opening dimensions.
The side room required is between 290mm and 310mm and headroom is 450mm.
The door has an opening speed of 8 -10 seconds, using a three phase electric motor drive.
An emergency manual override is always supplied as standard.

The Swift SEW electric folding door is a made to measure door system as standard but always with the 2+2 door leaf arrangement and electric motor drive operation.
A flush steel goalpost surround frame should always be provided in order to install a Swift SEW folding door. The minimum thickness of material to be 6mm, and the width of the internal surface to be minimum 150mm. In addition a 300mm x 300mm motor mounting plate is required above the door at the centre of the opening. This can be supplied by Samson or the customer to suit the aperture build.
Key Features for Swift Folding Doors
■ Leaves always fold clear of the structural opening and require as little as 200 mm side room.
■ Minimal headroom of as little as 150 mm for low clearance openings.
■ Horizontal folding action provides full height access as the door moves.
■ UKAS laboratory tested to 110,000 continuous cycles without replacement of parts (equivalent to 15 cycles a day for 20 years).
■ No bottom track – leaving a clear threshold.
■ Full height pass doors or integral wicket doors can be incorporated within the main door.
■ Invisible protection zone around the door prevents doors impacting on people or vehicles.
SpecificationPanels are constructed from 2mm thick cold rolled galvanised dovetail channel frames with mitred and spot-welded joints and 5mm thick local reinforcement for hardware. The frame is covered on both sides with minimum 0.65mm thick steel sheets and pressure injected with 50kg/m3 CFC-free polyurethane foam to form an extremely strong, rigid, flat panel without mechanical fixings. Panel thickness is 62mm.

Threshold
140 x 10mm thick extruded aluminium plate with 30° chamfered edges is fixed directly to the ground with M6 x 75 Thunderbolts. This plate forms a water bar, presents a level surface for the folding door to seal against, minimises bottom seal wear as the door folds, and provides a solid location point for floor securing bolts.
Seals
Flexible rubber seals are fitted to all edges of the door, and between door leaves. All seals are purpose-designed EPDM extrusions, which press into, and blend seamlessly with the door panels. Each seal provides full finger trap safeguarding, and excellent protection against weather, dust and sand.
Tracking
Top tracks are 4 mm thick pressed galvanised steel supported with purpose designed hot-dipped galvanised steel track brackets for fixing back to the head steel. 4-wheel pendant trollies with Ø50 mm sealed bearing wheels and Ø16 mm shafts guide the doors at the head. Pendants are mounted in 80 mm x 120 mm machined and bushed extruded aluminium brackets. Pendants are vertically adjustable.
Windows
Aluminium window frame with one-piece inner liner tray. Window units are double glazed (4~20~4), argon filled, low E toughened glass. Frames are polyester powder coated in matt black to RAL 9005(M), fully sealed, and available in a choice of frame sizes as follows:
400mm x 600mm
600mm x 600mm
400mm x 1200mm
600mm x 1200mm
Locking Systems
An electro mechanical lock within the drive motor automatically holds the door in the closed position.
A stainless steel bottom guide pin engages with a yellow cast-aluminium floor shoe fitted to the threshold, and holds the leading edges in place.
A black thermoplastic easy-grip pull handle is fitted internally to each door leaf for manual operation of the door.
Option 1
A lever operated floor bolt is fitted internally between pairs of leaves and is electrically interlocked to prevent electric operation with the bolts engaged. The bolt comprises a 240 mm x 70 mm steel case with cast aluminium lever handle which throws a 30 mm x 10 mm steel bar into a stainless steel socket on the threshold. Floor bolt is finished in BZP.
Option 2
An automatic solenoid floor bolt is fitted internally between pairs of leaves. The bolt size is Ø20mm with a 50mm stroke and engages automatically into a floor socket as the door closes. The bolt comprises a 335 mm x 60 mm x 55mm black powder coated steel case. Optional cylinder for manual operation.
