RS4 Extruded Slat Roller Shutter

Secure at night, invisible by day, with slotted holes for see-through visibility, ventilation and temperature control.

Why should I choose the RS4 security system for my business ?

  • Unobtrusive Side Guide Dimensions

    The RS4 system allows the shutters to roll totally from view leaving your doorways, entrances and throughways unobstructed when you want them to be.
    It also has the advantage of see through visibility with the manufacture of triangular slotted vision holes on the aluminium slats. This allows your stock to be visible at night when your business is locked and closed.

    In addition holes provide ventilation which has the advantage of reducing temperatures and preserving fresh goods more effectively. Slotted holes can also be manufactured between the slats.

  • Strength
     The RS4 Permashield Roller Shutter Security System comprises a curtain of interlocking extruded aluminium slats forming a solid security barrier.

  • Easy to Use

    The RS4 can be controlled manually or electronically. A key locking mechanism is an optional extra.

  • Wide range of Colours

    The RS4 has good visual appeal since it is powder coated in a wide range of high gloss finishes.
