Hart has supplied hundreds of industrial doors to infrastructure projects both across the UK and internationally.
Depending on door size the motor drive is constructed using either Safedrive direct drive or via chain drive and reduction gearing supported via a safety brake. Very large sizes may also have internal counterbalance springs to reduce operating loads and minimise the drive requirements.
Doors are available from 1.2 metre wide to 9 metres wide and up to 9 metres high. All doors are made to measure to specific requirements. For a higher security rating or extreme wind conditions we recommend the SR4 Terror Screen doors or our unique Typhoon security shutter.
Roller shutter door electrically operated utilising a steel twin skin door curtain of twin interlocking optionally insulated roller shutter section. The construction of the door curtain is 35Kg’s per square meter and it runs within side guides of fabricated steel
The door curtain is finished at floor level with a structural bottom beam fabricated from steel and aluminium sections and optionally finished by rubber seal. Available up to 9m without need for locking at the centre of the rail.
The door can be press button operated or automatically operated. Various levels of safety can be incorporated which are obligatory if automated operation is required, including safe leading edge and or photocells movement sensors Radar, radio and so on. Controls should be mounted at least 1m from the door structure, unless additional features are added
Structural opening substrate must be suitably reinforced brickwork/concrete/steelwork as detailed in the standard LPS1175 Issue 7. It is assumed that the substrate onto which the product is fitted provides a resistance to attack at least equivalent to that afforded by the product itself.
Standard opening Speed: 0.15 m/s
Standard Closing Speed: 0.15 m/s
