Why Trellidor Rollerstyle Lockdown Shutter is a First for South Africa

The Trellidor Rollerstyle Lockdown Shutter is a first for South Africa because unlike other security roller shutters, it does not rely on a locked motor, shot bolts or locks with keys to keep it in place once shut. Instead, it has a non-mechanical system that prevents the shutter being lifted once rolled down into position. This high security roller shutter door locks so firmly into place that even a forklift can’t budge it.


Trellidor rollerstyle lockdown shutter features

The Trellidor Lockdown Shutter looks like other roller shutters, with rows of aluminium slats that roll up and down inside guide channels set into the walls. But where it differs is that the Lockdown roller shutter design has some specialised features that set it apart from the rest.

These features make the Trellidor aluminium roller shutter door one of the strongest on the market. It is engineered to protect high value items from theft or attempted break-ins at premises that stock merchandise frequently targeted by criminals, for example, cigarettes and alcohol.

The security roller shutters unique features are:

  • There is an Actuator between every slat. The entire curtain is made up of alternating S-shaped actuators & double-wall slats.
  • The Actuators translate any irregular vertical force (such as that of an attempted breach) into horizontal forces. This firmly pushes the entire curtain against a set of guide rubbers on both sides. The multitude of contact points serve to maximise frictional force, which ‘locks down’ the curtain.
  • In the lockdown position, the roller shutter door is virtually impossible to lift up, even if the motor malfunctions.
  • For safety reasons, the rollerstyle roller shutter can be fitted with an easy-to-use manual override system.
  • The Lockdown Shutter is custom-made and designed to fit doorways and windows.
  • Guide channels specially engineered for this roller shutter can be recessed into the surrounding substrate for increased security and a neat fit.
  • The rollerstyle shutter has no floor channel so there is no tripping hazard.
  • A double walled slat system makes it an extraordinarily strong aluminium roller shutter and assists with heat control when the shutter is closed.
  • Automated roller shutters can be conveniently operated using a remote control.


Lockdown shutter safety features

The security roller shutter curtain is virtually impossible to open from the outside once it is locked down. The only way to raise the curtain is by using the remote control to engage the motor or by using the manual override system.

To prevent accidental locking, the shutters are fitted with an obstacle detection system. There is also an easy-to-use manual override crank handle, provided for emergency opening, such as during a power outage.

This crank handle can be removed and stored near the shutter for use during an emergency. The crank handle simply clips magnetically into position when required. In South African conditions, where power outages are frequent, either planned or accidental, this is a critical safety feature.
