Knightguard Visionline aluminium & polycarbonate roller shutters are suitable for commercial applications as shopfront shutters for shopping centres, retail outlets, shop windows, offices, warehouses, factories, cafes, restaurants, pubs, clubs, hotels, storage areas, store rooms, serveries, counters, bars, kitchens, kiosks and residential applications such as car ports, garage doors, verandahs, patios and other outdoor areas. They provide a great way of maximising limited space - by rolling up and out of the way they provide an unobstructed passageway when open.

The robust aluminium construction of the Knightguard range of roller shutters combined with Visionline's roller shutter curtain made from alternating durable polycarbonate slats interlinked with extruded aluminium connecting rods provides a robust construction while allowing vision through the roller shutter for visibility and light transmission.

The compact roll size means Knightguard Visionline will take up less space and be suitable for smaller openings or restricted headroom than comparable polycarbonate roller shutter products.

Knightguard Visionline roller shutters are easy to use and operate with both manual and a variety of electric control options available.

Advanced Shutter Industries has been a manufacturer of roller shutters and roller grilles since 1976 and continues to offer some of the best roller shutter products available in Australia today.

Knightguard commercial roller shutters and roller grilles are manufactured in our Belmore factory in Sydney NSW Australia and are available to be supplied to city & country areas in Brisbane QLD, Melbourne VIC, Hobart TAS, Adelaide SA, Perth WA, Darwin NT, Canberra ACT, and are also available for export outside of Australia.

Knightguard Visionline polycarbonate commercial roller shutters are simple to use and operate with a variety of manual and electric motor controlled lifting mechanisms available, giving you full control over your environment. Operation, opening and closing, locking and unlocking is customised to your needs so you choose how and where you want to open and close your Knightguard Visionline polycarbonate roller shutter, whether it is from the inside, outside, both inside and outside, via keylock, hasp and staple, electric key lock or radio remote control.

Electric Motor Roller Shutter Lifting Mechanism

The most convenient way to open and close roller shutters is to opt for the electric motor option. A range of electric tubular motors and accessories are available from Advanced Shutter Industries for roller shutters which includes:

  • 240V mains powered tubular electric motors for roller shutters operated by hand-held radio remote control
  • 240V mains powered tubular electric motors for roller shutters operated by a wall switch or keyed wall switch
  • Group controls to simultaneously operate a number of electric roller shutters with a single switch
  • Wind and rain sensors and timers to automatically open or close your electric roller shutters
  • Back-up power for 240V mains powered electric roller shutters via Uninterruptible Power Supply (UPS), so in a power outage you can still open or close your roller shutters
  • Free-wheeling safety clutch to avoid roller shutter damage if an obstruction is encountered while closing the roller shutter
  • Manual Override mechanisms as a safeguard to allow manual opening and closing of your roller shutters in case of a power outage

Electric tubular motors for roller shutters are suitable for all roller shutter sizes all the way up to 250kg in weight.

Spring Assist Lifting Mechanism

Roller shutters fitted with an assist spring as the lifting mechanism allow the roller shutter curtain to be physically raised and lowered by hand. The assist spring balances the weight of the roller shutter curtain and makes lifting and lowering the roller shutter easier and safer. Spring assist lifting mechanisms are suitable for roller shutters starting from 1.0 m wide. For commercial roller shutters wider than 2.7 m fitting a second assist spring is highly recommended to avoid axle torsion and ensure even lifting. In any case, we recommend use of an electric motor for roller shutters weighing more than 60 kg or wider than 3.0 m.

Colours and finish of roller shutter guides, rails and aluminium slats
