50mm Steel Roller Shutter (LOW AND HIGH CYCLE)

The curtain is constructed from 50 x 0.6mm and 50 x 0.8 mm interlocking slats in galvanised steel. Slat thickness depends on the opening width (see the manufacturer). Every second slat is fitted with nylon end clips to minimise lateral movement and to ensure smooth operation. Slats can be replaced individually if damaged.

If ventilation or viewing is a requirement, slotting can be provided. Slotting can also be provided, either in vertical rows or brick pattern and will provide ventilation (which is slightly reduced by any powder coat finish).

Any number of slats can be perforated or slotted to meet the required airflow. Standard curtain finish is galvanised steel, with the option of a powder-coated finish in the Dulux Duralloy or Interpon Contemporary powder coat ranges as standard. Both ranges include suitable matches to the Colourbond colour range. Non-standard colours are available upon request and may attract additional charges.

The bottom rail is made either from extruded aluminium (which can incorporate a weather seal if required) or alternatively from a roll-formed galvanised steel angle, which can also be provided with a weather seal adaptor and rubber seal.

Hand Operation (up to 6.0m2). Chain operation (up to 25.0m²). Electric operation is by a 0.75kW (1 H.P.) single / 3-phase motor gearbox, with a reversing contactor and an up, down, stop standard controller. 

Alternatively, for high-cycle shutters exceeding 40 operations per day, electric operation via a direct-drive motorisation incorporating a springless drum and brake motor. Includes a standard up, down and stop controller. Motors include a hand-chain override mechanism for emergency use in the event of a power failure.

Wiring and commissioning can be provided from a power supply (supplied by others).

Access control systems (card readers, FOBS) by others. A wide range of key switch options, battery backups, remote controls and obstruction detection devices are also available.

Sliding pad bolts (inside or outside) – padlock by others. Suitable for manual shutters only. Chain-operated shutters are locked with a wall-mounted chain lock keeper and padlock, or can be specified with shoot bolts to the bottom rail. Manual locking is not recommended for motorised shutters and is not covered under warranty due to the risk of motor burnout. (unless a safety switch is fitted).

The drum is manufactured from mild steel or galvanised steel tube and fitted with end caps. Engineered Helical coil oil-tempered springs are fitted to an axle inside the drum tube. They are designed to counterbalance the curtain weight when tensioned.

Whilst standard side guides comprise 75mm x 37mm roll-formed steel channel, other options include 60mm x 37mm, 100mm x 37mm. An optional 75mm x 37mm wind-locked guide is also available for additional wind loading and or security.

Brackets are supplied in zinc prime-coated or can be hot-dipped galvanised for certain applications upon request. The door opening must be suitably prepared/designed by others to accommodate the above-mentioned mounting brackets.
