Manufactured to International Standards


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. The roller tube is adequate for the door dimension and will have a deflection ratio of less than 400:1.



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 SR2-4 Terror Screen doors or our unique Typhoon security shutter.


The door curtain is formed from 73mm convex steel galvanised interlocking steel roller shutter laths retained at ends via end locks. Solid or perforated sections.

The bottom rail is a “T” section interlocking section with optional rubber seal. The curtain is available in plastisol or powder coat finish to standard colours, larger sizes may need to be wet coat finished.


  • Manually operated slip bolts on the bottom rail or pin locks on the guide, manually interlocked to the control panel to prevent accidental operation.
  • Electrically operated by press button when the door is closed
  • Fully automated.
  • Optional Monitoring and signalling of lock status.

Size Guides

Fabricated from steel continuous angle and steel guide channel in galvanised finish and bolted at fixed centres to an appropriate structure. The guides optionally are available in power coat finish.


Optional hood, motor hood, flashings in galvanised steel materials or in powder coat. Stainless steel options also available.


The door can be press button operated or automatically operated. Various levels of safety can be fitted including safe leading edge and or photocells movement sensors and so on. Controls should be mounted at least 1m from the door structure.


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.
